CAUTION: Use only new,
black iron or steel pipe. Inter
-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to fireplace.
If pipe is too small, undue loss
of volume will occur.
Installation must include an equipment shutoff
valve, union and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up.
NPT tap must be upstream from fireplace
(see Figure 31).
IMPORTANT
: Install main gas valve (equip
-
ment shutoff valve) in an accessible location.
The main gas valve is for turning on or shutting
off the gas to the 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.
FIREPLACE
INSTALLATION
Continued
We recommend that you install a sediment
trap/drip leg in supply line as shown in Figure
31. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping sys
-
tem between fuel supply and fireplace. Locate
sediment trap/drip leg where trapped matter
is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them
from going into fireplace gas controls. If sedi
-
ment trap/drip leg is not installed or is installed
wrong, fireplace may not run properly.

* The equipment shutoff valve may be sup
-
plied with the appliance or you can purchase
it from your retailer.
CONNECTING FIREPLACE TO GAS
SUPPLY
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• sealant (resistant to propane/LP gas, not
provided)
1. Open lower louver door panel by gently
pulling forward.
2. Route flexible gas line (provided by in
-
staller) from equipment shutoff valve to
fireplace. Route flexible gas supply line
through one of the access holes on side
of fireplace.
3. Attach flexible gas line from gas supply to
control valve (see Figure 32, page 23).
4. Check all gas connections for leaks. See
Checking Gas Connections,
page 23.
