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 appliance and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 10).
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 to equipment shutoff valve for natural gas or propane/LP supply to equipment shutoff valve for propane/LP (see Figure 11). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
Pressure Testing Appliance Gas Connections
1.Open equipment shutoff valve (see Figure 10).
2.Open main gas valve located on or near gas meter for natural gas or open propane/LP supply tank valve.
3.Make sure control knob of appliance is in the OFF position.
4.Check all joints from equipment shutoff valve to gas control (see Figures 11 and 12). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light appliance (see Operating Appliance, pages 11 through 13). Check all other internal joints for leaks.
7.Turn off appliance.
