flame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. Bubbles forming show
a leak. Correct all leaks at once.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 27).
2. Pressurize supply piping system by ei-
ther using compressed air or opening
propane/LP supply tank valve.
3. Check all joints from propane/LP sup-
