How To Install A Gas Hot Water Heater

How to Install a Gas Water Heater

You may save money on your utility expenses by installing a new gas water heater. How to do it is demonstrated in our video and step-by-step tutorial. Please keep in mind that product pricing, availability, and item numbers may differ from market to market.

Before You Begin

Before committing to a full replacement, conduct a brief maintenance inspection to determine the root cause or the necessity for a new water heater. If you follow the methods outlined below and find that replacement is required, make sure to verify your local building codes before proceeding to confirm that you are in compliance. And, if you’re still not sure, consult with a professional.

Check Water Pressure

The water pressure in your house is critical for all of the equipment that use water. A decrease in pressure reduces the stress placed on plumbing systems and helps to increase the lifespan of appliances and fixtures. When it comes to pressure monitoring, you might want to think about using an inline pressure gauge.

Add an Expansion Tank

To install an expansion tank, follow the instructions outlined below.

Removing the Old Gas Water Heater

To install an expansion tank, follow these instructions.

Preventing Scalds

Even with the temperature gauge set at 120 degrees, the risk of scalds remains a possibility. Children, the elderly, and individuals with delicate skin are particularly at risk of developing skin cancer. Consider adding thermostatic mixing valves to save people from being hurt. Installed at the point of use faucet, fixture, or appliance, a thermostatic mixing valve regulates both the volume and temperature of water by connecting to both the hot and cold water supply lines at the same location.

DIY Water Heater Installation

Burns are still a risk, even when the temperature gauge is set to 120 degrees. Particularly at danger are children, the elderly, and persons with sensitive skin. Consider adding thermostatic mixing valves to save people from being hurt while playing sports. A thermostatic mixing valve, which is installed at the point of use faucet, fixture, or appliance, regulates both the volume and temperature of water by connecting to both the hot and cold water supplies. The settings may be changed inside the valve itself in order to give the most comfortable experience possible.


When your water heater begins to leak, you must act quickly to have it repaired or replaced. We’ll teach you how to set up your own natural gas water heater in less than a day’s time. Even if you do not require a new water heater at this time, it is likely that you will require one within the next few years. Water heaters typically have a lifespan of seven to fifteen years. If yours is beginning to show signs of wear, this post is also for you. If you’re familiar with basic equipment and have a little expertise soldering copper, replacing a water heater shouldn’t be too tough.

Tools Required

  • Water and gas piping
  • Discharge pipe
  • Fittings
  • Pipe thread compound
  • Pressure relief valve
  • Solder. Ventilation pipe and connections
  • Pressure relief valve.

Getting Started Installing Your New Hot Water Tank

In this example, we’re swapping out a natural gas water heater for an electric water heater. The processes for replacing a propane water heater are identical to those for replacing an electric water heater, and the steps for replacing both are comparable. In any event, when it comes to arranging a water heater replacement, it’s best to be cautious. Call your local department of inspections and inquire as to whether or not you require a permit. Also, be certain that your work is checked by a plumbing or electrical inspector.

Plumbers normally charge between $45 and $65 per hour and can complete the installation of a water heater in a day or as little as 6-8 hours.

Gas water heaters with particular venting systems are also available, although they are more costly. However, because they are more difficult to install, we will not be covering them in this article.

Water Heater Parts and Breakdown

  • Fire pipe, cold water shutoff valve, draft diverter, temperature and pressure relief valve, overflow pipe, hot water outlet, anticorrosion anode rod, dip tube, elements, insulation, drain valve, thermostat or control valve, burner, thermocouple, gas supply valve, and more.

When to get a new water heater

When the tank of your water heater leaks, your water heater is out of commission. An indication that your water heater needs to be replaced is a gradual drop beneath the unit, which commonly manifests itself as a trail of discolored water. This indicates that the steel tank has corroded through and will be unable to be repaired. Other symptoms, such as little or no hot water, are typically indicative of other water heater repair issues that may be resolved by you. If you notice a drop, make a plan to get the water heater replaced as soon as possible.

  1. New water heaters are sent with detailed installation instructions as well as several cautions to ensure that the gas, electrical, and other connections are handled properly.
  2. However, you should be aware that you will be dealing with natural gas, propane, or electricity, all of which are potentially harmful.
  3. And, after you’re finished, get your work examined.
  4. You should explain to your local plumbing inspector how you want to install your new connections, including the sorts of materials you intend to use.

Mr. Fix-It-Up-For-The-Family See the Additional Information section at the end of this article for instructions on how to print this image.

Figure B: Connections for Steel and Plastic Pipe

Mr. Fix-It-Up-For-The-Family Water supply pipes in many residences are made of galvanized steel or polyvinyl chloride (CPVC). Replaceable galvanized steel pipes are quite difficult to come by. Using our photo series, we propose that you return the pipes to their original tees and screw on a plastic-lined galvanized nipple before finishing the connections with copper. Plastic tubing should be kept at least 6 inches away from the vent and tank due to the possibility of heat accumulation. Using a specific connection, you may make the transition from plastic to copper.

Flexible copper connectors are less difficult to install than solid copper connectors, which is especially important when the existing pipes and tank inlets do not match up.

