The Dangers of Using Extremely Hot Water

It’s possible that you’re discovering for the first time that skin burns may occur even at temperatures below 100 degrees Fahrenheit. Serious first-degree burns can occur when the following temperature settings are utilized:

  1. Using hot water at 140 degrees Fahrenheit for three seconds or longer
  3. Using 120 degrees Fahrenheit hot water for at least eight minutes
  5. Using hot water at 130 degrees Fahrenheit for at least twenty seconds
  1. Because of this, you must never compromise on the safety of yourself or your children when it comes to water heater temps.
  2. To ensure that the water is safe for your infant, dip your own finger into it before putting him or her in the tub.
  3. Never leave your infant alone in the bathtub with a hot water supply running, regardless of whether the temperature of the water is mild or hotter than normal.

It is essential to check the temperature of the water before bathing your children or grandchildren.

Key points to remember

There are many key considerations to bear in mind while adjusting the temperature settings on your Rinnai tankless water heater:

  1. The temperature of your water heater unit can only be adjusted between 98F and 110F degrees at any given time if it is currently generating hot water
  2. otherwise, you can only modify the temperature between 98F and 110F degrees
  3. or you can only adjust the temperature in the middle of the range.
  4. If the Rinnai tankless water heater is being utilized in a business context, it is necessary to review the recommended codes for adjusting the water temperature. It is possible that you will not be permitted to set it to the 120F setting that you would typically use for domestic use.
  5. If you have a Rinnai water heater unit that is controlled by a remote control, keep in mind that if the water heater is not used for at least six hours, the default settings will be used, which are 104 degrees Fahrenheit.
  6. The actual temperature of the water will be determined by the distance between the heating source and the faucets or taps. If the distance between the two points is greater, you can overcome the problem by constructing circulating pipes that prevent water from dispersing heat
  8. A mixer or more than one faucet being used at the same time may cause the water heater to fail to supply the desired temperature of water.

How to Use Rinnai Tankless Water Heater

Consider the following before purchasing a Rinnai water heater. How should the unit be operated safely, how should the temperature be changed, and how should the temperature controller be used appropriately for monitoring?

Advanced technology

  1. After your Rinnai water heater has been expertly installed, it is now time to learn how to utilize it properly for dependable, long-lasting, and safe heating for your home or business.
  2. Rinnai tankless heaters are intelligent; they make use of a small computer to provide hot water for as long as it is required, on demand and in continuous supply, and at a temperature that is predetermined.
  3. Because the temperature of the entering water fluctuates from summer to winter, Rinnai regulates the water flow to maintain a consistent temperature of the exiting hot water from the boiler.

The modulating gas valve allows the heater to increase or decrease its power during the heating process, depending on the demand and the temperature that has been set for the heater.Rinnai

Ignition

Tankless units are equipped with direct electronic ignition, which eliminates the need to manually start the fire (since there is no pilot light) because the device instantly ignites the burner when the unit is turned on. The gas will continue to burn as long as there is a need for hot water or as long as the faucet is open.

Venting

Direct venting is used by these units, which means that they draw combustion air from the outside and exhaust flue gases to the outside at the same time.

Manual gas valve

In order to turn on the gas, a manual gas valve positioned near the water heater must be twisted counterclockwise to the fully open position. It was presumed that the valve was closed and not in use.

Isolation valves

It is recommended that the isolation valves provided with the water heater be put on both the cold and hot water lines in order to isolate the unit and perform servicing or maintenance, such as flushing, on the unit.

Water flow

  1. Open a hot water faucet with a flow rate greater than the minimum necessary (0.4 GPM) and wait for a few minutes so that the water can reach the fixture.
  2. The length of the line between the water heater and the faucet determines how quickly you will receive hot water.
  3. A minimum water pressure of 50 PSI is required (with a maximum of 150 PSI), with a suggested water pressure of 60-80 PSI being recommended.

Using the temperature controller to set the temperature

  1. The temperature controller MC-91-2 from Rinnai is built into the front of the unit on the majority of indoor water heaters, although it is not included with the company’s outdoor versions.
  2. The controller is not included with the V53 series of computers.
  3. In addition, the controller makes it simple to monitor and manage the temperature of hot water, and if something goes wrong with the device, its diagnostic system will identify the issue by displaying an error code.

