. Leak test before operating heater
• Disconnect gas p!ping and
•A readily accessible manual shut off valve in the gas supply line serving the water heater, and
•A drip leg (sediment trap) ahead of the gas control valve to help prevent dirt and foreign materials from entering the gas control valve.
•A flexible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the water heater. Use a soapy water solution, not a match or open flame. Rinse off soapy solution and wipe dry.
The minimum inlet gas pressure shown on the rating plate is that which will permit firing at the rated input.
Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum (Propane [L,R]) gases.
The appliance and its gas connection must be leak tested before placing the appliance in operation.
The appliance and its individual
Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown in Figures 19 and 20.

If a standard model is installed above 3,300 feet (1,006 m) or a high altitude model is installed above 5,500 feet (1,676 m) the input rating should be reduced at the rate of 4 percent for each 1,000 feet (305 m ) above sea level which requires replacement of the burner orifice in accordance with National Fuel Gas Code ANSI Z223.1IN FPA 54. Contact your local Sears Service Center or local gas supplier for further information.
Failure to replace the standard orifice with a high altitude orifice when installed at elevations above 3,300 feet (1,006 m) or above 5,500 feet (1,676 m) for high altitude model) could result
•Contaminants in gas lines can cause fire or explosion.
•Clean all gas piping before installation.
•Install drip leg in accordance with NFPA 54,
Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the Gas Piping section. Refer to the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
