CONNECTING TO GAS
SUPPLY
person must connect fireplace to
gas supply. Follow all local codes.
CAUTION: Never connect fire-
place directly to the propane/LP
supply. This fireplace requires
an external regulator (not sup-
plied). Install the external regula-
tor between the fireplace and pro-
pane/LP supply.
The installer must supply an external regu-
Top Brass Trim
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, fireplace regulator damage

could occur. Install external regulator with

the vent pointing down as shown in Figure

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"
or greater diameter to allow
proper gas volume to fireplace. If
pipe is too small, undue loss of
pressure will occur.
Installation must include a manual 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 17).
Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged fireplace valves.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.
Install sediment trap in supply line as shown
in Figure 17. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment 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.
