Cumberland Gap Wood Stove

The Primary Air Slide Control located under the ashlip ad- justs the burn rates. Figure 27.1.

3. Final Stage

The final stage of burning is the charcoal stage. This occurs when the flammable gases have been mostly burned and only charcoal remains. This is a naturally clean portion of the burn. The coals burn with hot blue flames.

•It is very important to reload your appliance while enough lively hot coals remain in order to provide the amount of heat needed to dry and rekindle the next load of wood.

•It is best to open the Primary Air Control and the Start-Up Air Controls before reloading. This livens up the coal- bed and reduces excessive emissions (opacity/smoke).

•Open door slowly so that ash or smoke does not exit ap- pliance through opening.

•Break up any large chunks and distribute the coals so that the new wood is laid on hot coals.

Air quality is important to all of us, and if we choose to use wood to heat our homes we should do so responsibly.

We need to learn to burn in the cleanest way possible al- lowing us to continue using our wood appliances for many years to come.

E. Air Controls

Start-Up Air System

The combustion air enters at the rear of the firebox through the rear air tubes. This air supply is controlled by the Start- up Air Control. For more air push control IN, for less air pull control OUT.

Primary Air System

The primary air enters below the ash catcher and is directed to the upper front of the firebox, near the top of the glass door and to the lower front of firebox. This preheated air sup- plies the necessary fresh oxygen to mix with the unburned gases, helping to create secondary, tertiary and quaternary combustions. This air is regulated by the Primary Air Slide Control. For more primary air slide control LEFT, for less air slide control RIGHT.

D. Combustible/Non-Combustible Materials

•Combustible Material

Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or any material capable of igniting and burning, whether flame-proofed or not, plastered or unplastered.

•Non-Combustible Material

Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, slate, glass or plasters, or any combination thereof.

Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnance at 750 oC and UL763 shall be considered non-combustible materials.

•Non-Combustible Sealant Material

Sealants which will not ignite and burn: Rutland, Inc. Fireplace Mortar #63, Rutland 76R, Nuflex 304, GE RTV106 or GE RTB116 (or equivalent).
