OPERATIONAL GUIDELINES

FLUE DAMPER

The fireplace also is equipped with a flue damper which must be open when the fireplace is in use. The flue damper control lever is located inside the fireplace. The counterweighted damper is operated by simply unlocking up to open or pulling and locking down to close the damper. When the fireplace is not in use, the damper should be closed to prevent cold air form entering the chimney as well as preventing warm air in the room from escaping up the chimney.

Note: It is normal for a small amount of smoke to be released from the upper portion of the fireplace the first few times you use your new Martin Hearth and Heating fireplace. This results from an oil residue on the metal. Open a door or window to allow the smoke to escape.

CHIMNEYS

All fireplace chimneys are in direct contact with cold air on the exterior of the structure. Consequently, when the fireplace is not in use, cold air can fall down the chimney of the fireplace to cool off the fireplace chase. Therefore, the fireplace chase must be insulated to minimize the risk of cold coming into the home. Even if the fireplace chase is adequately insulated, this cannot completely ensure that cold air coming into the structure will be eliminated. Cold air coming inside is a pos- sibility with any fireplace or device that freely uses air on the outside of the structure. Todayʼs homes are more energy-effi- cient and, therefore, better insulated and tightly constructed. Unfortunately, when air is removed from the house (by a bathroom fan or consumed by a furnace) additional air is needed to replace the air consumed. Unless the additional air is supplied, this can cause a negative pressure in the home. When this happens, the house will draw in outside air from the cracks in the windows, down the fireplace flue or other locations of air leakage in the home. Because cold air coming in may be unavoidable in some structures, Martin Hearth and Heating is not responsible for heat loss or air infiltration through or around the fireplace.
