9 After performing the necessary maintenance operations, the
original adjustments must be restored and the combustion prod-
uct analysis must be performed to check the correct operation.
9 Do not clean the appliance or any latter part with flammable sub-
stances (e.g. petrol, alcohol, etc.).
9 Do not clean panelling, enamelled and plastic parts with paint
solvents.
9 Panels must be cleaned with ordinary soap and water only.
Burner cleaning
The flame side of the burner is made with an innovative material
of the latest generation.
• Be especially careful during the dismantling, handling and installa-
tion of the burner and the components next to it (e.g.. electrodes,
insulation panels, etc.).
• Avoid direct contact with any cleaning device (e.g. brushes, va-
cuum cleaners, blowers, etc.).
In general, the burner does not require maintenance, but particu-
lar cases may occur where cleaning is necessary (e.g.. distribution
network of gas containing solid particles and in the absence of a
filter on the line, suction air containing excessively adhesive parti-
culates, etc.).
For this reason, perform a visual control of the burner in order to
ensure the proper functioning of the product:
• remove the front cover of the air box
• unscrew the fastening nut of the gas train to the valve, remove the
gas train spring clip to the mixer and turn the gas train outwards
• remove the silencer from the mixer
• disconnect the connectors of the wiring from the fan and the con-
necting cables of the electrodes
• unscrew the fixing screws and remove the exchanger-fan cover
assembly from its seat
• unscrew the fixing screws and remove the burner from its seat
checking it condition
9 If necessary, clean the burner with compressed air, blowing
from the metal side of the burner.

9 It is possible that with ageing, the fibres constituting the
flame side of the burner can tone the colour.
• Reassemble everything in reverse order.
9 If necessary, proceed with the replacement of the sealing
gaskets.
The manufacturer declines all responsibility for any damage caused
from the failure to observe that stated above.
