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 con-
nected.
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 mixture of liquid soap
and water 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.

CONNECTIONS
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.
Test Pressures Equ al 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 mixture of liquid
soap and water 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 gas control (see Figure 15).
Apply mixture of liquid soap and wa-
ter 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
