The Harman PC45 Corn And Pellet Stove

The Harman PC45 corn and pellet stove was designed primarily to burn corn. Some adjustment is needed to burn pellets. Burning corn, it produces 45,000 btu. With pellets, this rises to 50,000 btu.

The igniter in this stove has a 400 watt element which will light a fire in corn in under five minutes. Using pellets, ignition takes less than a minute.

The corn burnpot has a rotating agitator to stir the burning corn. A spare burnpot and agitator are supplied with this unit. At cleaning time, swap the used components for fresh ones and place the used ones in water to clean.

The Harman PC45 is a step top and pedestal design with the ability to add a hopper extension, increasing the capacity to 145 lbs. and the burn time to 160 hrs.

The room temperature probe speeds up or slows the stove down to compensate for temperature change and takes frequent readings of temperature trends. The exhaust heat sensor adjusts the stove according to the quality of fuel being burned.

For most heat settings other than maximum, the stove is capable of running without its distribution blower being turned on. This means that you can have a quiet time with a view of a good fire.

The control board has some diagnostics to help isolate any problems. There is also a port where a Harman dealer can plug in a diagnostic tool.

The burn pot in the Harman PC45 is very visible through the viewing window in this stove, and only partially hidden by the optional log set.

An optional burn pot is needed to burn pellets, changes will be needed to the control board and the combustion blower air intake should be changed for the larger one. All this comes as a kit with instructions.

The battery backup offered by Harman is not supported by onboard electronics. It's an inverter unit made by Surefire and will work effectively with any pellet stove. See the link above.


Remove ash every one or two days if burning corn on high, after a ton if burning pellets

Clean the stove after a month if burning corn, two or three months if burning pellets:
Clean and scrape the burn pot, clean the heat exchanger, clean ash from the inside of the stove, clean the combustion blower fan and internal flue. Remove fines from the fuel delivery system.

Once a year

Inspect and clean the flue if necessary.
