before opening or removing the boiler panels, turn the appliance off by
shutting off the gas tap.
Check
that the flue gases passage sections of the heat exchanger are not
obstructed. Use a wet soapy cloth to clean the external panels.
Do not
use abrasive solvents, powders or sponges.
Do not
clean the appliance or its component parts with highly flammable
substances such as : petrol, alcohol or heavy oil.
Check
electrode position and distance.
See Fig. 25
6 REMOVING THE CASING
To remove the casing:
- disconnect the appliance from the electric power supply using the om-
nipolar switch
- detach the display connector
See Fig. 26
- remove the two screws

safety is optimised. This would normally involve:
- removing any rust on the burners
- removing any build-up on the electrode
- cleaning the combustion chamber
- checking that the appliance switches on and off and operates correctly
- check the seal of the gas and water pipes and connectors.

The following instructions are addressed solely to qualified technicians authorised to work on the appliance.
FAULT
CAUSE
SOLUTION
No spark

tenance section)
The exchanger plates get dirty quickly
- Poor forced draught or dusty room
- Check exhaust flue efficiency
- Yellow flame
- Check type of gas and clean burner
- Excessive gas consumption
- Check and adjust
There is a smell of gas
- Caused by leaks in the pipe circuit. Check the
pipework to find the leak
- Do not use any electrical switches or any
object with a spark. Ventilate the room
