3 INST ALLING YOUR GAS W A TER HEA TER Important Information About This W ater Heater This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a fl ammable vapor ignition incident. New technology used in meeting these standards makes this product more sensitive to installation errors or improper installation[...]

4 Location Requirements The Flame Lock™ Safety System is designed to reduce the risk of flammable vapor-related fires. The patented system protects your family by trapping the burning vapors within the water heater combustion chamber through the special flame-trap. The burning vapors literally “burn themselves out” without escaping back into [...]

5 IMPORT ANT : The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water , the tank will eventually leak after an extended period of time. Also any external plumbing lea[...]

6 Gas Supply Gas Requirements IMPORT ANT : Read the data plate to be sure the water heater is made for the type of gas you will be using in your home. This information will be found on the data plate located near the gas control valve/thermostat. If the information does not agree with the type of gas available, do not install or light. Call your de[...]

10 V ent Pipe System This water heater uses a non-direct, single-pipe vent system to remove exhaust gases created by the burning of fossil fuels. Air for combustion is taken from the immediate water heater location or is ducted in from the outside (see “Combustion Air Supply and V entilation”). This water heater must be properly vented for the [...]

11 Chimney Connection IMPORT ANT : Before connecting a vent to a chimney , make sure the chimney passageway is clear and free of obstructions. The chimney must be cleaned if previously used for venting solid fuel appliances or fireplaces. Also consult local and state codes for proper chimney sizing and application or , in the absence of local and s[...]

12 W ater System Piping Piping Installation Piping, fittings, and valves should be installed according to the installation drawing (Figure 13). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. W ater supply pressure should not exceed 80% of the working pressure of the water heate[...]

13 Closed System/Thermal Expansion Periodic discharge of the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure reducing valve. This will create a closed water system. During the heating cycle of the wat[...]

Protected from freezing temperatures. □ Proper clearances from combustible surfaces maintained and not installed directly on a car[...]

16 OPERA TING YOUR W A TER HEA TER Lighting Instructions Read and understand these directions thoroughly before attempting to light or re-light the pilot. Make sure the viewport is not missing or damaged. (See Figure 23) Make sure the tank is completely filled with water before lighting the pilot. Check the data plate near the gas control valve/the[...]

17 Checking the Draft After successfully lighting the water heater , allow the unit to operate for 15 minutes and check the drafthood relief opening for proper draft. Make sure all other appliances in the area are operating and all doors are closed when performing the draft test. Pass a match flame around the relief opening of the drafthood. A stea[...]

19 Operational Conditions Condensation Moisture from the products of combustion condenses on the tank surface and the outside jacket of the water heater and forms drops of water which may fall onto the burner or other hot surfaces. This will produce a “sizzling” or “frying” noise. NOTE: This condensation is normal and should not be confused[...]

20 MAINTENANCE OF YOUR W A TER HEA TER Draining and Flushing It is recommended that the tank be drained and flushed every 6 months to remove sediment which may build up during operation. The water heater should be drained if being shut down during freezing temperatures. T o drain the tank, perform the following steps: 1. T urn off the gas to the wa[...]
