OPERATION

Control Board

The control board regulates all functions of the insert. 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 insert is ready to operate.
Igniting Light - lights up when the insert 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 insert 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.

Filling the Hopper

The hopper can be accessed by lifting the lid at the rear of the top of the
insert. The hopper will hold 60 pounds of pellets. Remove any contents
from the hopper and fill with pellets.

Lighting

1. Turn the heat selector knob (see Figure 34) 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
insert will feed pellets cyclically into the burn pot, the combustion fan
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 insert will begin burning at the level indicated by the
heat selector knob.
Note: Upon the insert's initial light up, or if the insert has previously run
out of pellets, the auger feed tube may not contain a sufficient number of
pellets to allow the insert 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.
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.

Manual Operation

After the insert is burning (see Lighting on this page), the heat selector
knob controls the pellet burn rate and the insert's heat output. Turning the
knob to setting 1 allows the insert to burn about 1.8 pounds of pellets per
hour - about 8,500 BTUs per hour. Turning the knob to high allows the
insert to burn 4.7 pounds of pellets per hour - about 39,000 BTUs per hour.
Once set, the insert will continue to burn at this rate until shut off.

Thermostat Operation

This insert 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 insert. Important: When connected to a
thermostat, it is necessary to push the ignite button for the initial burn,
when the electrical flow to the insert is interrupted, if the selector knob
is turned to off (and then back on), or if the insert 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
insert 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 insert 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 insert will shut off. Dur-
ing that hour, if the thermostat calls for heat again, the insert will again
burn at the heat selector knob setting until the thermostat no longer
calls for heat. If the insert shuts off after that hour it will relight when
the thermostat calls for heat.
