OPERATION
Control Board
The control board regulates all functions of the stove. The following is a
list of the board’s components:
Feeding light - lights up when the auger is feeding pellets into the
Burn-Pot.
Ready Light - lights up when stove is ready to operate.
Igniting Light - lights up when the stove is in the ignition sequence.
Start Button - is pushed to start the ignition sequence after the heat
selector knob is turned from off.
Heat Selector Knob - is turned to off to shut the stove off or turned
to a setting from 1 to high to regulate the burn rate.
Igniter Fuse - six amp fuse to protect igniter heating element.
Control Fuse - three amp fuse to protect the control board.
Lighting
1. Turn the heat selector knob (see Figure 42) to the heat level desired
- 1 through high - and the ready light will turn green.
2. Push the start button and the ignite and feeding lights will come on
and the lighting sequence will begin. For about the next 15 minutes
the stove will feed pellets cyclically into the Burn-Pot, the combustion
blower will come on and the igniter will heat up. During this sequence,
some smoke in the firebox is to be expected. After the igniting sequence
is complete, the stove will begin burning at the level indicated by the
heat selector knob.
Note: Upon the stove’s initial light up, or if the stove has previously run
out of pellets, the auger feed tube may not contain a sufficient number of
pellets to allow the stove to continue burning after the ignition sequence.
It may be necessary to push the start button a second time to run the
start sequence again. It is important to always empty (when cool) the
Burn-Pot of pellets before pushing the start button a second time.
Filling the Hopper
The hopper can be accessed by lifting the lid at the rear of the top of the
stove. The hopper will hold 60 pounds of pellets. Remove any contents
from the hopper and fill with pellets as follows:
To fill the hopper when stove is off:
1. Lift the hopper lid to its full opened position.
2. Fill the hopper with pellets.
3. Check to make sure there are no remaining pellets on top of the
hopper that may prevent the hopper lid from fully closing.
4. Close Hopper lid.
To fill the hopper when stove is in operation:
1. Repeat steps 1 thru 4 above.
2. When finished, check the burn pot to assure there is substantial
combustion taking place to light the pellets once the pellets start
feeding after refueling.
3. If combustion is not present in the burn pot then the unit will need
to be restarted. This can be done by turning the heat setting dial to
off and back to the desired heat setting 1 thru 5. You will then have
to press the start button to initiate ignition.
Caution: Failure to confirm pellets in the Burn Pot remain
burning after re-fueling may result in smoke escaping from the
unit. Smoke escaping the unit can also be a result of ignition
of the unit with excessive pellets located inside the burn pot.

Manual Operation
After the stove is burning (see lighting above), the heat selector knob
controls the pellet burn rate and the stove’s heat output. Turning the
knob to setting 1 allows the stove to burn about 1.8 pounds of pellets
per hour - about 8,500 BTUs per hour. Turning the knob to high allows
the stove to burn 4.7 pounds of pellets per hour - about 39,000 BTUs per
hour. Once set, the stove will continue to burn at this rate until shut off.
Thermostat Operation
This stove will operate with a low voltage thermostat. See Page 12 for
instructions on installing the thermostat. Once installed, the thermostat
will control the operation of the stove. Important: When connected to a
thermostat, it is necessary to push the ignite button for the initial burn,
when the electrical flow to the stove is interrupted, if the selector knob
is turned to off (and then back on), or if the stove runs out of pellets and
therefore shuts off. After the initial ignition sequence, when the thermostat
calls for heat (the room temperature is less than the temperature set on
the thermostat) and the heat selector knob is not in the off position, the
stove will burn at the heat selector knob setting. The higher the setting,
the quicker the room will heat up. Once the thermostat no longer calls for
heat (the room is up to the desired temperature), the stove will continue
to burn for one additional hour at the lowest setting. If the thermostat
does not call for heat again during that hour, the stove will shut off. Dur-
ing that hour, if the thermostat calls for heat again, the stove will again
burn at the heat selector knob setting until the thermostat no longer
calls for heat. If the stove shuts off after that hour it will relight when the
thermostat calls for heat.
WARNINGS
• Never empty pellets from the Burn-Pot into the hopper.
Pellets that may appear to be cool may retain enough
heat to ignite other pellets resulting in smoke or fire
damage.
• DO NOT OVERFIRE THIS STOVE. This may cause
serious damage to your stove and void your warranty.
It also may create a fire hazard in your home. IF ANY
EXTERNAL PART OF THE UNIT BEGINS TO GLOW, YOU
ARE OVERFIRING. Immediately slide the knob to the
"OFF" position on the control board.
