* Purchase the optional CSA design-certi-
fied equipment shutoff valve from your
dealer. See Accessories, pages 24 and 25
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
We recommend that you install a sediment
trap in supply line as shown in Figure 16.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
INSTALLATION
Continued
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 16).
IMPORTANT: Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
Check your building codes for any special
requirements for locating equipment 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 17).
Carefully lift up log base assembly and
remove from fireplace (see Figure 17).
CONNECTING FIREPLACE

CAUTION: Do not pick up log
base assembly by burners. This
could damage burners. Only
handle base by grates.

3. Route gas line (provided by installer)
from equipment shutoff valve to fire-
place. Route flexible gas supply line
through one of the access holes.

4. Attach the flexible gas line to gas sup-
ply (see Figure 18). Check tightness of
flexible gas line attached to gas regu-
lator of fireplace (see Figure 18).
5. Check all gas connections for leaks. See
Checking Gas Connections, page 12.
6. Replace log base assembly back into
fireplace. Feed flexible gas line into fire-
place base area while replacing log base
assembly. Make sure the entire flexible
gas line is in fireplace base area. Reat-
tach log base assembly to fireplace with
screws removed in step 2.
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 18).
The flexible gas supply line con-
nection to the equipment shutoff
valve should be accessible.
