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 ).
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. Never use
sealant on flare threads.
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 .
Locate sediment trap where it is within reach
for cleaning. Install in piping system between
fuel supply and fireplace. 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 gas controls. If sediment trap
is not installed or is installed wrong, fireplace
may not run properly.
