Malfunctions may occur even when the appliance is used correctly.
Burner fails to light (message "burn" appears on display TM ,
see "Instructions for use" chapter 5).
Possible causes:
- The ignition electrode is incorrectly positioned or the insulation
is damaged. The optimum distance from the outside of the
electrode to the boiler burner is approximately 5 mm(8mm Mod.
20 GN1/1), while the equivalent distance for the convector burner
is approximately 4.5 mm.
- The ignition / flame control device is damaged.
- The ignition electrode high tension lead is broken or shorting
to ground.
- Insufficient gas pressure.
- Faulty gas valve.
- Burner fan unit damaged, insufficient air pressure in combustion
chamber.
- Electronic control panel is damaged.
- Blown fuse, check electrical diagram.
- Oven chamber temperature probe damaged (error EPt1 - see
