INSTALLING DAMPER CLAMP
Secure the damper stop clamp provided to the leading
edge of the damper as shown in Figure 3. If for any rea-
son this clamp doesn't work on your fireplace, another
suitable clamp or permanent stop must be installed, or
the damper blade must be cut or removed.

CONNECTING TO GAS SUPPLY
WARNING: A qualified service
person must connect log set to gas
supply. Follow all local codes.
Installation Items Needed
Before installing log set, make sure you have the
items listed below.
• piping (check local codes)
• sealant (resistant to Propane/LP gas)
• equipment shutoff valve
• test gauge connection
• adjustable (crescent) wrench or pliers
• sediment trap
• tee joint
• pipe wrench
CAUTION: Use only new, black
iron or steel pipe. Internally-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 vol-
ume to log set. 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 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.
We recommend that you install a sediment trap in
supply line as shown in Figure 4. Locate sediment
trap where it is within reach for cleaning. Install in
piping system between fuel supply and appliance.
Locate sediment trap where trapped matter is not
likely to freeze. A sediment trap traps moisture and
contaminants. This keeps them from going into log
set controls. If sediment trap is not installed or is
installed wrong, log set may not run properly.
