Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Remove screws that attach branch support to
fireplace (see Figure 22). Carefully lift up
branch support and remove from fireplace (see
Figure 22).
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 22).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
2. Route flexible gas line, included, from fireplace
control to equipment shutoff valve through side
or rear access holes in outer casing.
3. Apply pipe joint sealant lightly to male
threads of gas connector attached to flexible
gas line/equipment shutoff valve (see Fig-
ure 23, page 18).
CAUTION: Avoid damage to
gas control. Hold gas control
with wrench when connecting it
to gas piping and/or fittings.

We recommend that you install a sediment trap in
supply line as shown in Figure 21. Locate sedi-
ment trap where it is within reach for cleaning.
Install in piping system between fuel supply and
heater. Locate sediment trap where trapped mat-
ter is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them from
going into fireplace controls. If sediment trap is
not installed or is installed wrong, fireplace may
not run properly.
