Yosemite 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 coal bed.  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 evenly 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 
OUTSee Figure 19A.
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 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.
