There must be:
•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 offvalve 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
Fire and Explosion Hazard
,Use joint compound or tape corn patible with propane
•Leak test before operating heate_:
•Disconnect gas p;ping end
Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum (Propane [LR]) gases
The appliance and its gas connection must be leak tested before placing the appliance in operation.
The appliance and its individual shutoff valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5kPa). It shall be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5kPa).
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.
Breathing Hazard - Carbon Monoxide Gas

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.
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 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 latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54.