If yours does, take extra care not to pinch or kink them when handling them.

Project step-by-step (12)

Mr. Fix-It-Up-For-Us. Galvanized steel or polyvinyl chloride (CPVC) water supply pipes are often seen in many residences. Replacement of galvanized steel pipes is a time-consuming endeavor. Using our photo series, we propose that you return the pipes to their original tees and screw on a plastic-lined galvanized nipple before connecting the pipes with copper. Plastic tubing should be kept at least 6 inches away from the vent and tank due to the possibility of heat accumulation in the material.

You can find it everywhere CPVC is marketed.

However, they are not permitted by all local ordinances. It is very important not to squeeze or kink yours if yours does this. It is possible that you will have a leak.

Drain the water in the tank

Connect a garden hose to the drain valve and use it to drain the water that has accumulated in the tank. The water will be boiling hot, so proceed with caution! With a pair of wrenches, disconnect the gas line at the neighboring union and remove the pipe from the gas control valve with a pipe wrench to complete the task.

Cut off the water lines

The vent pipe should be moved to the side once it has been unscrewed from the vent hood. After that, using a tube cutter, cut the hot and cold water lines. For galvanized pipe, remove the unions and, if you have them, remove the nuts on the flexible connections as well. Move the old water heater to the side of the room. Step number four.

Attach the relief valve

Teflon tape should be used to seal the threads of the new temperature and pressure relief valve (three turns). With a pipe wrench, tighten it inside the tank until it is completely sealed. Glue a copper discharge pipe to the wall (see Fig. A for routing details). Step number five.

Attach pipe assemblies

Solder fresh copper adapters to 6-in. lengths of 3/4-in. copper pipe and screw the assemblies into the hot water outlet and cold water inlet ports on the top of the tank’s tank’s tank’s tank. Make use of short, plastic-lined nipples to protect your pipes from galvanic corrosion, especially if you have hard water or if they are required by your local building standards. Step 6: Organize your thoughts and feelings about the situation.

Attach the water lines

Slide the new water heater into position, recut or lengthen the old tubing to connect it to the new, and solder the tubing together using copper slip couplings to complete the installation. If the tubing does not line up properly, use pairs of 45-degree elbows to adjust the alignment of the lines. Step 7 – Organize your time and resources.

Reattach the vent

Reconnect the vent if necessary. Place it securely over the draft hood and secure it with three 3/8-in. No. 6 sheet metal screws to hold it in place. Prepare the holes by drilling them beforehand. Before turning at the first elbow, the vent should rise at least 12 inches vertically from the floor. In this eighth step, you will learn how to use a comma to separate the words “and” and “and not.”

Use two wrenches to attach the gas line

Reconnect the gas line if necessary. Pipe joint compound should be applied to the threaded ends before screwing the first nipple into the gas valve. To minimize straining the valve, use two pipe wrenches at the same time. Reassemble the remaining nipples, concluding with the union at the end of the process (Photo 2). Then, in order to fill the tank, perform these four steps: To check for leaks, perform the following steps: (1) cut off the main water valve; (2) re-connect the water at the main shutoff; (3) open the cold-water valve on the water heater (but do not close it); and (4) turn on a nearby hot-water faucet until water flows out.

Check for backdrafting

The majority of water heaters rely on a natural airflow to carry combustion emissions up the chimney and out of the building. If the draft does not operate, the fumes, which may contain lethal carbon monoxide, will be released into your home and cause you to become sick. Check the draft when you’ve finished installing everything. Close all of your external doors and windows, and put on the exhaust fans in your kitchen and bathroom. Continue to run a hot water faucet until you hear the gas burner in your water heater come to life.

Ideally, the smoke should be drawn upward through the vent pipe. If the smoke does not draw, this indicates that the burner’s fumes are not escaping. Turn off the gas supply to the water heater and contact a certified plumber to diagnose and remedy the problem. Step number ten.

Check for leaks

Check for leaks by turning on the gas and squeezing a 50-50 combination of dishwashing liquid and water over the connection points. If there are bubbles in the mixture, you have a leak. Joints that are leaking should be tightened or reconnected. When you’re finished, wipe the joints down with a clean cloth. Make an appointment with the plumbing inspector to have them go at your work. Follow the how-to instructions that are included with the photographs to ensure that the connections are secure.Step 11

Light the pilot light

The pilot light should be turned on in accordance with the manufacturer’s instructions. (If you are using an electric water heater, switch the power on at the main panel after the electrical inspector has checked your work.) Finally, adjust the temperature to 120 degrees Fahrenheit according to the manufacturer’s recommendations. The pilot light in the new water heater should be lit, then the temperature setting should be adjusted.

Installation Details for Electric Water Heaters

At your main electrical panel, turn off all power to your water heater, then turn it back on. After that, empty the water heater in the same manner as you would a gas water heater. As soon as the water heater has been drained, separate the electrical wires from the screw terminals under the access panel, which is normally situated towards the top of the water heater. To handle all of the electrical wiring, you should engage an electrician if you don’t have any prior knowledge with it. When it comes to wiring the new water heater, follow the manufacturer’s instructions.

