2. Second Stage - The next stage of burning, the secondary
stage, is the period when the wood gives off flammable
gases which burn above the fuel with bright flames.
During this stage of burning it is very important that the
flames be maintained and not allowed to go out. This will
ensure the cleanest possible fire. If the flames tend to
go out, it is set too low for your burning conditions. The
air control located at the upper right hand corner is used
to adjust for burn rates. This is called the Burn Rate Air
Control (Figure 10.1).
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 Burn Rate Air and 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
appliance 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 appliances in
the cleanest way possible. Doing this will allow us to
continue using our wood appliances for many years to
come.
D. Air Controls
Users will need to find their preferred setting between
high and low based on desired heat output, installation
configuration, and fuel type.
1. Burn Rate Air Control - This air supply enters at the
upper front of the firebox, near the top of the glass door.
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
Burn Rate Air Control. When the control is moved all the
way up it is on the High setting and when moved all the
way down it is on the Low setting (Figure 10.1).
2. Automatic Combustion Control System (ACC) - To
engage the Automatic Combustion Control (ACC) timer
system push the lever towards the back of the appliance
to the "HI" position, then pull forwards towards the front
of the appliance until the knob stops. The timer will
slowly close in about 25 minutes. Use this feature when
reloading fuel or if you want more air supplied to the fire
(Figure 10.2).

E. Using Burn Rate Air Control & ACC System
1. Start up and Reloading Fuel - Open both Burn Rate Air
Control and ACC systems fully. To do this with the Burn
Rate Air Controls push spring handle up to high. For the
ACC timer system push knob towards back of appliance
until the knob is located under the high position (Figure
10.1).
2. Maximize Heat with The ACC System - To maximize
heat output with the ACC timer System or also known
as high burn push the ACC Air Control lever towards the
back of the appliance and leave. This combined with
having the main burn rate control lever pushed up will
deliver the most amount of air needed to achieve the
highest amount of heat output (Figure 10.1).
3. Manual Timer Over-Ride - If you need to shut the ACC
system off before it goes through the cycle of shutting
itself off; 25 minutes, reach towards the back of the
appliance on the right side and pull the lever towards the
front of the appliance.