To switch on the electric power to the device, press the ON/OFF button on the unit’s control panel.Make sure the thermostat is set to the proper temperature.Indoor water heaters are supplied with a control panel that is comprised of an LCD display and a number of buttons for operation.

  1. You have the ability to switch the device on or off, as well as increase and decrease the temperature (in F and C).
  2. In response to your pressing of the ″Priority″ button, a green light will illuminate, indicating that your controller is controlling the temperature and that your water heater is ready to use.
  3. Rinnai water heaters operate in the temperature range of 98 F to 140 F, with the factory setting of roughly 120-125 F.
  4. They are available in a variety of sizes.
  5. Additionally, the temperature controller MCC-91-2, which is mostly utilized in commercial applications and has a maximum temperature of 185 F, is available for usage to achieve greater temperatures.
  • A maximum of four controllers can be installed on a single computer.

Controller and diagnostic codes

  1. In addition, the most advanced Rinnai tankless water heaters are capable of diagnosing internal problems and displaying the diagnostic number on the LCD panel.
  2. Diagnostic codes are represented by the numbers 03, 10, 11, and 14, and each code indicates a problem, such as a lack of flame, defective sensors, or a vent obstruction.
  3. Additionally, the controller may provide you with some useful information, such as the flow rate of the water or the temperature of the outgoing water.

Choosing the right temperature

  1. While water is heated over 125 degrees Fahrenheit, it can cause damage, thus extra caution should be exercised when children and the elderly are bathing.
  2. For example, only 3 seconds of hot water immersion at 140 degrees Fahrenheit is required to cause first-degree burns.
  3. It is necessary for the heater to work at a minimum flow rate; otherwise, the device will not operate or will provide hot water at a temperature that is constantly changing.

In addition to using a temperature controller, you may also set and modify the temperature manually.Nonetheless, the default temperature is 120 degrees Fahrenheit, and it may be increased to 140 degrees Fahrenheit by altering the dip switch.Make sure to disconnect the device and drain all of the water if there is a power failure during the cold days.

  1. Providing your water heater is connected to an electric power source, the equipment will not become faulty.

Tankless Water Heater Not Working or Heating? Here’s What to Check First.

  1. Tankless water heaters are energy efficient, have low maintenance costs, and are relatively long-lasting when properly maintained.
  2. However, much like any other item, they are not fully impervious to malfunctions.
  3. They may experience small issues from time to time, such as running out of hot water or the stove not working properly.

Known as demand-type water heaters or instantaneous water heaters, tankless water heaters supply hot water only when it is required.They do not generate the standby energy losses typical with storage water heaters, which can result in significant savings in energy costs.Tankless water heaters heat water immediately, rather than storing it in a storage tank like traditional water heaters do.

  1. Whenever a hot water tap is switched on, cold water is sent into the unit through a pipe from outside.
  2. The water is heated using either a gas burner or an electric element.
  3. Consequently, tankless water heaters are able to provide a continuous supply of hot water.
  4. The need to wait for a storage tank to fill up with adequate hot water is no longer an issue.
  5. The output of a tankless water heater, on the other hand, is limited in terms of flow rate.
  • Check the following items if your tankless water heater isn’t operating up to expectations.
  • What exactly is the problem when you have no hot water in the house but plenty of cold water?
  • If you have a tankless water heater, this is the most typical problem you can anticipate to encounter.
  • In order to get to the source of the problem, you should ask yourself the questions below.

How many appliances am I running at once?

  1. Most likely, if you’re running the dishwasher, doing a load of towels, and taking a shower at the same time, you’re pushing the limitations of your water heater.
  2. Select the hot water activity that you require at this time, turn off the others, then restart your unit to complete the task.
  3. Many times, this is simply due to a slew of faucets being turned on at the same time, such as your shower and the kitchen sink.

For example, having a shower while also running the dishwasher at the same time might cause a tankless water heater to reach its maximum capacity quickly.Alternatively, you may install two or more tankless water heaters that are linked in tandem to handle simultaneous requests for hot water in order to avoid this problem.You may also install separate tankless water heaters for equipment in your house that need a lot of hot water, such as a clothes washer or dishwater.

Am I reaching my minimum flow rate?

