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 money. 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 a water heater’s gas control. 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. This water heater must be installed in accordance with these instructions, local codes, utility company requirements, and/or in the absence of local codes, use the latest edition of the American National Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400 N. Capitol Street NW, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54.
Installing the water heater. Inspect Shipment Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the type of gas supplied corresponds to the water heater requirements. Combustion and Ventilation Air Ventilation (ambient) air temperature must be 100°F or less. Proper operation of the water heater requires air for combustion and ventilation. Provisions for combustion and ventilation air must comply with referenced codes and standards.

Supplemental instructions for gas water heaters installed in potable water/space heating applications. Local codes or plumbing authority requirements may vary from the instructions or diagrams provided in this manual and take precedent over these instructions.
Lighting the water heater. Before operating this water heater, be sure to read and follow the instructions on the label pictured below and all other labels on the water heater, as well as the warnings printed in this manual. Failure to do so can result in unsafe operation of the water heater resulting in property damage, personal injury, or death. Should you have any problems reading or following the instructions in this manual, STOP, and get help from a qualified person.
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.
Operating the water heater cont. Water Temperature Setting… The following is additional information which aid in determining a safe working temperature to meet each household need. Maximum water temperatures occur just after the burner has shut off. To determine the water temperature, turn on a hot water faucet and place a thermometer in the water stream.
Sequence of Operation… 1. During initial start-up or a call for heat, the control will verify the vacuum switch is open. 2. Once the control verifies the blower vacuum switch is open, the control will energize the blower motor for the pre-purge sequence (approximately 5 seconds). 3. The control will verify the blower vacuum switch has closed, ensuring that the blower is functioning properly and that the venting system is not blocked. 4.
Care and cleaning of the water heater. Draining the Water Heater ! CAUTION: Shut off gas to the water heater at the gas control (thermostat) gas cock or manual shut-off valve before draining water. ! DANGER: Before manually operating the temperature and pressure 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.
Housekeeping ! DANGER: Combustible materials, such as clothing, cleaning materials, or flammable liquids, etc., must not be placed against or next to the water heater. Visually inspect the pilot. To ensure sufficient ventilation and combustion air supply, proper clearances must be maintained. When installed in a closet, DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater.
Care and cleaning of the water heater Vacation and Extended Shut-Down NOTICE: Refer to the Hydrogen Gas Caution in the Operating Instructions. If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent a build-up of dangerous hydrogen gas. water heater’s operation and controls should be checked by qualified service personnel. Make certain the water heater is completely filled again before placing it .
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. This water heater incorporates a combustion shut off device that shuts the operation of the water heater down if undesirable combustion conditions occur, such as the presence of flammable vapors or blockage of the combustion air inlet openings. Please contact a Qualified Service Technician if this occurs.
