Installation Items Needed
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 branch sup-
port to fireplace (see Figure 25). Care-
fully lift up branch support and remove
from fireplace (see Figure 25).
3. Route flexible gas line, included, from
fireplace control to equipment shutoff
valve through side or rear access holes
in outer casing.
NOTICE: Most building codes do
not permit concealed gas con-
nections. A flexible gas line is
provided to allow accessibility
from the fireplace (see Figure 26).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
4. Apply pipe joint sealant lightly to male
threads of gas connector attached to
flexible gas line/equipment shutoff
valve (see Figure 26).

CAUTION: Use pipe joint seal-

We recommend that you install a sediment
trap in supply line as shown in Figure 24,
page 14. Locate sediment trap where it is
within reach for cleaning. Install in piping
system between fuel supply and heater.
Locate sediment trap where trapped matter
is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them
from going into fireplace controls. If sedi-
ment trap is not installed or is installed
wrong, fireplace may not run properly.

5. Check all gas connections for leaks. See
Checking Gas Connections, page 16.
6. Replace branch support back into fire-
place. Feed flexible gas line into fire-
place base area while replacing branch
support. Make sure the entire flexible
gas line is in fireplace base area. Reat-
tach branch support to fireplace with
screws removed in step 2.
CAUTION: Avoid damage to
regulator. Hold gas regulator with
wrench when connecting it to gas
piping and/or fittings.
