CONNECTING TO GAS
SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
WARNING: A qualified ser-
vice person must connect fire-
place to gas supply. Follow all
local codes.
WARNING: Never connect
fireplace to private (non-utility)
gas wells. This gas is commonly
known as wellhead gas.
IMPORTANT: Check gas line pressure
before connecting fireplace to gas line. Gas
line pressure must be no greater than 14
inches of water. If gas line pressure is higher,
fireplace regulator damage could occur.
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 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 20).
IMPORTANT: Install equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
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.
We recommend that you install a sediment
trap in supply line as shown in Figure 20.
Locate sediment trap where it is within
reach for cleaning. Install in piping system
between fuel supply and heater. 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.
