There are 2 impellers, one on each side of themotor. The convection blower pushes heated air through theheat exchange system into the room.3. Combustion BlowerThe combustion blower is located on the right side of applianceand is designed to pull the exhaust from the appliance andpush it out through the venting system.4. Feed SystemThe feed system is located on the right side of the applianceand can be removed as an entire assembly. The assemblyincludes the feed motor, mounting bracket, bearing and feedspring (auger). The hollow feed spring (auger) pulls pelletsup the feed tube from the hopper area and drops them downthe feed chute into the firepot.5. FirepotThe firepot is made of high quality ductile iron and has acleaning pull-out rod. The floor of the firepot opens forcleaning when you pull out the rod. Be sure that the floorreturns to a completely closed position or your appliance willnot operate properly.6. FuseThe fuse is located on the front of the junction box on the rightside of appliance. The fuse will blow should a short occurand shut off power to the appliance.7. Heat ExchangersThe heat exchangers transfer hot air from the exhaust systeminto convection air. Remove the stainless steel top baffle toaccess the heat exchangers. There are 2 clean out rodslocated under the heat exchangers.When describing the location of a component,it is always AS YOU FACE THE FRONT OFTHE APPLIANCE.A. Component Functions1. Control Boxa. The control box is located on upper right side ofappliance, behind the right side panel and above thevacuum switch.b. There is a light located inside of the control box. Theinternal light will turn green when the appliance hasreached a temperature of 175F (79C) in the firepot.and will turn red when it reaches 600 o F (315C).c. There is also an internal blue light located in the upperleft corner of the control box. When you plug in theappliance the blue light will automatically start blinking6 times in a row for 60 seconds and then will stop.NOTE:Do NOT open the control box. This will void thewarranty. If you need to plug in or remove the controlbox you must first unplug the appliance.8. Heat Output SwitchThe heat output switch is located on the upper right rearcorner. The function of the heat output switch is to regulatethe burn rates; low, medium and high settings.9. Hopper SwitchThe hopper switch is located in the upper right hand cornerof the hopper. This switch is designed to shut down the feedmotor whenever the hopper lid is opened.10. IgniterThe igniter is mounted on the base of the firepot. Combustionair travels over the red hot igniter creating super heated airthat ignites the pellets.11. Junction Box And Wiring HarnessThe junction box is located on the right side of the appliance,behind the right side panel. The junction box and wiringharness are replaced as one component.12. Power SupplyThe power outlet is located on the lower right side of theappliance on the front of the junction box. Check the wallreceptacle for 120 volt, 60 Hz (standard current). Make surethe outlet is grounded and has the correct polarity. A goodsurge protector is recommended. When operating with agenerator you need a least 600 watts of power, or with aninverter at least 800 watts of power available for the applianceduring the start cycle.13. Red Call LightThe red call light is on the front of the junction box, behindthe control box. The function of the red call light is to indicatethat the thermostat is calling for heat.14. Reset ButtonThe reset button is located on the back of the appliance onthe upper right corner of the side panel under the heat outputcontrol switch. The function of the button is to momentarilyopen the thermostat circuit, which restarts the system.15. ThermocoupleThe thermocouple is located on top of the firepot insidethe thermocouple cover (ceramic protection tube). Thethermocouple sends a millivolt signal to the control boxindicating the preset temperatures of the green and red lightshave been obtained.16. ThermostatThe appliance is designed to run on a 5 volt DC thermostat.The heat anticipator should be set on the lowest settingavailable.
