NOTICE: Most building codes
do not permit concealed gas
connections. A flexible gas line
is provided to allow accessibility
from the fireplace (see Figure 20).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping
and connections, internal and
external to unit, for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open flame to check for a leak.
Apply a noncorrosive leak detec-
tion 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
fireplace. See guidelines under
Connecting Fireplace to Gas
Supply, page 14.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect fireplace 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 fireplace 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.
