• 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.
