Control Board
The control board has a six position integrated switch which controls
the fuel feed rate, combustion blower speed and room air blower speed
simultaneously. There is a separate blower speed control that overrides
the integrated switch which will allows you to reduce the speed of the
room air blower, thus reducing the noise level of the stove.
The control board regulates all functions of the stove. The following is a
list of the board's components:
• LCD Display Screen - See LCD Screen Displays on Pages 21, 22 and
23. The LCD display provides information on the status of the stove,
burn mode, failure mode, burn setting, time left in start-up cycle etc.
which should result in reduced diagnosis time.
• Room Air Blower Speed - Adjusts blower speed from low to high set-
tings. When adjusting to lower speed settings, the feed rate may adjust
accordingly to the blower speed, so the stove will not overheat.
• Ignition / Heat Control- Initiates ignition and controls the level of
heat output from the stove.
• Igniter Fuse - Six amp fuse to protect the igniter heating element.
• Control Board Fuse - Three amp fuse to protect the control board.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
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 initiate the startup a second time by turning the
Ignition/Heat Control dial to the "off" position and then back to your desired
heat setting. It is important to always empty (when cool) the burn pot of
pellets before starting the stove 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 war-
ranty. It also may create a fire hazard in your home.
IF ANY EXTERNAL PART OF THE UNIT BEGINS TO
GLOW, YOU ARE OVERFIRING. Immediately turn
the heat control dial to the "OFF" position.
Filling the Hopper
To fill the hopper when stove is off:
1. Lift the hopper lid to it's 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 LCD screen on the controller to verify that
the stove is still in normal heating mode.
3. If the message on the screen does not say "Heating" rather it alter-
nates between "Hopper Left Open" and "Cooling Down" simply reset
the stove by turning the Heat Control Dial to "Off" and then back to
your desired heat setting and the stove will run the igniter for 4-5
minutes to make sure there is a sustainable fire after refueling.
NOTE: This is an exclusive feature of the Bella™ to assure the highest
reliability, safety and convenience.
