Automatic Combustion Control (Acc); Air Controls - Quadra-Fire EXPLR-III-PBK Owner's Manual

is used to adjust for burn rates. This is called the Burn Rate
Air Control. Figure 9.1
3. Final Stage
he final stage of burning is the charcoal stage. This occurs
T
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. Automatic Combustion Control (ACC)
Typically, when you build a fire, you open the air controls fully
and monitor the fire to prevent it from going into an over fire
situation and/or burning your wood up too quickly before you
shut down the air controls to the desired burn rate. With the
Automatic Combustion Control (ACC) system, you do not have
to continually monitor the fire. Once you set the ACC system
it will control the fire for you. Follow the instructions below to
learn how to operate your appliance with ease.
E. Air Controls
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 to the left it is on the High setting and
when moved all the way to the right it is on the Low setting.
Figure 9.1
2. Start-Up Air Control
The Start-Up Air Control function is to activate the Automatic
Combustion Control system (ACC). This function is performed
by pushing the control all the way back until it stops and then
pulling forward to the front of the appliance until it stops. This
activates the ACC system and opens the front air channel and
allows air to enter the front of the appliance for approximately
25 minutes. The front air channel gradually shuts down until it
is completely closed at the end of the 25 minutes. The fire is
now controlled by the air supplied by the Burn Rate Air Con-
trol. This function should be performed each time you reload
the appliance. Start up air can be locked open for High burn
setting if desired (see page 10 for instructions) Figure 9.1
3. Manual Timer Over-Ride
If you need to shut the ACC system off before it shuts itself
off after 25 minutes (i.e. over fire situation), reach down to
the bottom right and pull the lever toward you. Figure 9.2

Fire Risk.
• Always operate this appliance with the door closed
and latched except during start-up and re-fueling or
when using the fire screen.
• Operating with the door partly open can cause:
• Hot embers or sparks to fall out
• Flames and smoke may be drawn out from
firebox opening
Injury Risk.
• Gloves recommended
