Vent Pipe Preparation and Joining continued- a) CLEANERS, SOLVENTS, PRIMERS AND CEMENTS ARE FLAMMABLE. Do not store or use these materials near heat or open flame, or in the vicinity of other appliances. 2) Use proper cutting, deburring and applicator tools to ensure proper preparation and joining of pipe and fittings. a) Cutting Tools i) A square cut must be achieved with a miter box saw or pipe cutter to ensure a proper mating with the female.
Combustion Air Supply WARNING Liquefied petroleum gases/propane gases are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor. IF YOU SMELL GAS: DO NOT try to light any appliance. DO NOT touch any electric switch; do not use any telephone in your building.
Combustion Air Supply continued- Each opening must have a minimum free area of 1 in2/1000 BTU/hr (2200 mm2/kW) of the total input rating of all gas utilization equipment in the confined space, but not less than 100 in2 (0.06 m2). One opening must be within 12 in (31 cm) of the top and one within 12 in (31 cm) of the bottom of the enclosure.
Water Connections NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater. After the pressure has been relieved, close the faucet. The COLD water inlet and HOT water outlet are identified on the top of the water heater.
Water Connections continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials as meeting the requirements of the Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, A
Water Connections continued- WARNING Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance which is connected to the hot water system.
Gas Connections WARNING Prior to connecting the gas supply line to a gas fired water heater, ensure that the gas supply line does not have moisture/water or dirt/scale inside the gas line. Commonly this check is done at the lowest point in the gas distribution system prior to gas burning appliances. The gas supply lines must meet all requirements of the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.
Gas Connections continued- CAUTION The water heater and individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa).

Lighting & Shutdown Instructions 27
Thermostat Adjustment The thermostat dial is adjusted to its lowest setting when shipped from the factory. When adjusting the thermostat, it should be remembered that lower temperature settings are more energy efficient. To adjust the thermostat, turn the dial clockwise until the minimum acceptable temperature is set. It is suggested that the starting point setting not exceed the 120°F (49°C) or “HOT” setting on the thermostat.
Burner Flame Check Steel Burner: These models are equipped with self-adjusting air mixture and do not have an adjustable air shutter (see Figure 8). At periodic intervals a visual check of the main burner and pilot flames should be made to determine if they are burning properly. The main burner flame should light smoothly from the pilot. Figure 8 WARNING DO NOT run out of propane gas. Damage to the water heater may occur. MAINTENANCE WARNING Water heaters are heat producing appliances.
Maintenance continued- The following maintenance should be performed by a qualified service technician at the minimum periodic intervals suggested below. In some installations, the maintenance interval may be more frequent depending on the amount of use and the operating conditions of the water heater. Regular inspection and maintenance of the water heater and vent-air intake system will help to insure safe and reliable operation. 1. Annually check the operation of the thermostat. 2.
Maintenance continued- Do not block or in any way restrict jacket air inlet slots located at the bottom front of the water heater. Do not operate water heater with jumpered, altered, loosely tightened or absent controls and/or components. Do not operate water heater with replacement controls and/or components which are not exact duplicates of original equipment.
Maintenance continued- WARNING When lifting lever of the combination temperature and pressure relief valve, hot water will be released under pressure. Be careful that any released water does not result in bodily injury or property damage. 6. At least once a year, check the combination temperature and pressure relief valve to ensure that the valve has not become encrusted with lime. Lift the lever at the top of the valve several times until the valve seats properly without leaking and operates freely.