  1. Flow rate is defined as the quantity of water (in gallons) that must pass through the tankless unit per minute in order for it to create hot water.
  2. It is likely that the unit is shutting down as a precautionary step if you are requesting less than the minimum flow rate specified.
  3. Increase the amount of water that comes out of your faucet and wait to observe whether the water begins to heat up.

Tankless water heaters must be able to detect the presence of water flow in order to begin operating properly.The majority of models are capable of operating at flow rates as low as 0.5 gallons per minute.This is the lowest minimum flow rate available in the industry, which is a significant advantage.

  1. Tankless water heaters typically supply hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute, depending on the model.
  2. Tankless water heaters that run on natural gas have higher flow rates than those that run on electricity.
  3. Even the largest gas-fired model, on the other hand, may not be able to provide enough hot water for many simultaneous usage in a large family on occasion.

Is something plugged up?

  1. Remove any debris from your vents and air intake tubes to ensure they are not blocked.
  2. Fortunately for you, most tankless water heaters are equipped with warning devices that alert you if an exhaust vent is obstructed in any way or location.
  3. Check to see that everything, both inside and outside, is clear of obstructions, dust bunnies, and other debris.

Burners that are clogged with dirt are another cause of obstruction.Make certain that they are free of debris!

What about my power source?

If you’re using power, make sure your main electrical panel is working properly. It’s possible that anything caused the breaker to trip, necessitating a reset before your tankless water heater would function properly again. If you’re burning gas, check to see that your bill has been paid, that you have propane in your tank, or that your gas valve is fully in the ON position.

Is it cold outside?

