. The metal chimney sections extending from the firebox top to beyond your roof are two walled and air-cooled. The inner passage, or flue, provides the exit for smoke and gases. 4. The flue damper is a two position (fully open or fully closed) mechanism operated by a handle found at the center top of the fireplace opening. It must be open when fire is present so smoke and gases can escape. It should be closed only when the fire is completely out – keeping room air from being lost up the flue. 5.

Disposal of Ashes Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are to be disposed of by burial in soil or other wise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled. d. Do not stack wood directly against the walls of your home. 8.

4. Build a pyramid of three split logs (split wood will light more quickly). Arrange the logs to provide plenty of air space between them. 5. Light the paper at both sides of the firebox. Note: When lighting a fire, some smoke may escape into the room, especially if the chimney is cold. To correct this, hold a lighted newspaper up inside the firebox, near the chimney opening. This will turn around any downdraft and clear the flue of cold air.

CAUTION If a smoking condition exists, glass doors should be closed during fireplace operation. ATTENTION Si vous apercevez de la fumee qui se degage du foyer, fermez les portes de verre. IMPORTANT See Page 7 for care and cleaning instructions for your glass doors. ATTENTION Voir la Page 7 pour les instructions de nettoyage des portes de verre. Combustion Air A proper amount of combustion air is important for your fireplace.

Before Each Use 1. Clean the firebox of excessive ashes. Some owners prefer to leave a small layer to insulate the cold refractory below the grate which helps fire starting. This fireplace has a factory supplied grate attached, it is permissible to remove the grate for cleaning; however, the grate must be re-attached to the fireplace before the next burn. 2. Keep the fireplace screens clean so combustion air flows freely. 3. Spot check the brick-like refractory for small cracks.
PAGE 8
Creosote Formation and Removal Refractories When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. All fireboxes contain a furnace refractory floor, back, and sides.

WARNING Continued overfiring can permanently damage your fireplace system. Some examples of overfiring are: • Burning quantities of scrap lumber, pine branches, paper or cardboard boxes which exceed the volume of the normal log fire. • Burning trash, chemicals or chemically treated combustibles. AVERTISSEMENT Si vous surchauffez continuellement votre foyer, vous pourriez l’endommager de façon permanente.
