Servicing
Maintenance
Burner and boiler servicing must only
be carried out by a professional
heating engineer trained in these
operations. The system operator is
advised to take out a maintenance
contract to guarantee regular
servicing. Depending on the type of
installation, shorter maintenance
intervals may be necessary.
• Before all maintenance and cleaning
work,
switch off all electrical power
supplies (7P separate
motor power supply).
• Use original spare parts.
Checking the combustion
components
• Remove the burner hood.
• Remove the two screws
W
from the
cover.
• Remove the combustion components.
• Check the ignition electrodes and the
ignition cables; replace if necessary.
• Clean the turbulator.
• Check adjustments and settings
during assembly.
Removing the plate
• To do this, unscrew but do not remove
the 2 screws
X
securing the motor plate.
• Turn the plate (bayonet system),
carefully remove it and hang it in the
maintenance position (see
illustration).
• Clean the housing, fan wheel and
recirculation unit, and check that they
are not damaged.
• If necessary to clean it, remove the air
recycler; to do so, remove the screw
Z
then unclip it.
• Clean the turbine and check it is not
damaged.
Fitting the fan wheel
When changing the motor or the fan
wheel, refer to the positioning diagram
opposite. The internal flange
A
of the fan
wheel must be aligned with plate
B
.
Insert a ruler between the vanes of the
fan wheel and bring
A
and
B
to the same
height. Tighten the cone-point screw on
the fan wheel.
