Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 15).
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 com-
pressed air.
3. Check all joints from gas meter for natural gas (see Figure 16)
or propane/LP supply tank for propane/LP gas, to equipment
shutoff valve (see Figure 17). Apply a noncorrosive leak de-
tection 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 15).
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 16 or 17). Apply a noncorrosive leak
detection fluid to all joints. Bubbles forming show a leak.
