Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
4.3. Boiler ignition
1. Switch on the controller (see: Boiler controller operation
manual) and activate manual work mode,
2. Check operation of individual devices: fan, feeder, central
heating pump activation,
3. Fill the hopper with a proper fuel and close tightly,
4. Switch on the fan. The feeder starts to supply fuel for approx.
2-3 minutes in manual mode. Wait until the fuel appears on
the cast-iron burner grate.
5. Ignite fuel using wood chips placed manually on the grate.
6. After ignition, set proper parameters on the controller (boiler
operation temperature, feeding time, feeding pause time
and blow-in force), according to the values speci
fi
ed in the
controller and feeder operation manual.
CAUTION! Burner door must be tightly closed in the auto-
matic boiler operation mode.
CAUTION! Do not set boiler temperature above 57°C!
It increases the possibility of “dew point” appearance,
which accelerates low-temperature corrosion of the heat
exchanger. Maintaining water supply temperature below
57°C when using inappropriate solid fuel types leads to
intensi
fi
ed boiler wear and lowers the its e
ffi
ciency.
After boiler ignition, entire control of the combustion process
is taken by the controller (see. Controller instruction manual)
that maintains the set water temperature in the boiler with ref-
erence to the heat demand of the building.
4.4. Approximate parameters of the controller
The controller is pre-con
fi
gured, but its input parameters
change depending on the fuel used and may require individual
adjustment. Any adjustments shall be made depending on the
heat demand, type and quality (calori
fi
c value) of coal, or de-
pending on the size of the heating system.
Setting appropriate parameters ensures economic fuel con-
sumption. The adjustment consists in setting the feeding pause
proper for the heat demand. If the boiler does not reach the set
temperature, the feeding pause must be gradually shortened,
increasing the blow-in force. In the opposite situation, when the
boiler reaches the set temperature easily or starts to discharge
unburnt fuel, the feeding pause must be extended to provide
more time for fuel combustion, and the blow-in force must be
reduced accordingly. The blow-in force shall be adjusted based
on
fl
ame observation. Properly adjusted blow-in force gives
bright-yellow
fl
ame. Too weak blow-in force results in red
fl
ame
and occurrence of black smoke. Excessive blow-in force results
in short white
fl
ame.
