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 gas regulator (Thermostat-Controlled
Models) or to gas control valve (Remote-
Ready Models) (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 19).
Check all other internal joints for leaks.
7. Turn off fireplace (see
To Turn Off Gas
to Appliance
, page 20 for Thermostat-
Controlled Models or page 22 for Remote-
Ready Models).
