Installing Line for Gas Logs
Majestic Fireplaces are designed to accept a 1/2"
(13 mm) gas line for installation of an approved gas
appliance. (MHSC manufactures a wide variety of gas
logs for use in Majestic 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 fire-
place and remove insulation from gas line tube. (Fig. 29)
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" (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.
Note:
Local codes may require removal of flue damper
when installing any type of gas appliance in a fireplace.
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.
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
decorative gas appliance only when (1.) incorporating
an automatic shutoff device and (2.) complying with the
Standard for Decorative Gas Appliances for Installation
in Vented Fireplaces (ANSI Z21.60)
or
CSA draft re-
quirements for Gas-Fired Log Lighters for Woodburning
Fireplaces (Draft No. 4, August 1993).
Decorative gas appliance should be installed in accor-
dance with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54 (latest edition).
