Installing Line for Gas Logs
CFM Corporation fireplaces are designed to accept a
1/2 inch gas line for installation of an approved gas ap-
pliance. (CFM Corporation manufactures a wide variety
of gas logs for use in Majestic Fireplaces units.)
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 fire-
place and remove insulation from gas line tube. (Fig.
32)
From inside the fireplace, locate the knockout on the
firebrick -- be sure you are on the appropriate or "gas
line" side of the fireplace. Using a flat bladed screw-
driver or small chisel and hammer, carefully tap around
the knockout until it loosens and falls out.
Install 1/2 inch 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 one (1) inch away from fireplace side.
NOTE: When installing an ANSI Z21.11.2 ventless ap-
pliance, the finishing material used for the mantel must
be rated at 250°F or greater.