  1. x 4-in.
  2. metal electrical box on the wall or ceiling near the water heater, route the old wires to the box, and then run a new length of armored cable or electrical conduit to the water heater to complete the installation.
  3. The circuit should also have a shutdown switch that is visible from the vicinity of the water heater.
  4. You’ll almost certainly require a permit.
  5. Aluminum wire needs specific care and handling.
  6. This wiring is a dull gray color, rather than the drab orange color that is characteristic of copper wiring.

How to Dispose of a Water Heater

In this video lesson, Jeff Gorton, an editor at The Family Handyman, will show you how to remove and dispose of a water heater in the proper manner. He will also demonstrate a simple method of transporting a water heater out of your home, even if you are working on your own.

These tips will make your work go faster and easier:

  • To avoid modifying the length of your water, gas, or electrical lines, take note of the height of your existing water heater and get a new one that is the same height
  • On older water heaters, the drain valve (Photo 2) frequently becomes clogged. Please be patient if the water drains slowly. WARNING: The temperature is really high! TIP: Turn off your water heater two hours before you want to use it to enable the water to cool. Water heaters are around 150 pounds in weight. When you’re moving the old one out and wheeling the new one in, you’ll need a strong partner or a dolly to assist you. Ordinarily, garbage collection agencies charge approximately $25 to remove the old one. Before you begin, go to a plumbing supply or hardware store, or a home center, and purchase the equipment and materials seen below. Check the sizes of the water supply pipes (the majority will be 3/4 in., as shown in our photographs) and purchase the fittings that are the proper size. If you have everything you need, you should be able to complete the work in four to six hours (provided there are no major problems!). This safety mechanism, which controls tank pressure and prevents it from bursting, is located in the tank’s pressure relief valve assembly (Photo 4). It is necessary to include a fresh one with each installation. The discharge pipe must be kept clear of impediments in order for the valve to function correctly (see Fig. A). Use 3/4-in. plastic-lined nipples (about $2 each
  • Photo 5 and Fig. A) to attach other metals, mainly copper tubing to the steel tank, in areas where the water is highly mineralized or where it is needed by municipal laws. This has the effect of slowing rusting. In order to avoid heating the tank itself during soldering, solder the copper fittings before screwing them to the tank (Photo 5)
  • Slip couplings should be used to link the existing and new water lines (Photo 6). (Photo 6). They do not have an internal stop, in contrast to normal couplings. Alternatively, you may slip them on, align the copper tubing, then slide them back and center them over the junction
  • However, the new inlets and outlets on the tank don’t always line up with the old supply lines, and vice versa. If required, solder in a pair of 45-degree fittings to ensure that each line is offset. While you’re doing it, you should also replace the old cutoff valve with a new ball valve (Photo 6). The diameter of the vents is determined by the amount of heat produced by the water heater. In order to achieve the ideal draft, you may need to raise or reduce the ventilation size. CAUTION: If you’re not sure whether or not your chimney has a liner, consult with a plumbing inspector. Make gas connections using solid steel pipe (Photo 8) or soft copper tubing with flare fittings (Fig. A). Both are more dependable and less expensive than flexible stainless steel connections, which are not usually allowed in some applications. For the same reasons, rigid copper water supply lines should be used rather than flexible copper water supply lines
  • If your water heater replacement is located in a location where leaking might cause damage to the floor or other elements of the home, lay a pan of an appropriate size beneath it (metal for gas water heaters). a drain tube that connects to a home drain or another suitable site must be installed in the pan (outdoors where permitted). If a leak might cause damage to the flooring, the discharge tube for the temperature and pressure relief valves must also connect to a drain. If routing is a problem, consult with your local plumbing inspector about possible solutions. Special straps should be used to secure your water heater to the wall if you reside in an earthquake-prone location (Fig. A
  • Available at plumbing stores and home centers). If they are necessary, your plumbing inspector will inform you of this. Ensure that the new water temperature setting does not exceed 120 degrees Fahrenheit to avoid scorching

There are few things that are more frustrating than a broken water heater. When there is no hot water, there are no clean dishes or clothing to wash, and you have to take chilly showers. You should consider replacing your water heater if you’re having troubles with your current unit. DIYing the replacement of your air conditioner might save you money. This Might Also Be of Interest to You: What is the approximate cost of repairing or replacing your water heater? When shopping for a new water heater, it is important to understand that water heater installation is not a task for inexperienced individuals.

Furthermore, if you make a mistake throughout the procedure, you might do harm to your home.

Knowing how to connect the water and gas lines to the new heater, as well as how to start the pilot light, will be necessary.

Can I Install a Gas Water Heater Myself?

You can easily do a gas water heater installation on your own if you’re confident in your abilities; but, if money is your major concern, it may actually be more cost-effective to hire a professional to assist you. The Consumer Reports website states that 90 percent of water heater replacements are necessary because the previous water heater has failed. If you don’t know how to install a gas water heater, you don’t want to have to figure it out when water is gushing all over the place. It might also be dangerous to do it on your own if you have no prior expertise or knowledge of the subject.

