Q:Can you put this in an attic
by|May 5, 2024
1 Answer
Answer This Question

A:  Hi Kris and thank you for your question. Fire Hazard – Combustible construction refers to adjacent walls and ceilings and should not be confused with combustible or flammable products and materials. Combustible materials, such as clothing, cleaning materials, or flammable liquids, must not be placed against or next to the water heater. Fire or explosion could occur causing death, personal injury, and/or product damage. A gas-fired water heater should never be installed in a space or room where liquids with flammable vapors are used or stored. Such liquids include gasoline, LP gas (butane or propane), paint, adhesives and their thinners, solvents, or removers. Flammable vapors carry long distances from where they are used or stored. The open flame of the water heater’s main burner can ignite these vapors causing an explosion or fire. NOTICE: Elevating a gas-fired water heater will reduce but NOT eliminate the possibility of lighting the vapor of flammable liquids which may be improperly stored or accidentally spilled. NOTICE: This water heater should not be located in an area where leakage of the heat exchanger or connections will result in damage to the area adjacent to it or to lower floors of the structures. When such areas cannot be avoided, install a suitable catch pan with an adequate drain under the water heater. This drain pan must not restrict the combustion airflow. The following requirements will ensure a safe installation: The water heater must be located in an area where it won’t sustain damage from moving vehicles, flooding, etc. If the water heater is installed in a storage garage, the direct ignition system and main burner should be no less than 18 in. (45 cm) above the garage floor. If the water heater is installed in a repair garage or in a private garage, the direct ignition system and main burner should be no less than 4.5 ft. (1400 mm) above the garage floor. The water heater should be installed as close as possible to the vent termination. This minimizes the vent length and the number of elbows and joints required for venting. The water heater should be installed with the proper venting and exhaust materials suitable for Category III venting. 0" min. (0 mm) Coaxial Vent Pipe and Air Intake 0" min. (0 mm) 0" min. (0 mm) 2829 INSTALLATION INSTRUCTIONS Every vent pipe penetration of a floor or ceiling that is not in a fire-rated shaft requires a fire stop plate. Failure to install and properly vent the water heater to the outdoors as outlined on pages 34 through 45 can result in unsafe operation. Long hot water lines should be insulated to conserve water and energy. The water heater and water lines should be protected from exposure to freezing temperatures. 12" min. (300 mm) 12" min. (300 mm) 0" min. (0 mm) 12" min. (300 mm) 1/2" min. (13 mm) 0" (0 mm) General Fire Stop Plate (as required) • DO NOT install the water heater in areas prohibited by National Fuel Gas Code in U�S� installation or CAN/CSA B149�1 in Canada installation� • DO NOT install the water heater where it is subject to vibrations� • DO NOT install the water heater in a recreational vehicle, mobile home, boat, or other watercraft� • DO NOT install the water heater near vents for heating and cooling� If necessary, maintain a minimum clearance of 4 ft� (1�2 m)� Minimum water heater clearances from combustible and noncombustible construction are as follows: – 1/2 in. (1.3 cm) for sides – 0 in. (0 cm) for rear with support bracket(s) – 12 in. (30 cm) from the bottom, top, and front NOTICE: Preferred maintenance clearance is 24 in. (61 cm) from top, bottom, and front of unit. Minimum clearance around the coaxial vent pipe should meet the specifications listed on the instruction/warning label on the water heater� If no label is found, use the vent manufacturer’s specifications or a minimum clearance of 0 in� (0 cm) around the vent pipe� Please check local codes.

    Q:The photo shows it with an expansion tank. I'm in Los Angeles county. Is it required?
    by|May 4, 2024
    1 Answer
    Answer This Question

    A:  Richard, Thank you for your question. You may want to check with a local installer but we were able to obtain this information for you. The California Plumbing Code (Section 608.3) and the California Mechanical Code (Section 1005.0) requires a thermal expansion tank, or listed equivalent, to be installed to water heating systems to relieve excessive building pressure during the heating process.

