Automatic Combustion Control (Acc); Air Controls - Quadra-Fire 57ST-ACC Owner's Manual

5700 Step Top Wood Stove Series ACC
H. Automatic Combustion Control (ACC)
Typically, when you build a fi re, you open the air controls fully
and monitor the fi re to prevent it from going into an overfi re
situation and/or burning your wood up too quickly before you
shut down the air controls to the desired burn rate.
When using the Automatic Combustion Control (ACC) system,
you do not have to continually monitor the fi re. Once you
set the ACC system it will control the fi re for you. Follow the
instructions below to learn how to operate your stove with
ease.
I. Air Controls
1. Start-Up Air Control
The Start-Up Air Control has two primary functions.
The fi rst function is to activate the Automatic Combustion
Control system (ACC).
• Slide the Start-Up Air Control all the way back until it stops
at the "HI" indicator on the label and then pull forward to
the front of the appliance until it stops. Figure 10.1.
• The front air channel opens and allows air to enter the front
of the appliance for approximately 25 minutes.
• The front air channel gradually shuts down until it is com-
pletely closed at the end of the 25 minutes.
• The fi re is now controlled by the air supplied by the Burn
Rate Air Control. Figure 10.1.
• This function should be performed each time you reload
the appliance.
The second function of the Start-Up Air Control is operation
of the rear air system.
• Slide the Start-Up Air Control between the fi rst and third
marker as indicated on the label to allow rear air to enter
the fi rebox. Figure 10.1.
• The rear air is used primarily during a High Burn Rate.
• In some instances rear air is desired during normal opera-
tion to help with combustion of fuel towards the back of
the fi rebox particularly when burning hardwoods.
• The rear air is controlled independently from the ACC
system.
2. Manual Timer Over-Ride
If you need to shut the ACC system off before it shuts itself
off after 25 minutes (i.e. overfi re situation), reach down to
the bottom right rear corner and pull the lever toward you.
Figure 10.2.
3. Burn Rate Air Control
• The air supply enters at the upper front of the fi rebox,
near the top of the glass door.
• This preheated air supplies the necessary fresh oxygen
to mix with the unburned gases, helping to create sec-
ond, third and fourth combustions

High setting and when pushed all the down it is on the
Low setting. Figure 11.1 on page 11.
