Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect burner system and its
individual manual shutoff valve from
gas supply piping system. Pressures in
excess of 1/2 psig (3.5 kPa) will
damage burner system gas regulator.
2. Cap off open end of gas pipe where
manual shutoff valve was connected.
3. Pressurize supply piping system by ei-
ther opening propane/LP supply tank
valve for propane/LP gas burner sys-
tem or opening main gas valve located
on or near gas meter for natural gas
burner system, or using compressed air.
4. Check all joints of gas supply piping
system. Apply commercial leak test so-
lution to all gas joints. Bubbles forming
show a leak. Correct all leaks at once.
5. Reconnect burner system and manual
shutoff valve to gas supply. Check re-
connected fittings for leaks.
