There is no spark be-
tween electrodes of the
igniter
• The electrodes of igniter is polluted
• Electrical connection between igniter and
automation is broken
• Spark interval is too large
• Automatic control went wrong
• The ceramic on ignition elektrode is broken,
• Clean electrodes
• Check electrical connection
between ingnition module and auto
• Check spark interval
• Please change the ignition and
ionization electrode
• Replace automatic control
Ignition cycle is fin -
ished normally
Appliance does not oper-
ate after the first ignition
cycle
• The gas supply valve is turned off
• Air is not removed sufficiently from
aspipe
• Nozzle pressure is not suitable
• Turn on the gas supply valve
• Remove the air from the pipe
• Check the input and output pres-
sure on the solenoid valve
Ignition cycle is fin -
ished normally
Appliance does not oper-
ate after the first ignition
cycle
• Solenoid valve went wrong
• Uncertain connection between ignition
module and automatic control
• Nozzle pressure is not suitable
• Replace the solenoid valve
• Replace the differential switch
• Check the input and output pres-
sure on the solenoid valve
The ceramic burner ig-
nites but stops soon
• The phase and null are replaced
• Nozzle pressure is not suitable
• The ceramic plates are contamined
• The Ignition electrode is touching the
catalitic grid
• Check the wires connection points
• Check the input and output pres-
sure on the solenoid valve
• Please clean all the cearamic pla-
tes. (compressed air is required)
• Please remove, and keep some
distance from the catalitic grid (at least
2 mm)
The unit is working, but
the efficiency, as also
the temeperature of the
ceramic plates are lower
as the normal opeatin
condition
• Nozzle pressure is not suitable
• The ceramic plates are contamined
• Please clean all the cearamic plates.
(compressed air is required)
• Check the input and output pres-
sure on the solenoid valve
Appliance operates but
the combustion is une-
ven and noisier than it
should be
• Nozzle pressure is not suitable
• Check the input and output pres-
sure on the solenoid valve
By using a manual ignition
unit. after the ignition pro-
cess the thermocouple do
not stays open.
• Faulty thermocouple
• The thermocouple is contamined
• Please change the thermocouple
• The disamble and cleaning of the
thermocouple
