WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
flame to check for a leak. Apply
a noncorrosive leak detection
fluid to all joints. If bubbles form,
there is a leak. Correct all leaks
at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect heater with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping sys-
tem. Pressures in excess of 1/2 PSIG will
damage heater regulator.
2. Cap off open end of gas pipe where equip-
ment shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane supply tank valve or us-
ing compressed air.
4. Check all joints of gas supply piping sys-
tem. Apply a noncorrosive leak detection
fluid to all joints. If bubbles form, there may
be 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 Figure
16).
2. Pressurize supply piping system by either
opening propane supply tank valve or us-
ing compressed air.
3. Check all joints from propane tank to
equipment shutoff valve (see Figure 17).
Apply a noncorrosive leak detection fluid
to all joints. If bubbles form, there is a leak.
4. Correct all leaks at once.

2. Open propane 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 17).
Apply a noncorrosive leak detection fluid
to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Operation, page 16).
Check all other internal joints for leaks.
7. Turn off heater (see Shutting off heater,
page 17).
8. Replace lower front panel.
