For propane/LP units, installer must supply
an external regulator. External regulator will
reduce incoming gas pressure. You must
reduce incoming gas pressure to between
11" and 14" of water. If you do not reduce
incoming gas pressure, heater regulator dam-
age could occur. Install external regulator with
the vent pointing down as shown in Figure 13.
Pointing vent down protects it from freezing
rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of
1/2" diameter or greater to allow
proper gas volume to fireplace
insert. If pipe is too small, undue
loss of volume will occur.
Installation must include an equipment shutoff
valve and plugged 1/8" NPT tap. Locate NPT
tap within reach for test gauge hook up. NPT
tap must be upstream from fireplace insert
(see Figure 14).
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.

We recommend that you install a sediment
trap in supply line as shown in Figure 14.
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 con-
taminants. This keeps them from going into
fireplace insert gas controls. If sediment trap
is not installed or is installed wrong, fireplace
may not run properly.
