Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 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 compressed air.
3. Check all joints from gas meter for natural
gas (see Figure 16)) or propane/LP supply
tank for propane/LP to equipment shutoff
valve (see Figure 17). Apply a noncor-
rosive 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
15).
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
16 or 17). 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 15).
Check all other internal joints for leaks.
7. Turn off heater (see
To Turn Off Gas to
Appliance
, page 16).
8. Replace front panel.
