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 24).
IMPORTANT:
Install an equipment shutoff valve
in an accessible location. The equipment shutoff
valve is for turning on and shutting off the gas to
the appliance.
Check your building codes for any special re-
quirements 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 liq-
uid petroleum (LP) gas.
We recommend that you install a sediment trap in
supply line as shown in Figure 24. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and fireplace.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into fire-
place controls. If sediment trap is not installed or is
installed wrong, fireplace may not run properly.

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 support
to fireplace (see Figure 25). Carefully lift up
branch support and remove from fireplace (see
Figure 25).
3. Route flexible gas line, included, from fire-
place control to equipment shutoff valve
through side or rear access holes in outer
casing.
NOTICE: Most building codes
do not permit concealed gas
connections. A flexible gas line
is provided to allow accessibility
from the fireplace (see Figure 25).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
