Leak Testing

Leak Testing
Gas pressures to the appliance controls must never exceed 14 inches W.C. (1/2 PSI).
Supply pressures greater than 14" W.C. can damage the controls, resulting in personal
injury, property damage, or death.
Use a soap solution or equivalent for leak testing. Leak testing solution must be non-corrosive, and be
rinsed off immediately after the leak test. Never test for leak with an open flame. Failure to comply could
result in personal injury, property damage or death.
Always leak test final gas assembly for gas leaks according to the procedures outlined in NFPA 54 and
all local codes and/or Standards.
For leak testing on pressures below 1/2 PSI
Before leak testing, close the field installed manual shut off valve shown on Figure 3.29 on the supply
line to isolate the gas valve from the pressure. NOTE: All factory installed gas connections have passed
an approved leak test.
For leak testing on pressures above 1/2 PSI
When leak testing with pressures above 1/2 PSI (14 inches W.C.), the unit must be isolated from the
supply pipe. Close the field installed manual shut off valve, disconnect the supply line to the unit, and
temporarily cap the supply line for testing purposes.
WARNING
!
Testing for gas leaks with an open flame or other sources of ignition may lead
to a fire or explosion and cause serious injury or death. Test in accordance
with NFPA or local codes.
