CHECKING GAS CONNECTIONS
WARNING: Test all gas pip-
ing and connections, internal
and external to unit, for leaks
after installing or servicing. Cor-
rect all leaks at once.
WARNING: Never use an
open ame to check for a leak.
Apply a noncorrosive leak
detection fluid to all joints.
Bubbles forming show a leak.
Correct all leaks at once.
CAUTION: Make sure exter-
nal regulator has been installed
between propane/LP supply and
replace. See guidelines under
Connecting Fireplace to Gas
Supply, page 15.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect replace with its main gas
valve (control valve) and equipment shut-
off valve from gas supply piping system.
Pressures in excess of 1/2 psig will dam-
age replace 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 system.
Apply noncorrosive leak detection uid 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 ttings for leaks.

Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see
Figure 18).
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 19 and 20).
Apply noncorrosive leak detection uid to
all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
