Harman PF100 Pellet Furnace

The PF100 burns pellet fuel and operates automatically to give you warm comfortable temperatures much like your existing forced air furnace. Simply fill the hopper with pellets and set the wall mounted temperature control to the desired setting and the PF100 will do the rest. If heat is required the fire will automatically light and burn at the proper rate to produce just the right amount of heat. If heating demand is reduced, the Harman PF100 will reduce the fire. If no heat is required the fire will go out, lighting again automatically if more heat is needed.
When the fuel in the hopper gets low a red light on the wall control will blink, telling you to add fuel to the hopper. The PF 100's huge ash pan allows three to four tons of pellets to be burned before the ash pan needs to be emptied. With the patented Harman feeder and burn pot even high ash pellets can be burned efficiently. The PF 100 can be installed as a stand alone hot air heating system or incorporated into existing hot air systems. A chimney is not required for venting. This direct vent system can also use outside air. Dual heat exchangers are used to extract maximum heat from the fuel which will help save you money.
