18 L.P.G. (Bottled Propane) Models Liquefi ed petroleum gas is over 50% heavier than air and in the occurrence of a leak in the system, the gas will settle at fl oor level. Basements, crawl spaces, skirted areas under mobile homes (even when ventilated), closets and areas below ground level will serve...

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 condens...

20 MAINTENANCE OF YOUR WATER HEATER 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.
