22 PC 45 Corn/Pellet StoveFEEDER DOES NOT FEED1. No fuel in hopper.2. Firebox draft may be too low for low draft pres-sure switch in feeder circuit to operate. Check forclosed doors, loose or missing gasket on doorsor hopper lid, faulty pressure switch.3. Feed motor will not run until ESP senses 200o F.Maybe you did not put enough pellets in the burnpot before lighting the fire.4. Something is restricting flow in the hopper orcausing the slide plate to stick.5. Feed motor has failed.PARTIALLY BURNED FUEL1. Feed rate too high.2. Draft too low.3. Burn pot may need to be cleaned.4. Combination of all the above.5. #6 status blink: A 6 blink control board statusindication is caused by poor or incomplete com-bustion. The circuit board has the ability to trackthe combustion through feed settings and ESP tem-peratures. When the control board has calculatedpoor or incomplete combustion it will shut downthe unit as a safety feature. (Poor or incompletecombustion is a contributer of creasote which maycause a chimney fire)A 6 blink status may be caused by several things:1. Blocked or partially blocked flue.2. Blocked or partially blocked inlet air.a. backdraft damper on the inlet pipe may bestuck closed.b. if outside air is installed the inlet cover may beblocked.3. The air chamber under the burnpot may be filledwith fines and small bits of ash.4. The holes in the burnpot may be getting filledwith ash or carbon buildup.5. Combus tion blower f an blades may needcleaned.6. There is no fuel in the hopper.COMBUSTION BLOWER RUNS AFTER SHUT DOWNThis is a normal function. The combustion blowerwill run for 5 hours after the stove is completelycool.SMOKE SMELLSeal the vent pipe joints and connection to stovewith silicone.FIRE HAS GONE OUT1. No fuel in hopper.2. Draft setting is too low.3. Something is restricting fuel flow.4. Feed motor or draft motor has failed.5. Power failure or blown fuse.SMOKE IS VISIBLE COMING OUT OF VENT1. Air-fuel ratio is too rich.A. Feed rate too high.B. Draft too low caused by a gasket leak.2. Unit is in an ignition cycle.LOW HEAT OUTPUT1. Feed rate too low2. Temperature setting too low (Stove Temp Mode)3. Draft too low because of gasket leak.4. Poor quality or high moisture fuel.PC 45 Trouble-ShootingCleaning Burn PotWhenever your stove is not burning, take theopportunity to scrape the burn pot to remove car-bon buildup. A vacuum cleaner is handy to removethe residue. Be sure the stove is cold if you use avacuum.Carbon buildup can be scraped loose with thefire burning using the special tool provided with yourstove. Scrape the sides of the burnpot (corn grate),and the floor and sides (pellet grate). The carbonwill be pushed out by the incoming fuel. Always weargloves to do this.Removing AshesTurn the Temp Dial to number 1 approximately30 minutes before removing ashes. This will resultin a cooler stove and ash pan.Maximum Feed Adjuster settings are notneeded in most cases. Operating in the normalrange (#2 corn) (#4 pellet) is recommended whenmaximum heat output is not required. The ESPprobe prevents the stove from being over-fired.Keep the stove free of dust and dirt.FuelThe PC 45 can burn corn with moisture levelsup to 16%, with 14.5% or less ideal.Pellet fuels are put into 3 categories in terms ofash content. Premium at 1% or less, Standard at3% or less and all others at 3% or more.The PC 45 is capable of burning all 3 catego-ries of pellets due to a patented feeder and burn potsystem.It should be noted, however, that higher ash con-tent will require more frequent ash removal and mayprovide less BTU's per pound. Normally, standardand high ash pellets cost less than premium pelletsand can be cost effective when burned in the PC 45.The moisture content of pellets must not exceed8%. Higher moisture will rob BTU's and may not burnproperly.Helpful Hints