A gas leak is not a DIY job you should take on unless you are prepared to take a significant risk to your house and the environment.

What Kind of Water Heater Do I Own?

You can easily do a gas water heater installation on your own if you’re confident in your abilities. However, if money is your major concern, it may actually be more cost-effective to hire a professional to assist you. The Consumer Reports website states that 90 percent of water heater replacements are performed because the existing water heater has failed. If you don’t know how to install a gas water heater, you don’t want to have to figure it out when water is gushing all over you. Attempting to accomplish it on your own without prior expertise or knowledge of the subject might also be dangerous.

The installation should only be done by a professional if you are completely unaware of what you’re doing. Gas leaks are a severe threat to both your house and the environment, so don’t take any chances with this DIY project. It is possible to have leaks if the waterline is not correctly attached.

Choosing the Right Water Heater

Pick whether you want to fuel your water heater with natural gas or electricity, and then decide whether you want a tank-style water heater or a tankless water heater. The choice between gas and electric will be the more significant one since it will have the most influence on your monthly energy bill and maintenance expenditures.

Electric Water Heaters

Electric water heaters are the most straightforward to set up. In addition, they are less expensive to acquire. However, there are certain disadvantages to using them. Here are some pros and downsides to take into consideration:

  • Electric water heaters require less maintenance than gas water heaters since they are not linked to a natural gas line. As a result, there is no danger of gas leaks, which can result in explosions or carbon monoxide poisoning. When it comes to the water heater itself, you will save money. Power, on the other hand, is more expensive than natural gas, therefore you will see an increase in your electricity costs as a result of this saving. If you lose power, you will be without hot water for a period of time since the water heater requires electricity to work. Compared to its gas-powered equivalents, electric water heaters heat water at a slower rate. Electric water heaters with high efficiency are not available on the market.

Gas Water Heaters

Installing a gas water heater will necessitate the use of more advanced skills and will take longer than installing an electric water heater. If you’re thinking about installing a gas water heating system, there are some advantages and disadvantages to consider. These include:

  • Natural gas is significantly less expensive than electricity. In order to save money on your utilities, this is the best option for you
  • Units fuelled by natural gas heat water fast. When compared to an electric water heater, a tankless gas water heater is far more effective and efficient. If your electricity goes out, your water heater will continue to run normally without interruption. During storms or other power outages, this may be quite beneficial. Gas water heaters are more costly to install than electric water heaters. However, because they are less expensive to operate, the money you save on your power bill will more than equal the original cost over time.

In addition, there are safety risks associated with having a gas system. A gas leak may necessitate the hiring of a professional to solve the issue swiftly, and you may be exposed to carbon monoxide and combustible gas as a result of the leak. It is possible to alleviate some of the safety issues associated with using a gas water heating system by installing carbon monoxide detectors in your house. The installation, inspection, and maintenance of your equipment should be handled by a qualified specialist.

Check your connections on a regular basis so that you are aware of when you need to make repairs.

The fact is that they are more cost-effective in the long term.

Tankless Water Heaters Vs. Storage Water Heaters

The decision on whether or not to go with a tankless unit is dependent on the amount of demand you intend to place on the unit as well as the environment in which you reside. Water heaters with no tanks take up a fraction of the area required by tanks with tanks, but they are unable to store any hot water. However, after the water is heated, they can produce around four gallons of hot water every minute, which is a significant increase over the previous model. Despite the fact that this may appear to be a lot, it may not be enough if you’re also running the shower, dishwasher, and washing machine at the same time.

  • Another disadvantage of living in a colder region is that cold water takes longer to heat, so if you’re starting with water that comes in from chilly pipes, it will increase the amount of time it takes to warm the water.
  • Tank systems are significantly more common, and the majority of homes are already equipped to accommodate them.
  • An unvented tanked system works by continuously heating the water in your storage tank, allowing you to have hot water on demand anytime you turn on the water faucet.
  • The majority of individuals choose for a tank with a size between 40 and 55 gallons.

Because the water in the tank is always hot, you waste a significant amount of energy heating water that may or may not be utilized, making these systems less environmentally friendly than other options. Additional Related Articles:

How Do I Install a Gas Water Heater?

When dealing with gas lines, the most important thing to remember is that safety comes first. Make certain that your gas and water are totally turned off while you are working in order to avoid mishaps and serious injury. Before using the new system, check to see whether there are any leaks. If you are not familiar with all of the safety standards for installing a water heater, we do not advocate attempting to do it yourself. An installation guide for the most popular form of water heater, a gas unit with a storage tank, is provided in this step-by-step instruction.

Step 1: Measure and Prepare the Space

The most effective method for accomplishing this is to measure the unit you presently own and then purchase a new water heater that matches those measurements. Make certain that the new water heater complies with any applicable local laws or ordinances so that you don’t install it only to discover that you have to remove it because it doesn’t meet the requirements.

Step 2: Cut Off the Water Supply

Close the water main shutoff valve, which will shut off the water supply to your whole home. In addition, turn the water control valve on the unit itself to the off position. Then, turn on all of your faucets around your house to drain as much hot water as you possibly can from your system. Keep the faucets open while the old unit is being removed.

