Startup/Normal Operation
When the circuit board is energized (the On/Off button is pushed), the start up cycle is initiated. This
starts a timed 8-15 minute cycle which allows the unit to light. If the unit is on AC power, the automatic
ignition system will energize. The igniter (optional feature) will glow red in the firepot for 10 minutes
and then shut off to protect the igniter. If the unit is on DC back up power the automatic ignition system
will not work and the unit will have to be lit manually. If the proof of fire thermodisk has not reached
operating temperature, the unit will go into the shut down mode. The circuit board is programmed to start
at a specified feed rate regardless of where the heat level setting is set. The unit should be set to the # 2 or
#3 heat level setting for the first 45 minutes. To restart the system if it does not light, push the ON/OFF
button and the startup sequence will start over again. If you open the door, it will stop the startup
sequence.
The circuit board is programmed to start on the # 2 heat setting regardless of what the advance heat
setting is on.
NOTE: Make sure that the wall thermostat is turned up so the unit will start. (When using T-STAT or
AUTO settings.)
Once the unit is operating at the proper temperature (usually after 10-15 minutes), the circuit board
switches from the start up cycle to normal operation. Then the manual draft slide can be set for the right
fuel load in the firepot.
The unit is not designed to be operated for long periods of time on the highest heat level setting.
Optimum efficiency is achieved by using lower settings (2 or 3). It is also recommended that the unit not
be run for extended periods of time on the #1 heat level setting. The draft blower and venting will fill up
with fly ash after a period of time. It is recommended to run the unit on a higher # heat level setting (2 or
3) once a week. Run it this way for a few hours to clear the venting and draft blower.
With all models, the manual draft will have to be adjusted when the higher (4-5) heat level settings are
used. The circuit board will automatically change the draft and also the room air speed when you change
heat level settings.
If you open the door, ash pan door, hopper lid, have negative or positive pressure in the home or place the
unit in a drafty location the vacuum pressure switch will shut off the auger and the unit will go into shut
down mode. If the unit does not respond, then the pressure switch will have to be re-set by pressing and
holding the start button for several seconds, or unplugging the power and starting over again.
Shutdown
To shut the unit down, simply press the On/Off button. The room fan and exhaust blower will continue to
operate until the low limit/cool down sensor tells it that the fire is out. At that point the exhaust fan will
continue to run for an additional 45 minutes to make sure there is no exhaust in stove.
CIRCUIT BOARD/CONTROL BOARD FUNCTIONS (How does the circuit
board operate?)
Before starting the MagnuM Biomass unit again, it is important to remember to clean out the firepot,
empty the ashes, clean out the heat exchangers, vacuum out the hopper if needed and fill the hopper
with fuel.
