FAILURE
CAUSE
TROUBLESHOOTING
1.
In case the burner is
mounted to a hot
water boiler and the
temperature in the
heated premises is
too low
Insufficient heating
output
It is necessary to adjust the burner’s heating output level.
The assigned
temperature is low
It is necessary to check the circulations water
temperature assignment in the burner’s control module.
Low temperature
assignment by the
room thermostat (if
connected)
It is necessary to increase the room thermostat
temperature assignment.
2.
In case the burner is
mounted to a hot
water boiler and the
temperature in the
heated premises is
too high
Heating
output,
exceeding
the
consumption
It is necessary to increase the burner’s heating output
level.
The
assigned
temperature is high
It is necessary to decrease the assigned temperature
High temperature
assignment by the
room thermostat (if
connected)
It is necessary to decrease the room thermostat
temperature assignment
3.
The burner is
switched ON but
there is no burning
process
No assignment for
operation
Check the assignment for operation by the burner’s
control module.
4.
Difficult pellets
ignition
The pellets are with
low quality
It is required to change the fuel, as its water content is
probably higher by the values needed for normal
operation of the appliance.
5.
The fuel ignition is
accompanied by
abnormal noise
Insufficient chimney
draught
It is necessary to check the condition of the chimney and
of the appliance, to which the burner is mounted and to
clean the ash deposits. After cleaning it might be
necessary to adjust the operational parameters of the
system – ask for servicing assistance.
6.
Overheating of the
appliance, to which
the burner is
mounted
No heating load or
incorrectly adjusted
heating output level
of the burner, or of
the heat energy
consuming appliance
Check the heating system - burner - appliance for correct
operation and eventually adjust the operation parameters
– to be performed by servicing specialist.
After the consuming appliance cools down and the failure
has been removed deactivate the emergency thermostat
(unscrew the protection cover cap, press the button and
screw the cap back), after that restart the burner.
7.
No fuel ignition
No pellets in the fuel
hopper
The hopper from which the burner’s transport auger
intakes fuel must be refueled.
No pellets in the
burner’s combustion
chamber
The process of primary fuel ignition can be restored by
restarting the pellet burner.
Presence of non-
ignited or burned
pellets over the
burner’s fire-grate,
but there is no
burning process
Clean the gathered fuel from the burner’s fire-grate.
If the ignition heating element is damaged or inactive it
must be replaced.
Incorrect operation of
the burner’s photic
sensor,
which
monitors the burning
process
The photic sensor for monitoring of the burning process
has to be re-adjusted or replaced – to be performed by a
servicing specialist.
