Leak testing
WARNING:
Never use an open flame to test for gas leaks, as property
damage, personal injury, or death could result.
The water heater and its gas connections must be leak tested at normal operating
pressures before it is placed in operation.
● Turn on the gas shut-off valve(s) to the water heater.
● Use a commercial leak detector or soapy water solution to test for leaks at all
connections and fittings. Bubbles indicate a gas leak that must be corrected.
All connections should also be leak tested after the water heater is placed in
operation.
Pressure testing the gas supply system
WARNING: Install a gas pressure regulator, in the gas supply line,
which does not exceed the maximum supply pressure. DO NOT use an
industrial type gas regulator.
The water heater must be isolated from the gas piping system by closing the
manual gas shut-off valve during any pressure testing of the gas supply piping at
pressures equal to or less than 1/2 psi (14’w.c.).
High altitude
Ratings of gas appliances are based on sea level operation and need not be
changed for installations at elevations up to 2,000 feet. Unit not recommended for
elevations in excess of 2,000 feet.
