GENERAL INFORMATION This gas-fired water heater’s design is certified by CSA International under the American National Standard Z21.10.1 and CSA 4.1-M, most current editions at the time of manufacture. This water heater must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).
General Information continued- A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water. If this should happen, an alternative anode may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank.
Installation (Locating The Water Heater) continued- Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals.
Installation (Locating The Water Heater) continued- WARNING DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING: Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in the detection of the gas. Most people recognize this odor as a “sulfur” or “rotten egg” smell. Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.
Minimum Clearances WARNING Failure to adhere to these installation and operating instructions may create a hazard to life and property and will nullify the warranty. This installation must allow access to the front of the water heater and adequate clearance must be provided for servicing and operating this water heater. The water heater may be installed on either a combustible or noncombustible floor.

Vent Pipe Preparation and Joining Most failures in vent systems result from improper preparation and joining of pipe and fittings. The guidelines below must be followed when installing the venting system. If you have any question about the application or installation of the venting system, contact the vent pipe manufacturer, supplier, or your plumbing professional. 1) Specific cleaners, solvents, primers and cements are available for PVC, CPVC, and ABS pipe.
Vent Pipe Preparation and Joining continued- d) Cementing must be done quickly to avoid over-drying before joining. i) Apply one coat to the outside end of the pipe at a width slightly greater than the depth of the socket. ii) Apply a coat around the inside of the fitting socket. iii) Apply a second coat around the end of the pipe. 4) Joining a) Joints should be made immediately after cement is applied. b) After fully inserting pipe into fitting socket, hold joint together for about 15 to 20 seconds.
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.
Installation (Combustion Air Supply) continued- All Air From Inside the Building: The confined space must be provided with two permanent openings communicating directly with an additional room(s) of sufficient volume so that the combined volume of all spaces meets the criteria for an unconfined space. The total input of all gas utilization equipment installed in the combined space must be considered in making this determination. Each opening must have a minimum free area of 1 square inch per 1000 BTU (6.
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 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 B149.2 Propane Installation Code (Latest Edition). The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. See the rating plate and gas valve for the manifold pressure and gas type.
Electrical Connections All electrical wiring and connections must be in accordance with the National Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical Code C22.1 (latest edition) and any local codes which may apply. The water heater must be electrically grounded. If a flexible line cord and plug is permitted by local code, then provide a (3) three wire grounding type receptacle within 6 feet (1.9 m) of the water heater and use the flexible cord provided.

GENERAL OPERATION WARNING Water heaters are heat producing appliances. To avoid damage or injury there must be no materials stored against the water heater or vent-air intake system, and proper care must be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
Lighting and Shutdown instructions 29
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. Figure 7 DANGER Hotter water increases the risk of scald injury.
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. To avoid damage or injury there must be no materials stored against the water heater or vent-air intake system, and proper care must be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
Maintenance continued- 5. Annually remove the inner door and main burner assembly to clean orifices and related parts of any dirt or other foreign material. Inspect the burner ports for obstructions or debris and clean with a wire brush as needed. Wire brush and/or vacuum clean the combustion chamber as needed to remove scale deposits and debris. NOTE: It is imperative for proper operation of the water heater that the inner door be replaced in the original location.
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. WARNING Do not run out of propane gas. Damage to the water heater may occur. 6. At least once a year, check the combination temperature and pressure relief valve to insure that the valve has not become encrusted with lime.
