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 fireplace controls. If sediment trap is not installed
or is installed wrong, fireplace may not run properly.
* Purchase the optional CSA design-certified equipment shutoff
valve from your dealer. See Accessories, page 29.

Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Remove fireplace screen. Remove two screws that hold fire-
place 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 fireplace control to
equipment shutoff valve through side or rear access holes
in outer casing.
NOTICE: Most building codes do not permit con-
cealed gas connections. A flexible gas line is pro-
vided to allow accessibility from the fireplace (see
Figure 25). The flexible gas supply line connection to
the equipment shutoff valve should be accessible.

4. Apply pipe joint sealant lightly to male threads of gas connec-
tor attached to flexible gas line/equipment shutoff valve (see

5. Check all gas connections for leaks. See Checking Gas Con-
nections, page 16.
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. 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.
