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.

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[...]

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.
