Boiler body maintenance
Danger!
Before performing any maintenance, make
sure the boiler and its components have
cooled down.
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
precautions 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;
- extract the smoke turbulators;
- brush the smoke ducts energetically to remove any trace of
filth.
Check condition of gaskets and insulation fibres
The insulation fibre of the door can show cracks
after a short time of operation; this however 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 authorised
by its manufacturer (or else the warranty shall be terminated).
Checking ignition electrode
Burner maintenance must be carried out by personnel authorised
by its manufacturer (or else the warranty shall be terminated).
COMPONENT:
Ts (safety thermostat)
System expansion vessel
Door gaskets
Smoke chamber gaskets
Smoke turbulators
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?
Are the smoke turbulators in place and the
smoke ducts clean?
CONTROL/INTERVENTION METHOD:
Bring the boiler to operating temperature
with the pumps stopped.
Check the nitrogen pressure.
Pressurise the boiler (open the pump
bleeder). Open the heating circuit closing
valves.
Further tighten the door screws.
Replace the sealing gasket and, if needed,
the internal gasket of the door.
Further tighten the smoke chamber locking
nuts.
Replace the sealing gaskets.
Perform a general cleaning with the supplied
brush.
