3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.
4.Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Reconnect fireplace and equipment shutoff valve to gas supply. Check reconnected fit- tings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 24).
2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.
3.Check all joints from gas meter to equipment shutoff valve for natural gas or propane/LP supply to equipment shutoff valve for pro- pane/LP (see Figures 25 or 26). Apply non- corrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
