Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 14).
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 15) or propane/LP supply tank for propane/LP gas, to equipment shutoff valve (see Figure 16). 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 14).
2.For natural gas open main gas valve located 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 15 or 16). Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light heater (see Operating Heater, page 13). Check all other internal joints for leaks.
7.Turn off heater (see To Turn Off Gas to Appli- ance, page 14).
8.Replace front panel.
