3. Burn Rate Air Control
•
The 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 the
second, third and fourth combustion process.
• This air is regulated by the Burn Rate Air Control.
•
There are four settings High, Medium-High, Medium-Low
and Low.
•
When the control is raised all the way up it is on the High
setting and when pushed all the down it is on the Low
setting.
Figure 11.1.
I. Burn Rates and Operating Efficiency
For maximum operating efficiency
1. Burn dry, well-seasoned wood.
2. Follow these burn rate instructions below and refer to
Figure 11.1
*NOTE:
These are guidelines. Actual settings may vary with
type of wood, chimney draft, altitude and other variables.
Burn Rates
1. Starting a Fire and Reloading
•
Open both controls fully by raising the Burn Rate Air Con
-
trol all the way up until it stops and push the Start-up Air
Control back until it stops.
• The blower tends to cool the appliance. Leave the blower
off until the burn is well established, i.e., 30 minutes.
•
After loading the appliance with wood and starting the
fire, set both controls to the desired setting by following
the burn rate instructions below.
2. High Burn Rate - Maximum Heat*
• Raise the Burn Rate Air Control all the way up until it stops
(top marker) to a fully open position.
•
Push the Start-Up Air Control all the way back until it stops
and leave it there.
• This setting over-rides the timer system (ACC) so you
must monitor the fire closely while in this setting.
3. Medium-High Burn Rate
-
15,000 to 30,000 BTU/hr*
•
Raise the Burn Rate Air Control all the way up until it
stops (top marker) to a fully open position.
•
Push the Start-Up Air Control all the way back until it
stops and then pull forward until it stops.
• This activates the timer system (ACC).
4.
Medium-Low Burn Rate - 10,000 to 15,000 BTU/hr*
• Raise the Burn Rate Air Control up to the bottom of the
middle marker and stop.
•
Push the Start-Up Air Control all the way back until it
stops and then pull forward until it stops.
• This activates the timer system (ACC).
Figure 11.1 Activating Timer
After activating the timer (ACC), if the control is placed
within 3/8 inch (9.5mm) inward from the full OUT position
it will allow rear air to enter the firebox. This will not inter
-
fere with the timer gradually closing the front air channel in
20-25 minutes. If control is set full inward on “HI” it over-
rides the timer (ACC).
*NOTE:
These are approximate settings, and will vary with
type of wood or chimney draft. Due to altitude and other
environmental circumstances, this operational information
is a guideline only.
5. Low Burn Rate - Below 10,000 BTU/hr*
• Leave the Burn Rate Air Control at the bottom marker.
•
Push the Start-Up Air Control all the way back until it
stops and then pull forward until it stops.
• This activates the timer system (ACC).

WARNING
Risk of Fire or Chimney Fire.
Avoid Overfire
DO NOT over-ride the Automatic Combustion
Control when the burn rate is set to HIGH
