Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not provided)
1. Route flexible gas line (provided by installer) from equipment
shutoff valve into fireplace through side or rear access holes in
outer casing (see Figure 20).
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 21). The flexible gas supply line connection 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.
2. Apply pipe joint sealant lightly to male threads of gas connec-
tor attached to flexible gas line (see Figure 21). Connect flex-
ible gas line to flexible gas line attached to gas valve of fire-
place (see Figure 21).
3. Check all gas connections for leaks. See Checking Gas Con-
nections, page 14.
4. Feed flexible gas line into fireplace base area. Make sure the
entire flexible gas line is in fireplace mantel base area.

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.
We recommend that you install a sediment trap in supply line as
shown in Figure 19, page 13 . Locate sediment trap where it is within
reach for cleaning. Install in piping system between fuel supply and
heater. 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.
