4. Check all joints of gas supply piping sys-
tem. Apply a noncorrosive leak detection
fluid to all joints. If bubbles form, there may
be a leak.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 17).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve
for propane/LP gas or opening main gas
valve located on or near gas meter for
natural gas or using compressed air.
3. Check all joints from gas meter (natural
gas installations, see Figure 18) or from
propane/LP tank (propane/LP gas installa-
tions, see Figure 19) to equipment shutoff
valve. Apply a noncorrosive leak detection
fluid to all joints. If bubbles form, there is
a leak.
4. Correct all leaks at once.