Step 3: Drain the Tank

Drain the tank by attaching a hose to the drain valve and turning it on. You can direct the water to a location outside your house, or you can dump it into buckets or a drain in your home that feeds to the sewage treatment plant. Even though this procedure may take a few minutes or longer, it’s critical to ensure that the tank is completely empty before proceeding.

Step 4: Disconnect the Gas and the Water

A tubing cutter will be required for this stage, if the lines have been soldered together before. Because your water should already be turned off, begin by turning off the gas to the water heater. If you don’t notice any shutdown valves near the heater, you’ll have to turn off the main water supply to the house instead. If you sand the pipe before disconnecting it, it may be easier to solder the new pipe when you reconnect it. Remove the gas pipes, but leave the tank tee and sediment trap in their original locations for safety reasons.

Step 5: Remove the Overflow Pipe and Pressure Release Valve

A tubing cutter will be required for this step if the lines have been soldered together. Because your water should already be turned off, begin by turning off the gas to the water heater. It is necessary to turn off the main water supply to the house if there are no shutdown valves near the heater. If you sand the pipe before disconnecting it, it may be easier to solder the new pipe when you reconnect it later. Take off all of the gas pipes, but leave the tank tee and sediment trap in their original locations.

Step 6: Clean the Floor

Make certain that you have adequate room to work comfortably. For adequate ventilation, place the new unit at least 6 inches away from any walls or open spaces. Install the new unit and use a level to ensure that it is sitting flat on the floor.

Step 7: Hook Up the Flue Hat

Make sure you have adequate room to do your task before you begin.

For adequate ventilation, the new unit should be placed at least 6 inches away from any walls or open area. Place the new unit in its proper location and check that it is level with the ground.

Step 8: Solder the Gas Line

It will be necessary to solder the pipe to rejoin it if you used a tubing cutter on the gas line during the removal process. It’s also important to reconnect the water supply line. After that, you’ll need to reinstall the pressure relief valve to complete the process. At this stage, you will need to connect the gas line and check it for leaks to ensure that there are no problems. Wash the area with soapy water and check for bubbles if there is any sign of gas leakage.

Step 9: Light the Pilot Light

Finally, re-ignite the pilot light and re-connect the water supply. Make careful to turn off any faucets that were left open prior to this procedure.

Is It Difficult to Replace a Gas Water Heater?

Installing a gas water heater is not normally a do-it-yourself project for most homes; you cannot learn how to install a gas water heater in a day or two. If you are not adequately equipped and have no prior plumbing knowledge, doing this procedure can be highly risky. There are a plethora of possibilities for things to go wrong. In addition, you must ensure that your system complies with all applicable building requirements in your area. We recommend that you use a professional plumber for installation since a plumber will be able to install your unit quickly, will frequently be able to dispose of the old unit, and will be familiar with the standards and regulations that control what sort of system you are permitted to install.

How Long Does It Take to Install a Gas Water Heater?

A competent plumber can generally perform the installation in less than two hours with the proper tools. Given the weight of a tank-style water heater, a plumber may enlist the assistance of a coworker in order to complete the removal successfully. It’s possible that you won’t be able to move the unit on your own. If you have no prior expertise, the procedure might take several hours — or possibly all day — since you will need to spend a significant amount of time making sure you understand where everything is supposed to go.

Gas Water Heater Installation: A Step-by-Step DIY Guide

Gas water heater installation may appear to be a job best left to the professionals, but it is not quite as complex as you may assume. Certainly, hiring a professional to complete the work for you is the most convenient option to complete the task at hand. Installing your gas water heater, on the other hand, is a terrific do-it-yourself job if you want to save a little money while still gaining a sense of success. In most cases, it’s advisable to go with the same fuel type (gas or electric) when purchasing a new water heater unless there’s a compelling reason to do otherwise.

They can provide you with information about the local plumbing codes as well as whether or not you will require a municipal permit.

If you hire a professional, you won’t have to worry about this since they will remove your old water heater from your property for you. It is not difficult, however, to replace a gas water heater if you like DIY projects and would want to save money in the process.

Preparing to Install a Gas Water Heater

The chances are considerable that your water heater has reached the end of its useful life and will need to be replaced if it is more than 10 years old. Prior to purchasing a new water heater, however, it is worthwhile to attempt to resolve the issue first using the methods described above. If your water heater is leaking, it is possible that the problem can be resolved. If, on the other hand, the source of the leak is the tank itself, you will need to have the device repaired or replaced.

Tools and Supplies Needed

  • Examine the label on the back of your old water heater. It should include information on the annual energy consumption as well as the tank capacity. Having both of these details handy while searching for a new water heater is a great idea. Before removing your old water heater, we recommend that you examine your water heater vent system to ensure that it is in excellent operating order and that it is functioning correctly. Remove your old heater by disconnecting it and draining it, then removing it with a hand truck. If there is an excessive quantity of sediment buildup in your water heater tank, the drain valve may get clogged. This article will guide you through the process of draining the tank. Take caution when handling the vent pipe. In good condition, you may use it with your new water heater to save money on your energy bills. This is also possible if the Temperature/Pressure Discharge Pipe is in good condition
  • However, this is not always the case. If your water heater was plumbed with copper pipes, you may need to use a tubing cutter to cut the copper pipes in order to repair them. Keep as much pipe as possible intact if this is the case.

