CHECK GAS TYPE
Use only natural gas. If your gas supply is not natural gas, you must
install ON/OFF Safety Valve/Pilot Kit (see Accessories, page 17). Call
dealer where you bought log set.
If the fireplace does not have a gas supply shutoff valve, one must
be installed.
VENTING SPECIFICATIONS FOR INSTALLATION
The fireplace chimney flue and vent must be drafting properly. To
check the vent for proper drafting: Light a tightly rolled newspaper on
one end and place it at the inside front edge of the fireplace. Observe
the smoke and be sure the vent is properly drawing it up the chimney.
If the smoke spills out into the room, extinguish the flame and remove
any obstruction until proper venting is achieved.
The chimney flue must remain open a minimum of 3" at all times
during the operation of this log set.
For Massachusetts Residents Only
Installation of this vented gas log set in the Commonwealth of Mas-
sachusetts requires the damper be permanently removed or welded
in the fully open position.
INSTALLING DAMPER CLAMP
Secure the damper stop clamp provided to the leading edge of the
damper as shown in Figure 3. If for any reason 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" diam-
eter or greater to allow proper gas volume to log set.
If pipe is too small, undue loss of volume 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 log set (see Figure 4, page 8).
IMPORTANT:
Install equipment shutoff valve in an accessible loca-
tion. 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, page 7. Locate sediment trap where it is within
reach for cleaning. Install in piping system between fuel supply and
heater. 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.
