Preparing boiler operation for emergency burning wood
When switching from pellet burning to fire wood burning mode, carry out the following adjust
-
ments. Dismantle the burner and take measures so that it cannot start operating outside the boiler
drum
(disconnect it from the power supply)
. Close the opening (which remains after the burner was
removed) by the supplied lid. Set required temperature of water exiting the boiler (80 - 90 °C) on the
FR 124 draught regulator so that it effectively regulates air flap-valve at the back sid of the boiler. This
air flap was closed during the pellets burning mode.
CAUTION
- When switching the boiler operating mode from wood burning to pellets or
the other way round, clean the boiler thoroughly from ash, pay particular attention to the
tube heat exchanger on the top, heatproof shaped piece – upper spherical chamber and rear
flue-gasduct (remove ash from the lower lid), so that blockage of waste gas may not occur.
Ignition and operation when burning alternative fuel - wood
First disconnect and remove the pellet burner and close the aperture by the supplied lid, then you can
ignite the wood. Open the upper loading door, place paper or wood wool on the bottom of the stoking
area, place dry splinters on top of the paper/wood wool, slightly pull out the ash-pan and ignite (close
the upper door). Set the required heating water temperature (80 - 90 °C) on the Honeywell draught regu-
lator. By wood heating turn the draught regulator (turnin clock wise) to the lowest value (50 °C) so that
the ventilator runs only when heating up for faster fire up. After loading fuel close the lower ash-pan.
The ash-pan must be retracted back in position during the boiler operation. Otherwise, the boiler output
cannot be regulated. Choose the amount of fuel which you load in by the required output.
Additional secondary air inlet placed under the door-
frame
In case of burning fire wood as an alternative fuel.
Loosen or even complete remove the sheet-metal with its seal-
ing, which covers the additional secondary air inlet placed under-
neath the door frame.
However, if the pellet burner is utilised for
the burning process, the opening for the additional secondary
air inlet must be properly closed and tightened
.
CAUTION
-
When loading fuel, do not exceed the lower edge of the doorframe.
All the
doors must be well closed when the boiler is in operation.
NOTE
- When igniting in the boiler for the first time, condensation and condensed fluid leak
-
age occurs – this is not a defect. Condensation will disappear later. When burning small par-
ticle wood waste, it is necessary to keep checking the waste gas temperature. Otherwise, the
ventilator (S) may sustain damage.
Wood tar and condensate formation in the hopper is a
side effect of wood combustion.
Is good to know when burning moist wood, the fuel con-
sumption increases, the boiler does not reach the required output and the service life of both
- the boiler and the chimney - decreases.
