OPERATING INSTRUCTIONS
High Fuel/Ember Bed Control
If under the above display conditions, you have
accumulated a high fuel/ember bed, the following
guidelines should help you eliminate the problem
and stabilize the fuel bed for future use. These
should be one-time changes and settings for as
long as you continue to use the same fuel. i.e.
Corn or Wheat.
Burn-pot fuel bed
: If you cannot see 5” of the
burn-pot wall above your fuel/ember bed, the
level is too high (refer to Diagram 11b in "Low
Fuel/Ember Bed Control" section).
a.
Gradually increase combustion air to digital
reading “12” by pressing icon 2.
b.
Gradually increase ash removal to digital
reading “12” by pressing icon 4.
These will both show on display “A”.
At this point you will notice an increase in the
pressure reading on the round Pressure Gauge
(refer to Diagram 11a) indicator located below the
control panel. This will fl uctuate as you increase
or decrease air fl ow. (This is a good indicator to
help you manage your settings.
Clinker Prevention
Clinkers are a result of incomplete combustion
in your burn-pot and, if by chance they occur,
can be controlled with correct use of your
controls. Incomplete and poor combustion in
your appliance is related to the level of the fuel
bed height, the level of combustion air, the
temperatures in your burn-pot, and the rate
of ash extraction from your burn-pot.
In many cases, the use of certain gels and
starter materials can cause the formation
of clinkers in your burn-pot. Always use the
recommended fi re starter materials to start
your BioEnergy stove. In the event that
clinkers start to form during the initial 90
minutes, you can use the “poker” provided
to gently break this formation and allow the
unit to then continue as before. If you must
open the fi rebox door whilst the unit is in
operation, (to break a clinker), always open
gently and slowly.

Low Fuel/ember Bed Control
If under above display conditions, you have
accumulated a low fuel/ember bed the following
guidelines should help you eliminate the problem
and stabilize the fuel bed for future use.
Burn-pot fuel bed:
If you see more than 5 ½” - 6”
of the burn-pot wall above your fuel/ember bed,
the level is too low (refer to Diagram 11b).
After the initial start-up procedures and the unit
has run undisturbed or unaltered for at least
one hour, visually check the combustion air fl ow
and ash removal indicator levels on the control
panel. They should read “10” on the “A” display,
and “03” on the “B” display.
If under these display conditions, you have a
low
fuel/ember bed
, the following guidelines should
help you eliminate the problem and stabilize the
fuel bed for future use. These should be one-time
changes and settings for as long as you continue
to use the same fuel. i.e. Corn or Wheat.
a.
Gradually
decrease combustion air
to
digital reading “8” by pressing icon 1.
b.
Gradually
decrease ash removal
to digital
reading “8” by pressing icon 3.
These will both show on display “A”.
This will reduce the rate of ash removal, allowing
the fuel/ember bed to build to the appropriate
level. i.e. 5” from the top, or a 3” bed.