  • If your water pipes freeze over during the winter, you may be unable to provide hot water to you or your appliances. Thaw your pipes in a safe and natural manner before attempting to get any hot water again. So what if you’re dealing with the inverse of this situation? If your water is getting too hot, these are the things you should do to cure it: Stop overburdening the system by pressing too many buttons at the same time.
  • Set the temperature of your water heater to around 120 degrees Fahrenheit.
  • Adjust the location of your temperature sensor in order to obtain a more accurate measurement.
  • Inspect and clean the inlet filter on your tankless water heater. Follow the installation instructions provided by the manufacturer for your model. IMPORTANT: Whatever type of tankless water heater you have, be sure to switch it off and allow it to cool completely before trying any DIY repairs
  • once again, make sure to clear any obstructions. Reduced water flow has the potential to cause any heated water to become excessively hot.
  • A malfunctioning heater element is an issue that is exclusive to electrically powered water heaters alone. Electric water heaters can be fitted with one or two heating elements, depending on their size. If a heating element begins to ground out, it will remain on all of the time and overheat to dangerously high temperature levels. Naturally, the end consequence will be uncomfortably hot water – and that’s only to get things started! The heating element will eventually burn itself out totally over time. Then you’ll have no hot water at all until the element is replaced, which might take several hours. It’s the dreaded cold water sandwich, and it’s something that happens all the time in the shower. Here’s what’s most likely taking place: It’s possible that someone else in your house had a shower right before you. Those hot water sensations you’re experiencing at first are due to leftovers from the prior user. The water then becomes lukewarm again while the tankless water heater is re-heating the water to be used in your shower. After that, after the heater has completed its task, you will have hot water once more. If this happens frequently or gets on your nerves, talk to your Northwest Arkansas plumber about if a tiny tank water heater could be a good solution. Using a modest storage tank to provide hot water while the tankless unit is heating up can avoid this cold water sandwich from occurring again. When water from a heater is heated for a few minutes, it then unloads a burst of cold water, after which the water soon returns to being warm again, this is referred to as the cold water sandwich effect. Tankless water heaters are notorious for having this problem. There is some water that remains in a heated state at the mouth of the faucet or other outlets, which means that when someone turns on the faucet or turns on the shower, he will immediately receive some hot water. However, because a tankless heater requires some time to heat up the exchanger, some cold water may pass through the exchanger and reach the consumer during that period. When it comes to electric water heaters, the problem is more prevalent than when it comes to gas-powered water heaters. Due to the fact that gas heats up virtually instantly, but electric heaters may take a minute or two to achieve the appropriate temperature for heating, gas is the preferred fuel for space heating. Your water should be free of contaminants and crystal pure at all times. If your unit is discolored or smells nasty, it’s possible that mold, fungus, or bacteria are developing within it and causing it to malfunction. The smell of ″sulfur″ or rotten eggs is the most prevalent type of foul odor that you might detect. This odor is often caused by sulfate bacteria, which can grow in the tank and cause it to smell. This problem commonly occurs when warm water is kept in the tank for an extended period of time, allowing bacteria to accumulate in the water. The magnesium is broken down by the soft water, which results in the production of sulfate gas within the water heater. Over time, the minerals in our water have a tendency to accumulate in our units. When enough sediment accumulates, the water becomes hazy, yellow, brown, and foul-smelling. You may have an accumulation of rust or broken plumbing within your unit if you detect rusty or rust colored water pouring from your faucets. The use of a pre-made descaling solution or normal distilled white vinegar to flush your tankless water heater should resolve your issue. Getting into the practice of cleaning your tankless water heater at least once every six months is a smart move. If you are aware that you have hard water issues, ask us about water softeners to assist keep your unit in peak operating condition as well. If the rotten egg or unpleasant smell is produced by stagnant water within the tank, it is likely that the water heater will need to be replaced as soon as it is discovered. Some DIY sources may propose draining and flushing the tank, which is not always the case. The stench will most likely remain within the tank even if you are successful in flushing away the germs, and you will continue to have the same problem despite your efforts. It is necessary to ensure that the gas pressure delivered to your tankless heater is enough. Ensure that the gas valve is open and that you have paid your gas bill by double-checking the valve. Inspect any sensors, wiring fuses, and other electrical components to confirm that they have not been damaged or destroyed by the fire. Check to be that there is no dampness or debris on the burners, which might prevent them from igniting. It is impossible for the burner to ignite if the flow rate is too low. Low pressure is one of the most common tankless water heater problems, yet it is also one of the most simple to remedy. The following are the ignition failure codes that have been seen on several tankless brands: Takagi Tankless Water Heater – Error Code 111, 11 or 3 Electric Tankless Water Heater Rinnai – Error Code 11 Takagi Tankless Water Heater – Error Code 111, 11 or 3 Takagi Tankless Water Heater – Error Code 11 Takagi Tankless Water Heater – Error Code 11 Takagi Tankless Water Heater – Error Code 11 Takagi Tankless Water Heater – Error Code 11 Takagi An error code E003 has been encountered by the Navien tankless water heater. Notification of Noritz Tankless Water Heater Error Code 11 The failure of an ignition system on a tankless water heater can occur with any brand and type, regardless of how complex or basic it is. An internal fault with the water heater or an external problem might both cause the failure. Check to see that the gas and water are turned on, and that the power (120 VAC supply) is turned on.
  • Check to ensure that the proper gas type (natural gas or LP) is being used.
  • Check to ensure that the pressure is within specifications.
  • Check to verify that all air has been sucked out of the gas line before and after the installation
  • Make certain that the plumbing is installed appropriately, in accordance with local codes and manufacturer’s instructions.
  • Check to see if the water pressure is within specifications.
  • Make certain that the water is not excessively hard (more than 7 grains), since this might result in sediment build-up.
  • If you live at a higher elevation, check to see if the water heater is adjusted appropriately or according to the manufacturer’s specifications.
  • In the end analysis, is there a problem code?
  1. Typically, water leaks in your water heater are caused by leaky valves and plumbing connections in the system.
  2. If you find a leak, try to locate the source of the leak inside the plumbing system.
  3. If the problem is not immediately apparent, it is recommended that you turn off the water to your water heater and contact a local plumber in your area to come and assess the issue.

11.Attach the purge port valve caps to the purge valves using the hose clamps.Tighten the caps all the way down and securely.

  1. Take care not to overtighten the caps, as this might cause the rubber sealing discs within to crack or shatter.

12. Refer to your water heater’s owner’s handbook for specific advice on how to properly restart the unit. It may be necessary to rotate and open the cold and hot water valves such that they are parallel to the position of the main valve in order to achieve this result.

Pick a sink tap within the house and turn on the hot water gently, allowing enough time for air to travel through the pipe. Make sure to keep the water running until it flows consistently and there is no air escaping (you may recognize this by a slight sputtering sound). Depending on the size of the air pockets, it might take up to 2 or 3 minutes for them to all to escape.

