Control Board Operation

START BUTTON
The "START" Button turns on the pellet stove.
If the exhaust does not reach operating tempera-

ture within 30 minutes, the stove will automati-

cally shut down. The pellet stove can be restarted

by pushing the "START" Button again.

RESTART

AUGER ON (green LED) - The auger restarts and

returns to delivering fuel to the UltraGrate™.

STOP BUTTON
Note: The "START" Button has to be activated to

give power to the AUGER ON/OFF button.
The "STOP" button turns the pellet stove OFF.

When the LED is green, the auger is ON.
SHUT DOWN (LED off) - Auger turns OFF and

fuel delivery stops. The blowers will continue to

operate until the stove has cooled sufficiently.

Stove enters shut down mode.

HEAT OUTPUT BUTTON
When not using a wall thermostat, the "HEAT

OUTPUT" button provides the ability to burn

at five separate settings from low (#1) to high

(#5). The "HEAT OUTPUT" button regulates the

fuel feed setting and the combustion air supply

simultaneously.
Each time the "HEAT OUTPUT" button is pressed

the heat output will advance to a higher setting.

When at the highest setting (#5), if the button

is pressed again it will go back to the lowest

setting. Settings can be changed at any time

but will only take affect after the start-up cycle

is complete.

CONVECTION (ROOM AIR) BLOWER

BUTTON
The "BLOWER" button operates the convection

blower. This will change the flow of hot air into

the room. Five settings are available from low

(#1) to high (#5). When the "BLOWER" button

is pressed, the green indicator light will scroll

from low to high. When at the highest setting

(#5), if the button is pressed again it will go

back to the lowest setting.
When the "HEAT OUTPUT" button is on position

#5, the lowest blower setting is #3. When the

heat output button is on position #4, the lowest

blower setting #. This is a safety precaution

to protect against overheating. Blower settings

can be changed at any time, but will only take

affect after the start-up cycle is complete.

Note: The control board has an internal memory

which recalls the last setting prior to loss of

power.

IMPORTANT NOTE: If the fuel feed trim or combustion air trim needs to be adjusted, contact

your dealer or qualified technician to calibrate internal software. The trim controls should

only be adjusted for the proper flame if all other options did not achieve proper adjustment.

It is recommended that the damper be used to fine-tune your stove to your particular fuel and

installation configuration (see Damper Adjustment on Page 9 and Damper Adjustment Guide-

lines on Page 20).

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 press the “STOP” button on the

control board.

Fuel Delivery Rate

The "HEAT OUTPUT" button manages the fuel delivery rate by controlling the amount of time the

auger motor will run as follows:

* Feed rates are approximations only. Actual feed rate will vary depending on size, quality and length

of fuel used and variations in line voltage.

Estimated heat input based on fuel value of 8400 BTU per lb. of fuel.
