Burning FAQ
Burning FAQ's- How much combustion air do I need?Tuesday, 25 September 2007
Combustion air will need to be manually set with the type of fuel you are burning. LDJ suggests slowly opening from a closed position. You want to add air until the base of the flame lifts off of your fuel then back up a 1/8 to 1/4 inch.
Last Updated Thursday, 15 November 2007 - What is a clinker?Tuesday, 25 September 2007
A clinker is a blackish to grayish white hard clump. It is formed from the unburnt starches in the corn. Some corn produces more than others. Typically, if they are not large enough to impede the fire, they will eventually burn up or fall off into the ash bin.

- How often will I need to fill my bin?Tuesday, 25 September 2007
Usage will vary depending on several things: the type of fuel, building size, type of construction, insulation values, type of windows, tightness of the structure, geographic location, as well as the BTU loss versus the BTU input of the unit. You can expect to fill your hopper every 3-14 days.

- Why do I get popcorn ball-like formations?Tuesday, 25 September 2007
Typically, popcorn balls form from too much combustion air. The flame is burning too high off of the corn, which kind of melts the corn together to form shapes like popcorn balls. Your ash will also look more like hollowed out kernels of corn rather than a fine ash.

- What is the hard concrete-like substance in the bottom of my fire pot?Tuesday, 25 September 2007
This is the result of too many fines in your corn. It accumulates in the bottom of your fire pot and bakes into a hard material. It will prevent you from maintaining a constant fire. Reclean your corn and clean out the hopper, auger tubes and burn pot.
Last Updated Thursday, 15 November 2007 - How do I shut my unit down?Tuesday, 25 September 2007
Turn the toggle switch to the off position. On the furnace the room air blower will continue to run until the unit cools down below 100-110°F. It may take 3-5 hours for the fuel to completely diminish.
Last Updated Thursday, 15 November 2007 - Why do my augers run in the start position?Tuesday, 25 September 2007
There is a normally open low limit switch on the furnace heat exchanger and the boiler vent. When the temperature in the vent or heat exchanger reaches 110°F, the switch will close sending power to the augers.
Last Updated Thursday, 15 November 2007 - Why don't my augers run?Tuesday, 25 September 2007
The auger will not run until the low limit switch located on the furnace heat exchanger or the boiler vent has reached 110°F. When the switch reaches this temperature, the switch will close sending power to the augers. This may take up to 5-15 minutes of burning before the switch actually closes.