How to Deal with a Delay in Hot Water from a Tankless Water Heaters

  1. Known by a variety of names, including on-demand water heaters and instantaneous water heaters, tankless water heaters have gained popularity.
  2. When you understand how tankless water heaters function in comparison to traditional tank water heaters, you can see why these nicknames are appropriate.
  3. However, the fact is that hot water isn’t literally ″instant″ in the traditional sense.

Because hot water must travel from the heater to the open outlet, there may be a little delay when using tankless water heaters.A homeowner who is concerned about this can attempt a few different approaches, such as building a water recirculation system or a backup water heater adjacent to the afflicted faucet, if the problem is severe.

How a tankless water heater works – and why might there be a delay?

  1. In order to swiftly heat water as it goes through the device, tankless water heaters employ either a strong burner (for natural gas) or a heating element (for electric).
  2. This eliminates the need for the water heater to keep significant volumes of hot water around the clock, as would be the case with a tank unit.
  3. Hot water is released from the tankless water heater and runs via pipes until it reaches an open outlet, such as a faucet, showerhead, or other electrical outlet.

As soon as that outlet is blocked, the flow of hot water from the hot water line is stopped.When the water in the pipe cools down, it may result in a brief burst of cold water when the outlet is opened again before the newly heated water has a chance to travel through the plumbing system.

How to reduce or eliminate the delay

  1. The duration of the delay is controlled by a number of factors, one of which is the distance between the water heater and the output (see illustration).
  2. In other words, the greater the distance traveled by the water, the greater the amount of cold water that must be expelled before the hot water occurs.
  3. Although this wait is usually only a few seconds in most circumstances, there are techniques to make a tankless water heater’s delay less noticeable if it is more than a minor nuisance.

System for recirculation of water – A recirculation system prevents unwanted hot water from accumulating in pipes and becoming chilly.Instead, the technology generates a loop that connects your water heater to an outlet on your wall.As a result, when you turn on the faucet, the hot water that has been waiting in the pipe has already begun to warm up.

  1. The disadvantages of recirculation systems are that they consume more energy and place an additional load on your tankless system’s components.
  2. However, if getting hot water more quickly is vital to you, investing in a recirculation system is a good investment.
  1. The length of the delay is controlled by a number of factors, one of which is the distance between the water heater and the output (see Figure 1).
  2. In other words, the greater the distance traveled by the water, the greater the amount of cold water that must be expelled before the hot water can be obtained.
  3. Although this delay is usually just a few seconds long, there are techniques to lessen the amount of time it takes a tankless water heater to heat water if it is longer or more than a minor annoyance.

A system of recirculation A recirculation system prevents unused hot water from remaining in the pipes and becoming cold.Instead, the technology generates a loop that connects your water heater to an outlet on the wall.Consequently, when you turn on the faucet, the hot water in the pipe that is already waiting to be used is already comfortable to drink.

  1. In addition to consuming additional energy, recirculation systems place additional pressure on your tankless water system.
  2. Recirculation systems, on the other hand, are well worth the investment if you want hot water more quickly.

Safety Issues With Raising Max Temperature

  1. When increasing the hot water temperature in a family, especially if you have small children, exercise caution at all times..
  2. When the water temperature is 140 degrees Fahrenheit, scalding can occur in as little as three seconds.
  3. If your Rinnai tankless water heater does not have a temperature controller and you have young children, the Centers for Disease Control and Prevention (CDC) recommends maintaining the temperature at or below 120 degrees Fahrenheit.

If you have a temperature controller, you may set it to any temperature between 120F and 140F, but not higher than the maximum temperature of 140F, after adjusting the default temperature.

Not Enough Hot Water

Additionally, if you aren’t getting enough hot water after boosting the default temperature, you may want to drop the temperature a little. Lowering the temperature to the level that you really use at the faucet will result in less need to mix in cold water at the faucet, and you will receive more hot water as a result of this.

Can Water Heaters Be Installed Outside: What You Should Know

  • Every family relies on hot water to function properly. Tank water heaters take up a significant amount of room in a home. They are large and hefty, and if a leak occurs, they may cause significant damage. Homeowners are constantly on the lookout for the most effective way to conceal a water heater, even if it means placing it outside. Depending on the circumstances, you may be able to put water heaters outside. Electric and natural gas tank-style water heaters are not intended to be put outside in the elements without protection. Gas tankless water heaters, on the other hand, are available in variants that are put outside. Electric tankless water heaters can also be installed outside, however some form of protection is suggested to keep the device protected from the elements. To elaborate, the decision to put a water heater outside is based on two primary considerations: your geographical location
  • the type of water heater you have

We will examine into tankless and tank-style water heaters that are powered by gas and electricity.

