Inspections and maintenance
Boiler body maintenance
Danger!
Before performing any maintenance, make
sure the boiler and its components have co-
oled off.
Disconnect the boiler from the electric mains
and shut the gas supply to the appliance.
Attention!
Before cleaning the boiler body, protect the
panel board against any water sprays.
Once a year, at the end of the heating season, the boiler must
receive a general cleaning.
Before performing any maintenance, make sure that all the pre-
cautions referred to in the previous point have been taken.
To proceed with maintenance you must:
- disconnect power by acting on the main switch;
- remove the burner, which could be overhauled at the same
time;
- open the furnace door to access the combustion chamber;
- remove the smoke chamber access door;
- make sure the internal parts are intact.
Checking status of gaskets and insulation fibres
The insulation fibre of the door can show
cracks after a short time of operation; this howe-
ver does not reduce its insulation capacity nor
jeopardise its lifespan. Check the condition of
the seal gasket which must not show signs of
deterioration; if so, it must be replaced, using
only original spare parts.
Check the condition of the smoke chamber inspection cover
gasket.
Replace it if worn, using only original spare parts.
Maintenance of burner
Burner maintenance must be carried out by personnel autho-
rised by its manufacturer (or else the warranty shall be termi-
nated).
Checking ignition electrode
Burner maintenance must be carried out by personnel autho-
rised by its manufacturer (or else the warranty shall be termi-
nated).
COMPONENT:
Ts (safety thermostat)
System expansion vessel
Door gaskets
Smoke chamber gaskets
VERIFY:
Does the thermostat place the boiler in
safety when overheating?
Does the vessel contain the right amount
of air?
Does smoke seep through the door
gaskets?
Does smoke seep through the smoke
chamber gaskets?
CONTROL/INTERVENTION MEASURE:
Bring the boiler to operating temperature
with the pumps stopped
Check the nitrogen pressure.
Pressurise the boiler (open the pump ble-
eder). Open the heating circuit closing val-
ves.
Further tighten the door screws.
Replace the sealing gasket and possibly
the internal gasket of the door.
Further tighten the smoke chamber nuts.
Replace the sealing gaskets.
