3. Final Stage
The fi nal stage of burning is the charcoal stage. This occurs
when the fl ammable gases have been mostly burned and
only charcoal remains. This is a naturally clean portion of
the burn. The coals burn with hot blue fl ames.
•
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.
D. Combustible/Non-Combustible Materials
•
Combustible Material
Material made of or surfaced with wood, compressed
paper, plant fi bers, plastics, or any material capable
of igniting and burning, whether fl ame-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
o
C 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).
Start-Up Air System
The combustion air enters at the rear of the fi rebox 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
.
See Figure 25.1
.
Primary Air System
The primary air enters below the ash catcher and is directed
to the upper front of the fi rebox, near the top of the glass door
and to the lower front of fi rebox. This preheated air supplies
the necessary fresh oxygen to mix with the unburned gases,
helping to create second, third and fourth combustions. This
air is regulated by the Primary Air Control. For more primary
air push control
IN
, for less air pull control
OUT
.
