Burn Rates And Operating Effi Ciency - Quadra-Fire 57ST-ACC Owner's Manual

5700 STEP TOP ACC
2. Burn Rate Air Control
This 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 second, third and fourth combustions. 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 10.1.
F. Burn Rates and Operating Effi ciency
This wood heater has a manufacturer-set minimum low
burn rate that must not be altered. It is against federal reg-
ulations to alter this setting or otherwise operate this wood
heater in a manner inconsistent with operating instructions
in this manual.
For maximum operating effi ciency
1. This appliance has a timer system (ACC) that operates
the stove at its maximum effi ciency removing any guess
work for the homeowner. Follow the instructions below
for each burn rate for the Start-Up Air Control and Burn
Rate Air Control. Figure 10.1.
2. Burn dry, well-seasoned wood.
Burn Rates
1. Starting a Fire and Reloading
Open both controls fully by raising the Burn Rate Air
Control all the way up until it stops and slide the Start-up
Air Control back until it stops. After loading the stove with
wood and starting the fi re, set both controls to the desired
setting by following the burn rate instructions below.
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.
2. High Burn Rate - Maximum Heat - 30,000+ BTU/hr
Raise the Burn Rate Air Control all the way up until it stops
(top marker) to a fully open position. Slide the Start-Up Air
Control all the way back until it stops (HI marker) and leave
it there. This setting over-rides the timer system (ACC)
so you must monitor the fi re closely while in this setting.
WARNING
Risk of Fire.
When set on High Burn Rate and over-riding the Auto-
matic Combustion Control system an overfi re situation
can occur and could result in a chimney fi re.
Overfi ring will void the stove warranty.
3. Medium-High Burn Rate
Raise the Burn Rate Air Control all the way up until it
stops (top marker) to a fully open position. Slide the

-
15,000 to 30,000 BTU/hr
Start-Up Air Control all the way back until it stops (HI
marker) 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. Slide the Start-Up Air Control
all the way back until it stops (HI marker) and then pull
forward until it stops. This activates the timer system
(ACC).
5. Low Burn Rate - Below 10,000 BTU/hr
Leave the Burn Rate Air Control at the bottom marker.
Slide the Start-Up Air Control all the way back until it
stops (HI marker) and then pull forward until it stops. This
activates the timer system (ACC).

After activating the timer (ACC), if the control is placed
within the rear air section on the label it will allow rear air
to enter the fi rebox. This will not interfere with the timer
gradually closing the front air channel in 25 minutes. If
control is set on "HI" it over-rides the timer (ACC).
