During this stage ofburning it is very important that the flames be maintainedand not allowed to go out. This will ensure the cleanestpossible fire. If the flames tend to go out, it is set too low foryour burning conditions. The air control located at the upperright hand corner is used to adjust for burn rates. This iscalled the Burn Rate Air Control (Figure 11.1).3. Final StageThe final stage of burning is the charcoal stage. This occurswhen the flammable gases have been mostly burned andonly charcoal remains. This is a naturally clean portion ofthe burn. The coals burn with hot blue flames.It is very important to reload your appliance while enoughlively hot coals remain in order to provide the amount ofheat needed to dry and rekindle the next load of wood. Itis best to open the Burn Rate Air and Start-Up Air Controlsbefore reloading. This livens up the coal bed and reducesexcessive emissions (opacity/smoke). Open door slowly sothat ash or smoke does not exit appliance through opening.You should also break up any large chunks and distributethe coals so that the new wood is laid on hot coals.Air quality is important to all of us, and if we choose touse wood to heat our homes we should do so responsibly.To do this we need to learn to burn our appliances in thecleanest way possible. Doing this will allow us to continueusing our wood appliances for many years to come.Figure 11.3Over rides timer & opensrear air to open lockedpositionOpen rear air medium airflowEngages timer push knobtowards HI then back toany point within dotted lineOpen rear air medium-lowair flowCloses front and rear airFigure 11.1Figure 11.2HIGHMEDLOWBurn RateAir ControlStart-UpAir ControlManualTimer (ACC)Shut DownPull Forwardto Shut DownInjury Risk.• Gloves recommendedCAUTIOND. Air ControlsUsers will need to find their preferred setting betweenhigh and low based on desired heat output, installationconfiguration, and fuel type.1. Burn Rate Air ControlThis air supply enters at the upper front of the firebox, nearthe top of the glass door. This preheated air supplies thenecessary 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. Whenthe control is moved all the way up it is on the High settingand when moved all the way down it is on the Low setting(Figure 11.1).2. Automatic Combustion Control System (ACC)To engage the Automatic Combustion Control (ACC) timersystem push the lever towards the back of the appliance tothe “HI” position, then pull forwards towards the front of theappliance until the knob stops. The timer will slowly close inabout 25 minutes. Use this feature when reloading fuel or ifyou want more air supplied to the fire (Figure 11.3).E. Using Burn Rate Air Control & ACC System1. Start up and Reloading FuelOpen both Burn Rate Air Control and ACC systems fully. Todo this with the Burn Rate Air Controls push spring handleup to high. For the ACC timer system push knob towardsback of appliance until the knob is located under the highposition (Figure 11.1).2. Maximize Heat with The ACC SystemTo maximize heat output with the ACC timer System or alsoknown as high burn push the ACC Air Control lever towardsthe back of the appliance and leave. This combined withhaving the main burn rate control lever pushed up willdeliver the most amount of air needed to achieve thehighest amount of heat output (Figure 11.1).3. Manual Timer Over-RideIf you need to shut the ACC system off before it goesthrough the cycle of shutting itself off; 25 minutes, reachtowards the back of the appliance on the right side and pullthe lever towards the front of the appliance (Figure 11.2).
