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.

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.
