Cumberland Gap Wood Stove

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 stove 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 air controls for a short while before reloading.  
This livens up the coalbed.  Open door slowly so that ash 
or smoke does not exit stove through opening.  You should 
also 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.  To 
do this we need to learn to burn our stoves in the cleanest 
way possible.  Doing this will allow us to continue using our 
wood stoves for many years to come.
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.
