Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2
psig will damage heater regulator.
2. Cap off open end of gas pipe where
equipment shutoff valve was connected.
3. Pressurize supply piping system by ei-
ther using compressed air or opening
propane/LP supply tank valve.
4. Check all joints of gas supply piping
system. Apply a noncorrosive leak de-
tection fluid to gas joints. Bubbles
forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment
shutoff valve to gas supply. Check re-
connected fittings for leaks
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 ei-
ther using compressed air or opening
propane/LP supply tank valve.
3. Check all joints from propane/LP sup-
ply tank to equipment shutoff valve (see
Figure 16). Apply a noncorrosive leak
detection fluid to gas joints. Bubbles
forming show a leak.
4. Correct all leaks at once.
Pressure Testing Heater Gas
Connections
1. Open equipment shutoff valve (see Fig-
ure 15).
2. 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 control valve (see Figure 16).
Apply a noncorrosive leak detection
fluid to gas joints. Bubbles forming
show a leak.
5. Correct all leaks at once.
6. Light heater (see Operating Heater,
pages 15 and 16). Check all other in-
ternal joints for leaks.
7. Turn off heater (see To Turn Off Gas to
Appliance, page 16).
WARNING: Never use an open
flame to check for a leak. Apply a
noncorrosive leak detection fluid
to all joints. Bubbles forming show
a leak. Correct all leaks at once.
WARNING: Test all gas pip-
ing and connections for leaks
after installing or servicing. Cor-
rect all leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
heater. See guidelines under
Con-
necting to Gas Supply
, page 12.
