CWC Series Woodburning Fireplace
87D1504
Only unvented gas log sets which have been found to comply with
the Standard for Unvented Room Heaters, ANSI Z21.11.2, are to be
installed in this fireplace.
If installing an unvented gas log set, refer to statement below:
Installing Line for gas Logs
MHSC fireplaces are designed to accept a 1/2" gas
line for installation of an approved gas appliance.
(MHSC manufactures a wide variety of gas logs for
use in MHSC 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 access hole in the outer
casing of fireplace and remove insulation from gas line
tube. (Fig. 27)
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
screwdriver or small chisel and hammer, carefully tap
around the knockout until it loosens and falls out.
Install 1/2" 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 out-
side 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
appliance, the finishing materials 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.) incorporat-
ing an automatic shut-off 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 accor-
dance with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54 (latest edition).