Where to Install a Tankless Gas Water Heater

  1. Because they are small and energy-efficient, tankless water heaters are becoming increasingly popular because they provide an almost limitless supply of hot water.
  2. The primary motivating force is the availability of water on demand.
  3. Tankless gas water heaters are available in both outdoor and interior configurations.

Because the units are customized for each installation technique, you must know which method you will be using before making your purchase.In other words, you can’t put a tankless water heater in the basement and then move it outside.You can identify the difference between the two depending on the amount of venting they produce.

  1. In the front of the tankless outdoor units is a built-in venting system that helps to circulate air.
  2. The top of the indoor tankless water heaters must be equipped with a vent flue attachment.
  3. External tankless water heater types are suitable for outdoor installations, such as on the outside of your home’s outer wall.
  4. On the front of outdoor heaters, there is a built-in vent for ventilation.
  5. Tankless water heaters for indoor use must be installed within a building.
  • They are not as durable as outdoor models when it comes to extreme weather conditions.
  • They are often put within a garage with venting to the outside, which is typically accomplished through an external wall.
  • In most cases, tankless water heaters are installed on the interior side of an outside wall in an indoor installation.
  • Even though it’s unusual, installing a generator in a basement, internal room, or attic is an alternative.
  • A garage is a common site for installing new equipment.
  • The most crucial factor to consider is the adequate venting of exhaust gases to the outside environment.
  • These approaches often comprise the installation of a tankless water heater in conjunction with a recirculation system and a storage tank for hot water.
  • Both outdoor and indoor gas versions generate the same amount of hot water output in gallons per minute (GPM), which is due to the fact that the incoming cold water temperature impacts hot water production more than the location of the unit.
  • Insider’s Suggestion: When installing an outside unit, keep in mind that it should not be positioned within four feet below or to the side of, and one foot above, any door or operable window that may be opened, according to regulation.

This is done in order to keep carbon monoxide from invading the residential area.

Where to Install a Tankless Electric Water Heater

  1. Trash-can-style electric water heaters are becoming increasingly popular, especially in compact places such as tiny homes, flats, condominiums, and recreational vehicles.
  2. Other applications include outdoor places such as pool houses and outdoor showers, where a high volume of hot water is not required at all times.
  3. Electric units are available for installation throughout the home.

However, you must carefully review the specs of these units because they have restrictions and may be quite expensive to operate if there is a high demand for hot water.These units, on the other hand, have proven to be particularly useful in compact areas, such as those with only one bathroom and one kitchen.When it comes to a whole-house solution, I would not suggest them for a household of more than two people.

  1. You have the option of installing an electric unit outside.
  2. We propose that you build a shelter to keep it safe from the rain and cold weather.
  3. Outdoor kitchens, pool houses, and outdoor showers are examples of applications that are ideal.
  4. When compared to tank variants, both gas and electric models offer significantly higher energy efficiency.
  5. Are you looking into purchasing a tankless water heater?
  • Check out our Buyer’s Guide for more information: Was wondering if you could tell me what tankless water heater I needed.

Can You Install a Tank Water Heater Outside

  1. Tank water heaters, whether electric or natural gas, should not be installed in exposed outdoor places without protection.
  2. Installations in the garage, storage area, attic, or other interior locations are recommended.
  3. There are some exceptions to this rule.

It is possible to put them in an outdoor water heater enclosure or a weatherproof shelter if you live in a warm region with no hard winters.In chilly weather, outdoor places are not the ideal choice.Tank versions, in contrast to tankless models, make water heating more difficult and less energy efficient.

  1. An outdoor water heater enclosure, on the other hand, is not required for all tank water heaters.
  2. The diameter of the water heater cannot be more than 30 inches, which eliminates several models from consideration.
  3. Typically, these enclosures can accommodate a water heater with a capacity of up to 80 gallons.
  4. Galvanized steel enclosures are not often recommended since they are not designed with a back and are not typically sealed or insulated, as is the case with aluminum enclosures.
  5. Because it is built up against the house, the steel enclosure does not have a rear.
