Operation
LIGHTING INSTRUCTIONS
CAUTION:
DO NOT USE CHEMICALS OR FLUIDS TO START THE FIRE
HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
Before lighting your heater for the first time, make sure that all items are out of the hopper, ash pan and firebox
area. Press the “On” button and allow your heater to run for at least 4 minutes, to check for proper operation. Once your
heater is started, you will notice that the draft fan starts immediately. If you press the “Heat Setting” button up, you will
increase the heat setting as well as the draft fan speed. After 3 minutes, the auger and agitator will start rotating. Note:
The room fans will not operate until your furnace reaches preset operating temperatures. If proper operation of your
heater is confirmed, you can add fuel to the hopper and allow the auger to purge the fuel to the firepot.
DAILY OPERATION
 The hopper and furnace top will be hot during operation; therefore, you should always use some type of
hand protection when refueling your furnace.
 Never place your hand near the auger while the furnace is in operation.
In the event of a power outage, the furnace will not function. It is very important that unit be vented properly, as the
natural draft is needed to clear the smoke from the furnace during a power outage. In case of power outage, remove any
installed air filters from the duct system. This will help circulate air through your system and not overheat the appliance.
If the unit was “ON” when the power outage occurred, one of the following will take place when power is restored:
START-UP PROCEDURE
1.) If the furnace is still warm, it will resume feeding fuel and continue to operate normally. If the fire has gone out, you
will have to press the “OFF” button and then the “ON” button again to begin a new start-up sequence.
• Turn the Heater to the “OFF” position and place a small handful of wood pellets or fire starting pellets (Pellets that
already contain fire starter) in the firepot.
2.) If the furnace has cooled-off, it will reset to its “OFF” condition. At this point, you may press the “ON” button to
begin a new start-up sequence.
NOTE: Even if you are burning corn or other fuels in your unit, wood pellets make an excellent source of starter
fuel. Corn can be very difficult to properly ignite.
• Squirt only a small amount of fire starter gel on top of the wood pellets (NOT necessary if using fire starting pellets).
• Light the fire starter and wait approx. 1-minute for it to start actively burning.
• Press the “On” button, adjust the heat range to read “Cr-3” or “Pr-3” depending on fuel setting. Pull the damper out
approximately 1 inch. This will automatically match your feed rate with the proper combustion air. As you increase the
heat setting, your feed rate and combustion air increase together. Once the unit reaches operating temperature, you
may reduce the heat setting.
• Three minutes after turning the stove “On”, the auger will begin feeding fuel into the firepot along with the agitator
turning. You should have the starting fuel completely burning in the firepot as the agitator rotates. NOTE: If the starting
fuel is not burning hot enough, you may see the fire begin to go out as new fuel is being added. If this occurs, pressing
the “Auger Delay” button will allow the auger to pause for 1 minute. Pressing the “ON” button will resume the auger
if 1 min. is too long. If not enough fuel is the reason for not burning, pressing and holding the “ON” button will allow
the auger to run continuously until you release the button.
• Once the fuel starts burning aggressively, you can adjust the heat setting to your desired range. Make sure that you
pull the damper out approximately 1 inch. It may need to be pulled out more for higher heat settings. Try opening a
1/4 inch at a time.
NOTE: The unit will also shut down in the event of an draft fan failure; if this is the case, the unit will not re-start and you
must contact Customer Service at (800) 750-2723.
safety and Convenience features
Your King incorporates a safety pressure switch that helps ensure proper operating conditions before feeding fuel to
the burn pot. Because the furnace works using an induced draft pressure, the furnace will not continue to operate if the
viewing door is left open, if the draft fan fails or if the exhaust system is blocked.
The temperature limit control will prevent your furnace from operating at abnormally high temperatures. Should the
furnace temperature begin to approach the factory pre-set limit, the temperature limit control will automatically slow down
the auger feed rate until the temperature returns to a normal condition. Both room air fans will also operate at full speed
until the furnace returns to normal operating temperatures.
If your furnace continues to cut back because it is reaching the temperature limits, reduce the “heat setting” to the next
lower setting.
Maintenance
 Failure to clean and maintain this unit as indicated can result in poor performance and safety hazards.
• As you begin to have better understanding of how the heater operates and the amount of heat you require, you can
adjust the heat settings up or down to your satisfaction.
 Unplug your stove’s electrical cord prior to removing the back panel or opening the exhaust system for any
inspection, cleaning, or maintenance work.
• Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or
“freshen up” a fire in this heater. Keep all such liquids well away from the heater while it is in use.
 Never perform any inspections, cleaning, or maintenance on a hot furnace.
• Overfire Protection - If the heater is being overfired, (burned too hot), the heater will automatically shutdown to avoid
damage to components in the heater. Refer to “Lighting Instructions” for proper use.
SHUT-DOWN PROCEDURE
WARNING: Never shut down this unit by unplugging it from the power source.
Press the “OFF” button on the control panel to put the furnace in shut down mode. At this time, the red light above the
“OFF” button will illuminate. Once this is done, the auger will stop feeding fuel, but the room air fan(s) and draft fan will
continue to operate. When the internal temperature of the unit drops below the factory preset temperatures, the room
air fans and draft fan will cease to operate. The red light will then shut off and the unit will be completely shut down.
Never shut down this unit by unplugging it from the power source. Doing so can cause damage to the appliance or cause
a fire. The hotter the unit is during its operation, the longer it will take for the furnace to complete the shut down cycle.
If the furnace stays on for more than 2 hours after pressing the “OFF” button and you are 100% sure that the fire is
out, the furnace can be unplugged from the outlet. After approximately 10 seconds, the unit can be re-connected to the
power source and the control board will be reset.
14USSC
 Do not operate furnace with broken glass , leakage of flue gas may result.
 Establish a routine for the storage of fuel, care of the appliance, and firing techniques.
 Check daily for creosote buildup until experience shows how often cleaning is necessary.
Exhaust System
The by products of combustion contain small particles of fly ash. Fly ash will collect in the exhaust venting system
and restrict the flow of flue gases. Incomplete combustion during startup, shutdown, and/or incorrect operation of the
furnace can lead to soot formation which will collect in the exhaust system. Therefore, it is important that the exhaust
system be inspected and cleaned at least monthly during the burning season. Be aware that the hotter the fire, the
less creosote is deposited, and that weekly cleaning can be necessary in mild weather, even though monthly cleanings
can be enough in the coldest months.
Check the clean out tees periodically to determine the required cleaning schedule. 3 or 4-inch chimney brushes are
available for chimney cleaning. If the exhaust system or outside air pipes have screens on them, frequently clean the
screen. A plugged or partially plugged screen will reduce combustion air and cause a fire to die or burn poorly.

