USE AND MAINTENANCE

3. 1 COMMISSIONING
THE BOILER
When commissioning the boiler it is
recommended:
– to make sure that the system has
been filled with water and adequa-
tely vented;
– to make sure that the flow and
return valves are fully open;
– to make sure that flue and chimney
are free from obstructions;
– to make sure that the electrical con-
nections t o t he mains and t he
earthing are correct;
– to make sure that no flammable
liquids or materials are near the
boiler.
3.2 LIGHTING AND
OPERATION
3.2. 1 Lighting the boiler
To light the boiler proceed as follows
(fig. 10):
– check that the "Testing Certificate"
has been removed from inside the
combustion chamber;
– switch on the main switch (1); the
burner will start ;
– turn the boiler stat knob (5) to the
desidered setting.
For best results, set the boiler stat
knob to a temperature no lower
than 60°C to prevent the formation
of condensate.
The set temperature value can be
checked on the thermometer (4).
3.2.2 Safety stat

immediately turning off the burner
when the boiler accidentally overheats.
To restore normal operations, wait
until the temperature drops below the
thermostat calibration setting.
3.2.3 System filling
Periodically check the pressure values
of the hydrometer (3 fig. 10) which,
when the system is cold, should range
between 1 and 1.2 bar. If the pressure
is less than 1 bar, reset the system.
3.2.4 Turning OFF boiler
To turn off the boiler, cut off the volta-
ge by pressing the mains switch (1
fig. 10).

CLEANING THE BOILER

The boiler body and flue should be
cleaned at the end of each season.
To clean the boiler, simply remove the

burner-holding plate and the cleaning
plate with their insulation and protec-
tion panels; this operation gives easy
access to the three front pockets and
the combustion chamber.
Before proceeding to clean the and
"2R6 ÷ 2R9" models, the baffles must
be removed (fig. 11).
Once maintenance has been comple-
ted, reposition the baffles.
Use the pig (fig. 11) to clean the
smoke pipes.
NOTE:
Preventive maintenance must be
carried out by authorized technical
staff.

USER WARNINGS

When faults occur and/or the equip-
ment does not operate correctly, turn
it off, without attempting to make any
repairs or take direct action.
For any operation only contact the
authorised technical personnel in your