How to Install a Gas Water Heater

Follow these step-by-step instructions to learn how to install a gas water heater, and then watch the video to learn more.

Install Earthquake Straps

The first step is to use a tape measure to determine the placement of the two earthquake straps.

  • In the case of an earthquake, these seismic straps will aid to support the tank against the wall, so preventing it from tumbling over. Measure the water heater from the ground up and mark the wall with the relevant measurements: The upper earthquake strap should be positioned a few inches below the T P Valve on the T P Valve assembly. The lower strap should be positioned a few inches above the gas regulator, and vice versa.

By measuring from the ground up and noting the height with a pencil, you can determine where the picture should be hung on the wall. The seismic strap bracket should be mounted to the wall. Make certain that the screw “catches” a stud. When not in use, the seismic strap should be placed next to the tank. In order to properly tighten the screws, it may be required to “swing” the bracket 180 degrees. Install the new water heater in its proper location. Placing the water heater in a drain pan and connecting the existing piping to the inlet and outlet connections of the water heater are the next steps.

It is not necessary to secure the water heater with earthquake straps.

Connect the Water Supply

Step 2: Using a wire brush, clean the threads of the cold and hot water lines. Installing a ball valve on the coldwater supply line is strongly recommended if the system does not already have one. Connect the water supply lines for hot and cold water. Use caution while installing copper flexible water lines (as seen in the video), since they are prone to kinking if not handled properly. Using the procedure demonstrated in the video, loop the flex connection around many times. Leave enough slack in both the hot and cold water supply lines to allow for expansion and contraction of the vent area.

It is possible to extend the life of a water heater by using dielectric nipples to minimize corrosion between two dissimilar metals.

Sometimes they come pre-installed, but if not, we strongly advise that you get a complete set.

Install the Vent Hood

Step 3Attach the vent hood to the top of the water heater, above the flue that runs through it.

Remember to follow the directions that came with your water heater because the process differs from one manufacturer to another. To attach the vent hood in place, self-tapping sheet metal screws should be used.

Install the Vent Piping

4. If your vent pipe is not damaged, you should be able to reuse it with your new water heater. Consult your water heater’s owner’s handbook to determine the proper vent pipe diameter. If the suggested vent pipe diameter is greater than the diameter of the vent hood, a reducer should not be utilized. In order to begin assembling the adjustable vent pipe, insert one end into the water heater vent hood and join the remaining pipe components. Check the manufacturer’s instructions for your water heater to ensure that the diameter is proper.

This will allow the vent pipe to be aligned as closely as possible to a straight line.

To attach the vent parts to the water heater vent hood and to the other vent sections, use self-tapping sheet metal screws to fasten them together.

Check your local code to see if there are any restrictions.

Install the Gas Connection

Step 5Confirm sure the gas supply is turned off by turning it on and off again. Cleaning the pipe fitting on the supply pipe with a wire brush is then necessary. By opening and shutting the valve, you may flush the line. Remove the sticker from the water heater’s gas control valve and replace it with a plug. This is the location where the gas line will be connected. Remove the gas nipple from the flexible gas line by unscrewing it. Many places, particularly earthquake-prone ones, necessitate the installation of flexible gas lines.

  1. Find a Local Plumber in your area.
  2. The thread of the gas nipple is threaded with a paintpipe joint compound.
  3. Use of gas plumbers tape, which is yellow and less dirty, is another choice; nevertheless, you should never use white Teflon tape since it is toxic.
  4. It should be moderately restrictive.
  5. We recommend that you tighten the nipple with two wrenches to avoid any damage.
  6. Connect the gas flexible line to the gas supply line and the gas control valve on the water heater.
  7. If required, make a loop out of the surplus line.
  8. Turning on the gas should be avoided at all costs.
  9. When you turn on the hot water faucet, you will be notified when the tank is full.
  10. When water is running from the hot water faucet, this indicates that the tank is full.

Allow the water to run for a few minutes before turning it off. This will get rid of all of the air that is currently in the tank. As long as the tank is not completely filled and all of the air has been drained out of the tank and lines, the water will splutter.

Connect the Earthquake Straps

Seventh step: Wrap a pair of earthquake straps around the water heater and attach them together. Avoid pulling the straps too tightly; they should be snug but not too so. Then, using clips, secure the extra strap in place. Find Local Plumbing Professionals

Connect the T P Drain Pipe

Step 8If the T P drain pipe from your previous water heater is in good condition, you may be able to reuse it. However, it is possible that you will need to construct a new T P drain pipe. To do this, use a tube cutter to measure and cut a copper pipe. Put a bucket underneath the T P drainage pipe if you do not have a floor drain installed. The end of the drain pipe should not be more than 6 inches above the ground or the bucket it is connected to. Turn on the gas supply valve. To ignite the pilot, go to the owner’s handbook for your water heater.

