2.Cap off open end of gas pipe where equip- ment shutoff valve was connected.
3.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.
4.Check all joints of gas supply piping system. Apply a commercial leak detection solution to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Reconnect heater 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 Fig- ure 16).
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 for natural gas (see Figure 17)) or propane/LP supply to equipment shutoff valve (see Figure 18). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
4.Correct all leaks at once.
Pressure Testing Heater Gas Connections
1.Open equipment shutoff valve (see Figure 16).

2.For natural gas, open main gas valve lo- cated on or near gas meter. For propane/ LP gas, open propane/LP supply tank valve.
3.Make sure control knob of heater is in the OFF position.
4.Check all joints from equipment shutoff valve to thermostat gas valve (see Figure 17 or 18). Apply a noncorrosive leak de- tection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light heater (see Operation page 14). Check all other internal joints for leaks.
7.Turn off heater (see To Turn Off Gas to Appliance, page 15).
8.Replace front panel.
