Installation Items Needed
• Phillips screwdriver
• sealant (resistant to propane/LP gas, not
provided)
1. Open lower louver (see Figure 17).
NOTICE: Most building codes
do not permit concealed gas
connections. A flexible gas line
is provided to allow accessibility
from the fireplace (see Figure 17).
The flexible gas supply line con
-
nection to the equipment shutoff
valve should be accessible.
2. Route flexible gas line, included, from
fireplace control to equipment shutoff
valve through side access holes in outer
casing.
3. Apply pipe joint sealant lightly to male
threads of gas connector attached to
flexible gas line/equipment shutoff valve
(see Figure 18, page 17).
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting it
to gas piping and/or fittings.

Sediment Trap
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 heater (see
Figure 16).
IMPORTANT:
Install equipment shutoff valve
in an accessible location. The equipment
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 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.
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 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.
