Most jurisdictions also require an additional pressure or leakage test performed after the construction is
c
ompleted and finished interior walls are in place. The leakage test procedure is generally performed by
the gas utility at the time of setting their meter. This test is performed to assure no damage was done to
the tubing during the closing-in construction process, and is typically required before gas service is initiated.
Appliance Connection Leakage Check Procedure
After the final pressure test, inspection and final construction is complete (finished interior walls) connect the appli-
ances to the tubing system. This connection can be made using a stainless steel flexible connector for movable
appliances such as a dryer or range, or with CSST tubing, or rigid black pipe for fixed appliances. Turn the gas on at
the meter and inspect for leakage before operating the appliances.
a) Connections made at the appliances should be leak checked with a chloride-free bubble solution.
b) Before placing the appliances in operation, the tubing system should be purged. This displaces the air in
the system with fuel gas. Be sure to vent into a well-ventilated area.
N
OTE: Leak test solutions may cause corrosion to some types of material in the gas tubing system, be sure to water rinse after the test and thor-
oughly dry all contacted material. Also, the vent limiter should not be leak tested with a liquid test solution. This will contaminate the internal ball
c
heck mechanism or plug the breathing hole, resulting in erratic regulator operation.
