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 liquid
petroleum (LP) gas.

1. To 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.

to fireplace (see Figure 23). Carefully lift up
branch support and remove from fireplace (see
Figure 23).
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 23).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting it
to gas piping and/or fittings.
4. Apply pipe joint sealant lightly to male threads of
gas connector attached to flexible gas line/equip-
ment shutoff valve (see Figure 24).
5. Check all gas connections for leaks. See
Checking Gas Connections, page 18.
6. Replace branch support back into fireplace.
Feed flexible gas line into fireplace base area
while replacing branch support. Make sure
the entire flexible gas line is in fireplace base
area. Reattach branch support to fireplace with
screws removed in step 2.