Open the Ash Cleanouts and scrap all ash into the ash pan. Open the damper and allow the ashes to fall into the ash pan. The
damper may need to be slid in and out several times to clear any ash build-up. This may need to be done daily depending on fuel
consumption. Be sure the ash cleanouts located on either side of the damper are completely closed before operating.

Periodically remove and clean the burnpot and the area inside the burnpot housing. In particular it is advisable to clean out the holes
in the burnpot to remove any build up that may prevent air from moving through the burn pot freely.
Placing the Burnpot and the Agitator in a bucket of water and allowing it to soak will help with the removal of clinker build-up.
13
Remove the two cleanout slides on each side of the burnpot at the rear of the burn chamber to clean out all ash.

After the last burn in the spring, remove any remaining fuel from the hopper and the auger feed system. Scoop out the fuel and then
run the auger until the hopper is empty and fuel stops flowing (this can be done by pressing the “ON” button with the viewing door
open). Vacuum out the hopper. Thoroughly clean the burnpot, and firebox. It may be desirable to spray the inside of the cleaned
hopper with an aerosol silicone spray if your furnace is in a high humidity area. The exhaust system should be thoroughly cleaned.

GLASS
Prior to starting the first fire of the heating season, check the outside area around the exhaust and air intake systems for obstructions.
Clean and remove any fly ash from the exhaust venting system. Clean any screens on the exhaust system and on the outside air
intake pipe. Turn all of the controls on and make sure that they are working properly. This is also a good time to give the entire
furnace a good cleaning throughout.

Ashes should be placed in a steel container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible
floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained in the closed container until all cinders have been thoroughly cooled.

• Use corn with less moisture or starch.
PROBLEMCAUSE: Unit is reaching the “Almost Over-temp” preset.
Unit cycles up and down when on the
“HIGH” heat setting.
• Adjust the heat range to lower setting.
• Fuel burns hot causing the furnace to cycle between high setting and
lower settings.
Flashing Indicators
Several situations or events are indicated in normal operation by blinking display indicators or segments in the display:
Flashing On Indicator : This means that the furnace is in the “Lighting” state waiting for either a 3 minute timeout to
begin burning or for the furnace to reach the pre-set temperature whichever comes first.
Flashing Off Indicator : This indicates that the furnace is in the “Shutdown” state waiting for the OFF button, or for a
15 minute period after the furnace was turned off, or for the furnace to cool down, or for the door to be closed.
Flashing dash “-“ in Heat Range Display : This indicates that the furnace is in the normal run mode and is ramping
from the current heat range setting to the target heat range setting. Once the ramp is complete, the “-“ will stop flashing.
For ramping from heat range 1 to 3, the default time is 90 seconds between internal settings.
Flashing Automatic Mode Indicator : This indicates that the furnace is in normal operation and is running in the automatic mode. However, either the Draft Fan or Auxiliary setting is manually configured.
Flashing Draft Fan Setting Indicator : This indicates that the furnace is in normal operation and that the vacuum sensor detects a loss of pressure either because the door is open or because there is a negative pressure in the room with
respect to the exhaust.
Flashing Heat Range Setting Indicator : This indicates that the furnace is in normal operation and that an overtemperature condition exists causing the fuel to stop.
Flashing Auger Delay Indicator : This indicates that th e furnace is in normal operation and that the hopper lid is open.
PROBLEMCAUSE: Corn is wet or it has a very high moisture content.
Corn builds up and is not burning completely. Steam is coming from the corn.
• Use corn with a moisture content of 11% or less for best results.
