IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING. Be sure to read and understand the entire Use and Care Manual before attempting to install or operate this water heater. It may save you time and cost. Pay particular attention to the Safety Instructions. Failure to follow these warnings could result in serious bodily injury or death.
IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING. DANGER! WATER TEMPERATURE SETTING Safety and energy conservation are factors to be considered when selecting the water temperature setting of water heater’s thermostat. Water temperatures above 125°F. can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below. This label is also located on the water heater.
DANGER! LIQUEFIED PETROLEUM (LP - PROPANE OR BUTANE) AND NATURAL GAS MODELS LP and natural gas have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.
IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING. WARNING! For your safety, the information in this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of life. FOR INSTALLATIONS IN THE STATE OF CALIFORNIA California Law requires that residential water heaters must be braced, anchored or strapped to resist falling or horizontal displacement due to earthquake motions.
Installing the water heater. The installation of this water heater must be in accordance with the Manufactured Home Construction and Safety Standard (Title 24, CFR; Part 3280) and the following instructions; instructions supplied with the roof jack assembly, local codes, and utility company requirements governing the installation of water heaters in manufactured homes (mobile homes) and/or in the absence of local codes, the latest edition of The National Fuel Gas Code, ANSI Z223.1.
Installing the water heater. Installation Methods Inspect shipment. — Inspect the water heater for possible shipping damage. Placement of water heater. — Locate the water heater as desired, make certain the minimum clearances outlined in this manual are observed. Combustion and ventilation air. — Air for combustion and ventilation must not be supplied from occupied spaces of the mobile home. Select installation method "A", "B" or "C" from page 9. Method B is recommended for cold climates.
ROOF JACK — This water heater is certified for use with Rheem Models AP12119B, AP12118B, AP12118C, AP12118D roof jacks: Additional information on other Rheem approved and certified roof jacks may be found at www.rheem.com, under “Library”, scroll down to the Technical Service Bulletins Manufactered Housing Series Section and choose Bulletin #1504 or by consulting your distributor.
Installing the water heater. Thermal Expansion Determine if a check valve exists in the inlet water line. Check with your local water utility company. It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve located in the cold water inlet line can cause what is referred to as a “closed water system”.

Installing the water heater. A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, is supplied and must remain in the opening provided and marked for the purpose on the water heater. No valve of any type should be installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.
Gas Supply Check the markings on the water heater’s rating plate to be certain the type of gas being furnished corresponds to that for which the water heater is built. The water heater can be converted from natural gas to LP or vice versa. See the Conversion Instructions section of this manual. The branch gas supply line to the water heater should be clean 1/2″ black steel pipe or other approved gas piping material.
Installing the water heater. WARNING: Failure to install a water heater suitable for the altitude at the location it is intended to serve, can result in improper operation of the appliance resulting in property damage and/or, producing carbon monoxide gas, which could result in personal injury, or death. High Altitude Ratings of gas appliances are based on sea level operation and need not be changed for installations at elevations up to 2,000 feet.

Operating the water heater. CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.

Care and cleaning of the water heater. Draining the Water Heater CAUTION: Shut off gas to the water heater at the thermostat gas cock or manual shut-off valve before draining water. DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.
Venting System Inspection It is recommended the water heater’s internal flue be inspected annually to be certain it is clean by removing the draft hood and flue baffle. When reinstalling the flue baffle make certain it is hung securely by its hanger at the top of the flue way. Remove any scale that may have fallen on the burner or floor shield and reinstall the draft hood.
Before You Call For Service… Troubleshooting Tips Save time and money! Review the charts on the following pages first and you may not need to call for service. Problem Possible Causes Condensation This usually happens when a new water heater is filled for the first time. ● This is normal. After the water in the tank warms up the condensation will disappear. If, however, the condition persists, examine the piping and fittings for possible leaks.
Before You Call For Service… Problem Possible Causes Rumbling noise Scale and sediment in tank. Clean tank. Relief valve producing popping noise or draining Pressure build up caused by thermal expansion to a closed system. This is an unacceptable condition and must be corrected. Contact the water supplier or plumbing contractor on how to correct this. Do not plug the relief valve outlet. Not enough or no hot water Water usage may have exceeded the capacity of the water heater.
