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 noncorrosive leak detection fluid 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 fit- tings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 13).
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 sup- ply to equipment shutoff valve for propane/LP (see Figure 14 or 15). Apply 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 13).
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 heater is in the OFF position.
4.Check all joints from equipment shutoff valve to control valve (see Figure 14 or 15). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light heater (see Operating Heater). Check all other internal joints for leaks.
