OPERATION GUIDELINES

HOW YOUR FIREPLACE SHOULD BE USED

This fireplace is intended for supplemental heating only and is not intended for use as a primary heating system.

This fireplace is designed to sit directly on a combustible floor. The fireplace must be installed with clearances to com- bustible building materials as specified by this manual. Only parts manufactured by Martin Hearth and Heating and labeled for use with this fireplace should be used in the installation of the fireplace except for special roof flashings that may be fabricated locally. The use of improper parts in the installation can be hazardous and voids the warranty offered by Martin Hearth and Heating.

This fireplace is designed to burn solid wood fuel (wood), UL- classified processed solid fuel fire logs, or a certified decorative gas appliance may be installed in the fireplace as described later by this instruction manual.

This fireplace is not designed to burn coal, unplumbed liquid fuels, unplumbed gaseous fuels or household refuse. Any attempt to burn these fuels in the fireplace can be hazard- ous.

HOW YOUR FIREPLACE WORKS

As wood is burned in the fireplace, room air entering the fireplace is circulated around the fireplace firebox. This air circulation protects the firebox from overheating. Air circula- tion through the fireplace must not be blocked or restricted in any manner. Blocking or restricting air circulation through the fireplace can cause a fire hazard.

RESIDENTIAL INSTALLATION

In residential type installation, an AK4 outside combustion air kit may be connected to the left side of the fireplace to allow outside air to enter the firebox through a dampered opening in that side of the fireplace. This outside combustion air feature reduces the room air used for combustion and prevents exces- sive heat loss from the room. When the fireplace is in use, the fireplaceʼs “outside combustion air” damper connected to an AK4 may be opened to allow air from outside to enter the fireplace firebox. When the fireplace is not in use, the “outside combustion air” damper should be closed to prevent cold air from entering the firebox. An “outside combustion air” damper is open when its control lever is up and closed when its control lever is down. A control lever for the outside combustion airdamper is located inside the firebox near the top of the side firebrick on the left side of the fireplace. The design of the fireplace allows the routing of the combustion air duct downward or horizontally to obtain the outside combustion

air; this permits flexibility in planning your installation. See Figures 24 thru 27 and their instructions for typical installa- tion of outside combustion air kits. Review the precautions and recommendations in this manual pertaining to outside combustion air.

Note: Outside air for combustion is optional in residential type installations unless required by local codes. Outside air for combustion it is mandatory in manufactured home installations. Use an AK6 outside combustion air kit in manufactured home installations, instead of the AK4 offered for residential type installations.

GLASS DOORS

Glass doors (models GD36BA, GD36PBA, GD36SSA, GD42BA, GD42PBA and GD42SSA by Martin Hearth and Heating) may be installed to receive the maximum benefit from your fireplace. For large fires, the maximum heating benefit from the fireplace will be obtained with the doors open due to the high amount of radiant heat being emitted out of the front opening of the fireplace. With a small fire, or before retiring in the evenings, it is best to operate the fireplace with the doors closed to prevent excessive room air from being drawn up the chimney. When the doors are open, the mesh screens should be closed to help keep burning embers from popping out of the firebox.

Note: Glass doors are mandatory on fireplaces installed in manufactured homes.

WARNING	Fireplaces equipped with glass doors
	should be operated only with the
	opening, creating risks of both fire and
	glass doors fully open or fully closed.
	If doors are left partly open, gas and
	flame may be drawn out of the fireplace
	smoke.
