Installing Line for Gas Logs

CFM Corporation fireplaces are designed to accept a 1/2 inch gas line for installation of an approved gas appli- ance. (CFM Corporation manufactures a wide variety of gas logs for use in CFM Corporation 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. 36)

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 knock- out 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

SHR Series Woodburning Fireplaces

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 appli- ance, 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 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 accor- dance with the National Fuel Gas Code, ANSI Z223.1/ NFPA 54 (latest edition).

CAUTION: WHEN USING DECORATIVE GAS APPLIANCE, FLUE DAMPER MUST BE SET IN FULLY OPEN POSITION. IF YOU HAVE GLASS DOORS ON THE FIREPLACE, THEY MUST ALSO BE FULLY OPENED.

WARNING: DO NOT OPERATE AN UNVENTED GAS LOG SET IN THIS FIRE- PLACE WITH THE CHIMNEY REMOVED.

WARNING: WHEN INSTALLING AN UNVENTED GAS LOG SET, THE CFM CORPORATION MODEL AH3244BK OR AH3244PB 4" ADJUSTABLE HOOD MUST BE USED.
