CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
fireplace. See guidelines under
Connecting to Gas Supply,
page 13.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
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 piping
system. 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/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 sys-
tem. Apply noncorrosive leak detection
fluid to all joints. Bubbles forming show a
leak.
5. Correct all leaks at once.
6. Reconnect fireplace and equipment
shutoff valve to gas supply. Check recon-
nected fittings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Fig-
ure 17).
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 to equip-
ment shutoff valve for natural gas or pro-
pane/LP supply to equipment shutoff valve
for propane/LP (see Figures 18 or 19).
Apply noncorrosive leak detection fluid to
all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
PRESSURE TESTING FIREPLACE GAS
CONNECTIONS
1. Open equipment shutoff valve (see Fig-
ure 17).
2. Open main gas valve located on or near
gas meter for natural gas or open pro-
pane/LP supply tank valve.
3. Make sure control knob of fireplace is in
the OFF position.
4. Check all joints from equipment shutoff valve
to control valve (see Figures 18 or 19). Apply
noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light fireplace (see Operation, page 18).
Check all other internal joints for leaks.
7. Turn off fireplace (see To Turn Off Gas to
Appliance, page 19.
