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 / 600 meter. Unit not recommended for elevations in excess of 2,000 feet / 600
meter.