  1. Place the lower dial on the gas regulator to ” Pilot Lighting ” and then turn the control knob on the gas regulator to ” PILOT ” mode to complete the process.
  2. Once you have waited a few seconds, click the ignitor button while simultaneously pressing the control knob to start the engine.
  3. Another type of sight glass will allow you to visually inspect whether or not the flame has caught.
  4. If the flames were to ignite:
  • Press the control knob for 45 to 60 seconds in a continuous motion. After releasing control knob, double-check to see if the pilot is still glowing. To switch on the pilot if it is still lighted, move the control knob to the ON position.

Lower the dial to the temperature you choose for your drinking water. As a starting point, make use of the manufacturer recommended configuration. The ideal temperature setting is 120 degrees.

Test Gas Lines for Leaks

Step 10: Check for gas leaks by spraying any gas connections with a flammable liquid. You may either make your own solution (1 part dish detergent to 2 parts water) or buy Leak Detection Solution, which is available at most hardware stores. If you observe any “bubbling,” this is a sign that gas is leaking from the system. Applying a wrench to the loose connection and checking it again is recommended.

Watch the Video

After you’ve completed the installation of your gas water heater, there are a few further considerations to make. First and foremost, always check your vents to ensure that they are drawing correctly. If they are not, we urge that you seek the assistance of a specialist to fix the matter. You may learn how to achieve this by watching the video below.

Watch the Video

After a couple of hours, examine the T P discharge pipe for leaks or damage. The fact that the hose is pouring indicates that the pressure inside your tank is likely to be excessive. Turn off the gas supply and contact an expert as soon as possible. Keeping a carbon monixide detector close by your gas water heater is strongly recommended by us.

Who Is Qualified to Perform a Gas Water Heater Installation? – Maeser Master Services

In spite of the fact that installing a new propane hot water heater may not appear to be a huge concern, it entails working with potentially dangerous systems that not every homeowner is equipped to handle without assistance. The following information will provide you with everything you require when deciding who will perform your gas water heater installation.

The Basics: How to Install a Gas Water Heater

If all you have to do is substitute out your water heater, it may appear to be a straightforward procedure. Initially, it appears to be a straightforward process: you drain the old tank, cut off the gas and water, unplug and carry away everything associated with the old heater before installing the new heater. There aren’t many attachments to disconnect; the only ones are the gas supply and exhaust (flue), as well as the lines for cold and hot water coming into and out of the unit. However, even though it appears to be a straightforward project that doesn’t take much time to complete, home improvement websites such as Home Depot classify the complexity of gas water heater installation as “advanced.” For a good reason, this is the case.

Safety Concerns

Despite the fact that the installation appears to be straightforward, it is the fact that you will be working with gas that warrants the “advanced” classification for this operation. Working with gas has the potential to be extremely harmful for you, your family, and anybody else who may be in close proximity to your house or who may share walls with you. When you install your new water heater, you will need to switch off the gas to allow you to detach the supply line and connect it to the new hot water heater, which will take some time.

Once you’ve completed the installation of the new heater, you may turn the gas back on, but you’ll need to inspect the gas line for leaks.

The difference between an amateur and a professional installation is that the former has more expertise dealing with gas lines and so requires less trial and error, while the latter has the tools to identify gas leaks with more accuracy, thereby making you and your family safer.

Plumbing Expertise

The fact that you’ll be working with gas, despite the seeming ease of the installation, supports the “advanced” grade for this project. It is possible that working with gas will put you and your family in great risk as well as anybody who shares your house’s walls or who lives in close proximity to your home. During the installation of your new hot water heater, you will need to cut off the gas in order to disconnect the existing supply line and connect it to the new hot water heater. It’s critical that the gas supply line, as well as the heat trap and exhaust, be all properly installed and configured.

This generally entails slathering the connection with soapy water and keeping an eye out for bubbles in the process for the average amateur at home.

The difference between an amateur and a professional installation is that the former has more expertise dealing with gas lines and so requires less trial and error, while the latter has the tools to identify gas leaks with more accuracy, thereby making you and your family safer.

Updates and Upgrades

If your system has to be upgraded to meet contemporary requirements, or if you’re thinking about upgrading to a more advanced hot water system, such as a tankless gas water heater, you’re looking at a considerably more involved project than just replacing out one water heater for another. If you’re replacing a standard storage water heater with a tankless system, you’ll need to retrofit the tankless system with new gas lines, new water lines, and a new ventilation system, which will make the conversion considerably more difficult for the ordinary do-it-yourselfer.

This makes the transition considerably more difficult for the ordinary do-it-yourselfer who doesn’t have the necessary abilities.

What Size Tank Do You Need?

The capacity of a gas storage tank water heater can range from 30 to 75 gallons, depending on your requirements. When you turn on a hot water faucet or run hot water through a washing machine or dishwasher, water pipes extract hot water from your tank. Using a tube, heated water is pulled from the tank’s top and replenished with cold water that is delivered to the bottom by the tube. Gas water heater installation can only be accomplished in a home that already has gas running through it. Hot water heater tanks are often covered by a 6 to 12 year leakage guarantee, which varies based on the size, brand, and model of the unit purchased.

