Question Answer Explanation
Why is the fuel burning in the
boilers with automatic
feeding? It is due to bad feeding times. Blower settings are wrong. Adjust fuel feeding and/or the blower (see the setting table).
Call the helpline.
Why is there sinter on the
burner? Sinter is made by excessive air infeed. Regulate the blower operation.
What does alarm mean –
excessive flue gas
temperature ? Clean boiler means that the boiler's exchanger may be dirty.
Flue gas temperature greater than 280
o
C.
Clean the boiler's exchanger.
Reduce fuel feed
Why does the unburnt pellet
fall into the ash tray? Because the pellet feeing rate or ventilation are too big. Lower the feeding by 2-3% and check for improvement, if necessary, repeat the procedure.
Lower the ventilation by 2-3% and check for improvement, if necessary, repeat the procedure.
What does the „feeder
overheat” mean? The overheated feeder can mean that the fuel bin door is
open. The seal under the bin is broken. The cleaning hatch seal
is broken. The seal between the burner and feeder pipe is
broken. Loose screws on the connections of the basket
between the feeder and burner. Close the fuel bin door
Replace the seal under the bin door.
Replace the seal under the basket.
Replace the seal.
Tighten all the screws.
What does the „boiler
overheat” alarm mean? The boiler overheats when the temperature exceeds 90 o C
(usually when the upper grate is in operation).
The hold time is too short.
Cool down the boiler, remove the fuel if necessary.
Increase the hold time.
What does the „fumes sensor
damaged” alarm mean? It means that the fumes temperature has exceeded 250 o C.
The fumes temperature sensor is broken.
Lower the fuel feeding. If the fuel is burnt on the burner and grate simultaniously, feed less fuel to the grate.
Replace the fumes temperature sensor.
Smoke coming from the boiler
door. It means that there is no draught. Tighten wall in the connection between the flue pipe and the chimney.
Check if the patency of the chimney, and its parameters are as recommended by the manufacturer.
Seal the outlet of the boiler to the chimney vent, preventing the suction of cool air.
If the chimney diameter is too small, you can install an extraction fan.
There is water coming from
the convection channels. The fuel used is wrong or the humidity is too high.
Combustion temperature is too low.
Too little air feed.
Fumes throttle is closed.
Controller is set incorrectly. Use fuel of proper energy value and humidity.
Open the air throttle.
Open the fumes throttle.
Set the controller right.
During the initial start-ups the
boiler „sweats”. It is due to condensation. Heat the boiler above 80 o C and keep this temperature for at least 6 hours. If necessary, repeat.
Why is the fuel combustion so
rapid? The chimney diameter is too big.
Air flow is too high.
Controller set is incorrect. Close the throttle on the flue.
Check the sealant on the door.
Regulate the airflow. Regulate the controller or call the helpline.
What features does the
microprocessor regulator
have? The controller provides:

automatic ignition
 weather control
 room control (room temperature)

central tap water pump regulation

clock regulation of the circulation pump, additional pump,
burner (boiler operation time)

extinguishing

control via Lambda sensor.
