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 log set. If
pipe is too small, undue loss of
volume will occur.
Installation must include an equipment shutoff
valve with "T" style handle, gas union and, for
propane/LP gas only, a plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from log
set (see Figure 4).
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.
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 a clogged burner injector.
WARNING: Use pipe joint
sealant that is resistant to liquid
petroleum (LP) gas.

Gas Hose (no longer
than 36" if required by