      Q:Is this model a condensed unit
      by|Apr 25, 2024
      1 Answer
      Answer This Question

      A:  Hi Rhonda, if you mean is it a high efficiency unit, then it is not. Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens.

          Plan Well Before You Switch to Tankless
          If you are not very handy, leave this to a professional. I had to do a lot of prep work and planning to install this. After that, this was easy to install. The only thing that is tricky is the venting system. The recommended venting system vents at an angle which can be hard to install. The high efficiency is a better option because you can vent with cheaper PVC. One other thing, if you have aerators on you faucets, the flow may not be large enough for the heater to turn on.

            This tankless water heater not good for all buyers. Doesn’t work if you have shared vent in middle of the house, our vent located in the middle, our central heat in the garage up to the roof passing first and second floor. Our previous tank water heater on the first floor connected to the vent in the middle. When we hocked the tankless vent didn’t work, no matter what we did we got error 11, first we thought the gas source small 5/8 , we replaced with bigger ¾ same error 11. Finally after we spent a lot time and money we figured out the vent issue, after we removed 90 degree connected, worked, but that is not possible, if we keep it that way will kill all of us with carbon monoxide also violating the city code. So please think twice before you buy it. One more thing, you really not going to save money on gas, in fact you will use more gas and electric, and loud , we tried it for one day (with vent pipe off) to see if worth to make it work, but not, just not worth the hassle . Sure works if install in wall and vent goes directly outside. Hope home depot will return it, we spent twice of the purchase price, and they know you will spend a lot to make it work.

              Replaced a Rinnai Integrity model that was at least 11 years old. It had been serviced and still couldn't keep up with the simplest of hot water demands. Went with Rheem 8.4gpm unit as Rheem is supposed to do better at altitude (8,600ft in CO) and it keeps up with a shower and laundry and a sink running at the same time. It suits or small household well. Easy enough install since everything was nearby from the previous unit, just had to line up the new exhaust to the wall and work from there. Would have gone to the bigger gpm model if we had a 3rd bath.

                Quality from over protected shipping box. Down to ease of install and operation. Make sure to pre order stainless 3/5 exhaust heat exchanger ducting. Purpose built exhaust required. Have to order before install. My local home Depot doesn't carry exhaust in store. Once installed works perfectly .

                My husband is a pipefitter and so he installed the Tankless Water Heater himself. We had to buy an additional $600 dollars of the 3x5 vent pipe to reroute across the basement . The old unit was vented into the chimney which is a no no for this unit. Except for that, the price was comparable to our old 75 gallon tank water heater but we are looking forward to the expected savings on our gas bill. We do wish they would have these units in stock at our local Home depot. Do have it professionally installed. We think this was a good investment and have had no shortage of hot water for the 7 people in our house. We have 2 laundry rooms 3 bathrooms and we are always doing dishes with no shortage of hot water.

                I have had this water heater for two months now and it is great. My house has three bathrooms with showers. It provides hot water to all three with no drop in temperature or water pressure. This unit replaced a tanked water heater that began to leak. It is in a very small closet attached to the back of the house. Installation went smoothly because I had researched the valves and venting to use. The unit says it needs a 3/4 inch gas line. I am using a 1/2 line without any issues. It runs fine even with the gas dryer and central heat running. It seems the gas pressure in my house is higher than typical. I planned to run a 3/4 inch flex home run from near the gas meter if the 1/2 pipe was inadequate. Be aware that you must use their vent pipe. It is not standard type B vent. The gap between the inner and outer pipe is greater than Type B vent. The outer pipe draws in air for combustion. The inner pipe vents flue gasses. Because the combustion air comes from the out vent pipe, you do not need a vent in your water heater closet door. I used the vertical vent option because the water heater closet already had a hole in the roof for it. It has a horizontal option too I enabled the water saver mode. This entailed taking off the outer panel and flipping a small dip switch. It is supposed to minimize water flow until the set temperature is reached. I did not notice a difference with this enabled.
