TROUBLESHOOTING
Problem
Cause
Solution
The lamps of the
control panel do not
light
- no electrical supply to the lamp
- the control panel is not connected
to electricity
- lamp defect
- electric cable defect
- check/replace the lamp
- connect to electricity
- check/replace the cables
The boiler does not
reach set
temperature
- fan blocked
- air passages are blocked
- boiler is not cleaned
- incorrect boiler start-up
- insufficient water in the system
- too big pump debit
- boiler under dimensioned
- bad quality fuel used
- insufficient chimney draught
- check/replace the fan, check the
function of the fan regulator and
thermostat
- clean the air passages
- clean the boiler
- start the boiler correctly
- fill the system
- regulate the pump speed
- change the fuel used
- check/clean the chimney
High temperature in
the boiler, but low
temperature at the
radiators
- too high hydraulic resistance in the
heating network
- thermostatic mixing valve is
connected wrong
- increase the pump speed
- check/replace the mixing valve
Condensation
formation in the fire
chamber
- too big boiler power
- too low return temperature in the
boiler
- fuel with excessive humidity
- load less fuel in the chamber
- install a return protection
system/thermostatic valve
- change the fuel used
Smoke coming out of
the doors
- boiler doors not regulated
- defect sealing cord of the door
- insufficient chimney draught
- too high air supply by the fan
- regulate the doors so that the
sealing cord stays tight
- check/replace the sealing cord
- check/clean the chimney
- reduce the air speed
Smoke coming back
to the silo
- chimney not cleaned/blocked
- fire tubes blocked, boiler not
cleaned
- furnace air holes blocked
- insufficient air supply and
ventilation of the boiler room
- too low flame and fuel level
- bad air regulation
- wrong fuel ignition
- bad chimney connection/
insufficient chimney draught
- damaged sealing
- check the chimney, clean it
- clean the boiler and the tubes
- clean the furnace and the air
holes
- check the air supply and
ventilation
- regulate correctly the fuel feeding
- check the ignition procedure
- check the chimney connection
and draught
- check all the connections sealing,
do not leave the silo lid open
while in function
The fan does not
function or it makes
a lot of noise
- set temperature reached
- disconnected by safety thermostat
- capacitor/motor defect
- bad electrical connection of the fan
- correct boiler function
- reset manually
- check/replace the fan
- check the electrical connection of
the fan
The feeder does not
function/fuel not fed
to the furnace
- feeder blocked from obstacle
- feeder is burnt or damaged
- no electricity to motor
- damaged motor/reducer
- connection pin broken
- remove the axes and the
obstacle
- bad combustion regulation/bad
chimney draught
- replace feeder
- check the electrical connections
-replace the motoreducer
- replace the connection pin
