For propane/LP connection only, the installer
must supply an external regulator. The exter-
nal regulator will reduce incoming gas pres-
sure. You must reduce incoming gas pressure
to between 11" and 14" of w.c. pressure. If
you do not reduce incoming gas pressure,
fireplace regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 20. Pointing the 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.
If pipe is too small, undue loss
of volume will occur.
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 21).
IMPORTANT:
Install main gas valve (equip-
ment shutoff valve) in an accessible location.
The main gas 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/drip leg in supply line as shown in Figure
21. Locate sediment trap/drip leg where it is
within reach for cleaning. Install in piping sys-
tem between fuel supply and fireplace. Locate
sediment trap/drip leg where trapped matter
is not likely to freeze. A sediment trap traps
moisture and contaminants. This keeps them
from going into fireplace gas controls. If sedi
-
ment trap/drip leg is not installed or is installed
wrong, fireplace may not run properly.
