INSTALLING GAS PIPING TO
FIREPLACE LOCATION
Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional A.G.A. design-certified
manual shutoff valve from your dealer. See
Accessories, pages 26 and 27.
NOTICE: A qualified service per-
son must connect fireplace to
gas supply. Follow all local codes.
WARNING: Never connect
fireplace to private (non-utility)
gas wells. This gas is commonly
known as wellhead gas.
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
pressure will occur.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 29. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap 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 is not installed or is installed
wrong, fireplace may not run properly.
INSTALLATION
Continued
Installation must include a manual 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 29).
Check your building codes for any special
requirements for locating manual shutoff
valve to fireplaces.
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
Installation Items Needed
• 5/16" hex socket wrench or nut-driver
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not
provided)
1. Remove fireplace screen. Remove two
screws that hold fireplace screen in
place for shipping. These screws are
located near top of screen. Discard
screws. Lift fireplace screen up and pull
out to remove.
2. Remove screws that attach log base
assembly to fireplace (see Figure 30,
page 15). Carefully lift up log base as-
sembly and remove from fireplace (see
Figure 30, page 15).
Note: If adding the G8000 series brick liner
accessory, install it now. Follow instruc-
tions in G8000 accessory kit.
CONNECTING FIREPLACE
TO GAS SUPPLY
CAUTION: Do not pick up log
base assembly by burners. This
could damage burners. Only
handle base by grates.
3. Route flexible gas line (provided by
installer) from manual shutoff valve to
fireplace. Route flexible gas supply line
through one of the access holes.