Every day, the average American home consumes more than 60 gallons of hot water. Hot water is so crucial that it accounts for about 20% of the total energy consumption on a monthly basis. Did you know that water heaters have a lifespan of around 10 years? When your water heater reaches the age of around 8 years, it is time to consider replacing it. It is critical to avoid making costly mistakes throughout the water heater installation process in order to prevent wasting your money. If this is your first time purchasing a new water heater, this article will assist you.

1. Underestimating Your Hot Water Needs

Purchasing a water heater that is inadequate in order to save money will result in a higher energy bill. As an alternative, take the time to determine how much hot water your household consumes. The amount of hot water you consume during the busiest period of the day is referred to as your peak hour demand. To figure it out, utilize the following information:

  • Every 10 minutes, the shower uses 10 gallons of water
  • Hand-washing dishes use 2 gallons per minute
  • The dishwasher uses 6 gallons per use
  • And the washing machine uses 7 gallons per use

When selecting a water heater, choose one that can provide a gallon or two more per minute than your peak hour usage. Look for the EnergyGuide label to see what information is available.

2. Ignoring New Technology

Renewable energy sources are being incorporated into innovative water heating equipment. Solar water heaters are an excellent illustration of this. Using the heat from the sun, these heaters warm water for your household.

A solar water heater can reduce your water heating bills by half if you install one. Several types of solar water heaters do not function properly in cold areas. Closed-loop heating systems are the greatest option for households in Michigan since they are more energy efficient.

3. Overlooking Energy Efficient Water Heaters

The cost of a tank water heater has reached an all-time low. The disadvantage of these heaters is that they require a lot of maintenance and replacement parts. Each visit to the repair shop costs around $600. Tankless water heaters are more energy efficient and last twice as long as traditional tank water heaters. Because they do not have a water tank, there is less silt in the system, which reduces the likelihood of rust formation. Tankless systems are avoided by homeowners because they cost twice as much as traditional tank heaters.

4. Failing to Follow Installation Instructions

Installation manuals and building codes are available to ensure the safety of your house and family. Before beginning a water heater installation process, be sure you have read all of the directions. Organize your thoughts and make a list of the tools you’ll need for the endeavor. Missing a single step, such as failing to secure the water heater, can result in catastrophic floods. Flooding encourages the growth of harmful fungus in your house. Mold may also devour porous materials such as drywall and other building components.

The permits ensure that the installer complies with all applicable safety and building requirements during the installation process.

5. Installing the Water Heater in an Inaccessible Spot

When living in a smaller house, finding space for your water heater might be difficult. In certain cases, this leads to homeowners putting heaters wherever there is available space. The water heater may not be maintained as frequently as it should be if it is difficult to have access to it. Rust and sediment seeps as a result of carelessness. Here are a few pointers on where to put your water heater:

  • Keep your water heater within 20 feet of the entryway or crawlspace access
  • Otherwise, it might cause damage. Make certain that the crawlspace hole is large enough to allow for comfortable entry and exit. Installation of enough illumination at the entrance to make maintenance visits more manageable. When it comes to electric water heaters, install a power switch in case of floods.

Installing a gas water heater in an enclosed room that has not been intended for it is not recommended. Carbon monoxide is produced by gas heaters. If your water heater is housed in a closet, it has the potential to harm you and your family.

6. The Drain Line is In the Wrong Position

The TPR valve is located on the side of the water heater tank. When the tank becomes excessively hot or over-pressurized, this valve allows hot water to be released. During the installation process, you will need to connect a drain line to the TPR valve in order to guide the flow of water. The drain line should empties into the nearest floor drain, if one is available. Never connect a drain line to a drain pipe or vice versa. It has the potential to cause polluted water to back up into the water heater.

If the heater vents while being serviced, the spraying water will cause you to burn your skin.

7. Don’t Dry Fire the New Water Heater

Never use an electric water heater if the tank is completely depleted of water. A dry fire is a slang term for this type of blunder. The upper heating element of a dry-fired water heater will be completely destroyed. The cost of replacing parts is quite inexpensive. However, the repair will increase the amount of time your family will be without hot water. Always put water through your electric water heater before turning on the stove to avoid a dry fire catastrophe.

Pour hot water into your kitchen sink by turning it all the way on and letting it run for 3-4 minutes. There are air bubbles in the pipe, which will cause the noises you may hear. You shouldn’t be concerned about them unless they linger for more than a few minutes.

8. Refusing to Ask For Help with Your Water Heater Installation

It is OK to acknowledge that you lack the necessary abilities to finish a home improvement job. Installing water heaters necessitates a thorough understanding of plumbing, electrical, and gas systems. Professionals require years of training to master all of these abilities. Bringing in a professional who is knowledgeable about water heater installation will save you money. In comparison to a dry fire, they are less prone to make mistakes. They also know how to deal with any unexpected complications that may arise throughout the installation process.

Most likely, you do not have the essential tools to deal with any unexpected problems that may arise.
