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 oxygento mix with the unburned gases, helping to create thesecond, third and fourth combustion process.• This air is regulated by the Burn Rate Air Control.• There are four settings High, Medium-High, Medium-Lowand Low.• When the control is raised all the way up it is on the Highsetting and when pushed all the down it is on the Lowsetting. Figure 12.1.I. Burn Rates and Operating EfficiencyThis wood heater has a manufacturer-set minimum lowburn rate that must not be altered. It is against federal reg-ulations to alter this setting or otherwise operate this woodheater in a manner inconsistent with operating instructionsin this manual.For maximum operating effi ciency1. Burn dry, well-seasoned wood.2. Follow these burn rate instructions below and refer toFigure 12.1*NOTE: These are guidelines. Actual settings may vary withtype of wood, chimney draft, altitude and other variables.Burn Rates1. 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 AirControl back until it stops.• The blower tends to cool the appliance. Leave the bloweroff until the burn is well established, i.e., 30 minutes.• After loading the appliance with wood and starting thefire, set both controls to the desired setting by followingthe 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 stopsand leave it there.• This setting over-rides the timer system (ACC) so youmust 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 itstops (top marker) to a fully open position.• Push the Start-Up Air Control all the way back until itstops and then pull forward until it stops.• This activates the timer system (ACC).After activating the timer (ACC), if the control is placedwithin 3/8 inch (9.5mm) inward from the full OUT positionit will allow rear air to enter the firebox. This will not inter-fere with the timer gradually closing the front air channel in20-25 minutes. If control is set full inward on “HI” it over-rides the timer (ACC).*NOTE: These are approximate settings, and will vary withtype of wood or chimney draft. Due to altitude and otherenvironmental circumstances, this operational informationis a guideline only.4. Medium-Low Burn Rate - 10,000 to 15,000 BTU/hr*• Raise the Burn Rate Air Control up to the bottom of themiddle marker and stop.• Push the Start-Up Air Control all the way back until itstops 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.• Push the Start-Up Air Control all the way back until itstops and then pull forward until it stops.• This activates the timer system (ACC).WARNINGRisk of Fire or Chimney Fire.Avoid OverfireDO NOT over-ride the Automatic CombustionControl when the burn rate is set to HIGH
