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
shutoffvalve 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 offsoapy solution and wipe dry.

feet above sea level.
Ifa standard model is installed above 3,300 feet or a high altitude
model is installed above 5,500 feet, the input rating must be
reduced at the rate of 4 percent for each 1,000 feet above sea level.
