Biopel MINI - Installation and Operation Instructions
49
i.
Max feed work - set shorter feeder operating time
ii.
Min feed pause - set a longer feeding pause time
c.
Reduce air quantity: Service menu, Feeder settings, Work
i.
Max fan power - set a lower number
d.
Increase air quantity: Service menu, Feeder settings, Work
i.
Max fan power - set a higher number
By
making these changes you can adjust the flame size and therefore the combustion quality.
After the ignition phase, wait 10 minutes for the burner to reach maximum power and then make
the changes.
2.
Incorrect flame at min. power:
a.
Reduce the boiler power to the minimum:
Wait until the CH temperature is close to the set value, or set the same values in the Service
menu, Feeder Settings, Work, for min. and max. power. Example:
i.
Service Menu: Feeder settings, Work, for min. and max. power:
I.
Max. feeding work = 2s (value for max. power)
II.
Min. feeding work = 2s (value for min. power)
III.
Max. feeding pause = 10s (value for min. power)
IV.
Min. feeding pause = 10s (value for max. power)
Now the same values are set for running the feeder at min. and max. power. Wait 10mins for the
flame to stabilise and make any corrections, see below
.
b.
Flame extension: Service menu, Feeder settings, Work
i.
Min. feed work - set higher feeder operating number
ii.
Max. feeding pause - set a shorter feeding pause time
c.
Flame Shortening: Service menu, Feeder settings, Work
i.
Min. feed work - set lower feeder operating number
ii.
Max. feeding pause - set a longer feeding pause time
d.
Reduce air quantity: Service menu, Feeder settings, Work
i.
Min. fan speed operation - set a lower number
e.
Increase air quantity: Service menu, Feeder settings, Work
i.
Min. fan speed operation - set a higher number
It is important that the flame is stable during minimum power and there is no risk of extinction
during boiler operation.
3.
Unburnt pellets in the ashtray:
a.
Reduce fan speed: Service menu, Feeder settings, Work
i.
Max. fan power - set a lower number
b.
Reduce feeder operating time: Service menu, Feeder settings, Work
i.
Max. feeding work - set a lower number
ii.
Min. feeding pause - set a higher number
4.
Long or failed ignition:
a.
High chimney draft - Chimney draft is a major factor that can affect ignition cycle time. This time is normally 4
to 6 minutes. Chimney draft higher than 15Pa negatively affects the resulting ignition time. The solution is to
install a draft stabiliser. Also, keep in mind that the higher the boiler power, the more likely it is to affect the
ignition time.
We recommend installing a draft stabiliser with each boiler. In addition, the draft stabiliser must
be set as indicated in the boiler parameter table - chimney draft
.
b.
Quantity of pellets on the grate: Service menu, Feeder settings, Ignition
i.
Dose time - set a higher or lower number. The pellets should cover the opening of the igniter which is
above the grate, but in general, the fewer pellets on the grate during ignition, the faster the ignition
cycle.
c.
Poor fan speed: Service menu, Feeder settings, Ignition
i.
Fan speed 1/2 - set the fan speed lower or higher. A trained installer knows the recommended values.
