INSTALLATION INSTRUCTIONS
Gas Supply
Leak Testing
WARNING:
Never use an open
flame to test for gas leaks, because death,
personal injury, and/or property damage can result.
The water heater and its gas connections MUST
be leak-tested at normal operating pressures
before the unit is placed in operation. These tests
should also include all factory connections.
Turn on the gas shut-off valve(s) to the water
heater.
Use a soapy water solution to test for leaks at all
the connections and fittings. If bubbles are seen,
it indicates a gas leak that must be corrected.
Contact a qualified service technician.
Pressure Testing the Gas Supply
System
CAUTION:
Install a gas pressure
regulator in the gas supply line. This regulator
should not exceed the maximum supply pressure.
DO NOT use an industrial-type gas regulator.
The water heater and its manual gas shut-off valve
must be disconnected from the gas supply piping
system whenever the pressure testing will exceed
1/2 psi (14 in. w.c. [3.5 kPa]).
The water heater must be isolated from the gas
piping system whenever the pressure testing
will be less than and/or up to 1/2 psi (14 in. w.c.
[3.5 kPa]). Closing the manual gas shut-off valve
will isolate the water heater from the gas piping
system.
