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:
If inlet gas pressure is out of allowable range [4.0”
w.c. (1.0kPa) – 10.5” w.c. (2.6kPa)] for Natural Gas,
or [8.0” w.c. (2.0kPa) – 13.0” w.c. (3.2kPa)] for LP
gas, a gas pressure regulator must be installed to
maintain the allowable inlet gas pressure.
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.
