3.3.1
Smoke side boiler (fig. 11)
To carry out cleaning of the smoke pas-
sages remove the screws that fix the
door to the body of the boiler and with the
special cleaning brush clean the internal
surfaces and the smoke evacuation tube
well, removing any deposits.
Once the maintenance is compled, the
baffles have to be fitted onto the original
positions.
The maintenance operations can be car-
ried out without removing the burner.
3.3.2
Fault finding
Herefater we outline a number of poten-
tial problems that may occur on the
appliance and the relevant list of actions
required.
A working fault, in most cases, provo-
cates the "lock out" signal onto the con-
trol panel of the control box.
When this light turns on, the burner can
operate again only after the reset button
has been pressed; if this has been done
and a regular ignition occurs, it means
the failure can be defined momentary
and not dangerous.
