2. Pressurize supply piping system by either opening propane/LP
supply tank valve for propane/LP gas fireplace or opening main
gas valve located on or near gas meter for natural gas fire-
place, or using compressed air.
3. Check all joints from propane/LP supply tank or gas meter to
equipment shutoff valve (see Figure 34 for propane/LP or Figure
35 for natural gas). Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak. Correct all leaks at once.
