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 noncorrosive leak detec-
tion fluid to gas joints. Bubbles form-
ing 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.
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 11.

CONNECTIONS
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 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, page 13). Apply noncorro-
sive leak detection fluid to gas joints.
Bubbles forming show a leak.
4. Correct all leaks at once.

Connections
1. Open equipment shutoff valve (see
Figure 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,
page 13). Apply noncorrosive leak de-
tection fluid to gas joints. Bubbles
forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Operating Heater,
pages 14 through 16). Check all other
internal joints for leaks.
7. Turn off heater (see To Turn Off Gas to
Appliance, page 15).
