PC 45 Trouble-Shooting

FEEDER DOES NOT FEED

1.No fuel in hopper.

2.Firebox draft may be too low for low draft pres- sure switch in feeder circuit to operate. Check for closed doors, loose or missing gasket on doors or 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 burn pot before lighting the fire.

4.Something is restricting flow in the hopper or causing the slide plate to stick.

5.Feed motor has failed.

PARTIALLY BURNED FUEL

1.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 status indication is caused by poor or incomplete com- bustion. The circuit board has the ability to track the combustion through feed settings and ESP tem- peratures. When the control board has calculated poor or incomplete combustion it will shut down the unit as a safety feature. (Poor or incomplete combustion is a contributer of creasote which may cause 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 be stuck closed.

b.if outside air is installed the inlet cover may be blocked.

3.The air chamber under the burnpot may be filled with fines and small bits of ash.

4.The holes in the burnpot may be getting filled with ash or carbon buildup.

5.Combustion blower fan blades may need cleaned.

6.There is no fuel in the hopper.

COMBUSTION BLOWER RUNS AFTER SHUT DOWN This is a normal function. The combustion blower will run for 5 hours after the stove is completely cool.

SMOKE SMELL

Seal the vent pipe joints and connection to stove with silicone.

FIRE HAS GONE OUT

1.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.

22 PC 45 Corn/Pellet Stove

SMOKE IS VISIBLE COMING OUT OF VENT

1.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 OUTPUT

1.Feed rate too low

2.Temperature setting too low (Stove Temp Mode)

3.Draft too low because of gasket leak.

4.Poor quality or high moisture fuel.

Helpful Hints

Cleaning Burn Pot

Whenever your stove is not burning, take the opportunity to scrape the burn pot to remove car- bon buildup. A vacuum cleaner is handy to remove the residue. Be sure the stove is cold if you use a vacuum.

Carbon buildup can be scraped loose with the fire burning using the special tool provided with your stove. Scrape the sides of the burnpot (corn grate), and the floor and sides (pellet grate). The carbon will be pushed out by the incoming fuel. Always wear gloves to do this.

Removing Ashes

Turn the Temp Dial to number 1 approximately 30 minutes before removing ashes. This will result in a cooler stove and ash pan.

Maximum Feed Adjuster settings are not needed in most cases. Operating in the normal range (#2 corn) (#4 pellet) is recommended when maximum heat output is not required. The ESP probe prevents the stove from being over-fired.

Keep the stove free of dust and dirt.

Fuel

The PC 45 can burn corn with moisture levels up to 16%, with 14.5% or less ideal.

Pellet fuels are put into 3 categories in terms of ash content. Premium at 1% or less, Standard at 3% 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 pot system.

It should be noted, however, that higher ash con- tent will require more frequent ash removal and may provide less BTU's per pound. Normally, standard and high ash pellets cost less than premium pellets and can be cost effective when burned in the PC 45.

The moisture content of pellets must not exceed

8%. Higher moisture will rob BTU's and may not burn properly.
