TROUBLESHOOTING
SYMPTOMS
Number of flashes of lamp (8)
Fan is noisy or vibrates
Insufficient heating
In case of serious malfunction, the electronic equipment
causes the heater to go into safety stop, and lamp (#8 FIG. 5)
lights with a steady red light (stop light).
Warning
In case of a safety stop, you have to push the reset
button (#8 FIG. 5) for 3 seconds to restart the heater.
Warning
NEVER do more than two restarts in a row: unburned
fuel can accumulate in the combustion chamber and
suddenly flare up at the next restart.
In case of safety stop, press the reset button (#8 FIG. 5) for at
least 12 seconds to launch a self-diagnosis programme, after
which the button will flash at different rates (Self-diagnosis
lamp) according to the type of safety intervention: the synoptic
on the electrical panel shows the possible types.
If the combustion chamber overheats, the safety thermostat
(14) trips to shut off the burner and lamp (#8 FIG 5.) lights: to
reset the burner, you have to shut off the heater completely,
cut electrical power and push button (#14 FIG. 5).
Warning
You must always find the cause of the safety intervention
and remove it before pushing reset button (#8 FIG 5) or
button (#14 FIG 5) and restarting the heater.
If the heater is still not working properly, please contact your
nearest dealer or authorized Service Centre.
