REMEDY
The burner does not start-up
No electrical power
Control the power supply line fu-

not form and it therefore blocks
The gas valves do not open
Check valves functioning
There is no discharge between the
points of the electrodes
Check ignition transformer fun-
ctioning and the positioning of the
electrode points
No air pressure switch consent
Check calibration and functioning
of the air pressure switch
The burner starts, the flame forms
and it therefore blocks
No or insufficient flame detection
by the control electrode
Check the positioning of the con-
