Section 6: Pressure / Leakage Testing
6.3 Appliance Connection Leakage Check Procedure
After the final pressure test, inspection and final construction is complete (finished interior walls), connect the appliances to
the system. is connection can be made using an approved flexible connector for movable appliances, or with FlashShield™
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. Leak check solutions
must be chloride-free or be labeled as non-corrosive to stainless steel, or be labeled as non-corrosive.
b) Before placing the appliances in operation, the tubing system should be purged. is displaces the air in the system with
fuel gas. Be sure to vent into a well-ventilated area.
NOTE: Leak test solutions may cause corrosion in some types of material in the gas tubing system, be sure to water
rinse after the test and thoroughly dry all contacted material. Also, the vent limiter should not be leak tested with a
liquid test solution. is will contaminate the internal ball check mechanism or plug the breathing hole, resulting in
erratic regulator operation.
NOTE: Near maximum allowable pressure test levels listed on the FlashShield™ specification sheets, the tubing may
move/distort which can affect tubing supports. Once the pressure is released the tubing should return to relatively the
same position. Use caution when pressure testing and do not exceed the maximum test pressure.
