Installing Line for Gas Logs
Vermont Castings Group fireplaces are designed to accept
a 1/2” (13 mm) gas line for installation of an approved gas
appliance. (Vermont Castings Group manufactures a wide
variety of gas logs for use in Vermont Castings Group
fireplaces.)
Be sure to have the appliance installed in accordance with
building codes.
Gas connection may enter from either left or right side of
the fireplace.
Locate appropriate gas line in the outer casing of fireplace
and remove insulation from gas line tube. (Fig. 24)
From inside the fireplace, locate the knockout on the fire-
brick -- be sure you are on the appropriate or “gas line” side
of the fireplace. Using a flat bladed screwdriver or small
chisel and hammer, carefully tap around the knockout until
it loosens and falls out.
Install 1/2” (13 mm) certified gas pipe through opening.
After gas pipe installation is complete, use insulation that
was removed from gas line tube to repack space around
the pipe. Material should be inserted from outside of the
fireplace and packed tightly to totally seal between the
pipe and tube.
NOTE: Gas pipe should not come in contact with any
wood structures until it has reached a point at least 1”
(25 mm) away from fireplace side.

Operation
Before the first fire, the location of the upper refractory
baffle (ceiling panel) should be checked. This part floats
intentionally and may move out of place during shipping
or installation of the fireplace. If the baffle is out of place,
the resulting improper air flow will cause dirty glass and
improper combustion. The baffle should be centered side-
to-side between the refractory sidewalls and be pulled for-
ward (toward the glass doors) until it rests on the front
sheet metal ledge.
Refer to the publication “How to Enjoy Your Woodburning
Fireplace” for starting and maintaining a wood fire.
Note that the BFC36 does not have a damper to open or
close. This is a tremendous efficiency increasing advan-
tage since there is no damper to potentially leave open
after a fire dies down. House air will not escape up the
chimney. Note also that the doors should remain closed at
all times except when starting or reloading a fire.
Burn only seasoned firewood. Typically, only two or three
burning logs are needed to provide efficient supplemental
heat and a bright decorative fire. In general, fresh wood
should not be loaded higher than about 2/3 the height of
the firebox.
BTU input of a gas appliance installed in fireplace should
be rated less than 100,000 BTU/Hr.
Gas pipe installation is intended for connection to a deco-
rative gas appliance only when (1.) incorporating an auto-
matic shutoff device and (2.) complying with the Standard
for Decorative Gas Appliances for Installation in Vented
Fireplaces (ANSI Z21.60)
or
CSA draft requirements for
Gas-Fired Log Lighters for Woodburning Fireplaces (Draft
No. 4, August 1993).
Decorative gas appliance should be installed in accordance
with the National Fuel Gas Code, ANSI Z223.1/NFPA 54
(latest edition).
CAUTION: When using decorative gas appli-
ance, flue damper must be set in fully open
position. Glass doors on the fireplace must
also be fully opened.
WARNING: Do not operate an unvented gas
log set in this fireplace with the chimney re-
moved.
WARNING: When installing an unvented gas
log set, the model CABL or CABR 4” adjust-
able hood must be used.
