FIREPLACE INSTALLATION
Continued
IMPORTANT
: Install main gas valve (equip
-
ment shutoff valve) in an accessible location.
The main gas valve is for turning on or shutting
off gas to appliance.
Check your building codes for any special
requirements for locating equipment shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could
result in clogged fireplace valves.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.
We recommend that you install a sediment
trap/drip leg in supply line as shown in Figure
20, page 15. Locate sediment trap/drip leg
where it is within reach for cleaning. Install
in piping system between fuel supply and
fireplace. Locate sediment trap/drip leg where
trapped matter is not likely to freeze. A sedi
-
ment trap traps moisture and contaminants.
This keeps them from going into fireplace
gas controls. If sediment trap/drip leg is not
installed or is installed wrong, fireplace may
not run properly.
CONNECTING FIREPLACE TO GAS
SUPPLY
Installation Items Needed
• 3/4" and a 7/8" open end wrench or adjust
-
able wrench
• sealant (resistant to propane/LP gas, not
provided)
1. Remove lower louver door panel by lifting
up until disengaged. Swing forward and
out of locating slots at bottom.
2. Route flexible gas line (provided by in
-
staller) from equipment shutoff valve to
fireplace. Route flexible gas supply line
through one access hole on each side of
fireplace cabinet.
3. Attach flexible gas line from gas supply
to the 1/2" flare fitting provided on control
valve (see Figure 21).
4. Check all gas connections for leaks (see
Checking Gas Connections
).

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
noncorrosive leak detection fluid
to all joints. Bubbles forming show
a leak. Correct all leaks at once.
PRESSURE TESTING GAS SUPPLY
PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1. Disconnect fireplace and its individual
equipment shutoff valve from gas supply
piping system. Pressures in excess of 1/2
psig (3.5 kPa) will damage fireplace gas
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 fireplace or opening
main gas valve located on or near gas
meter for natural gas fireplace 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. Correct all leaks at once.
5. Reconnect fireplace and equipment
shutoff valve to gas supply. Check recon
-
nected fittings for leaks.
