2.1 BOILER ROOM
The boiler room should feature all the
characteristics required by standards
governing liquid fuel heating systems.
2.2
BOILER ROOM DIMENSIONS
Position the boiler body on the foundation bed, which should be at least 10
cm high. The body should rest on a
surface allowing shifting, possibly by
means of sheet metal.
Leave a clearance between the boiler
and the wall of at least 0.60 m, and
between the top of the casing and the
ceiling of 1 m (0.50 m in the case of
boilers with incorporated D.H.W. tank).
The ceiling height of the boiler room
should be less than 2.5 m.
2.3 CONNECTING UP SYSTEM
When connecting up the water supply
to the boiler, make sure that the specifications given in fig. 1 are observed.
All connecting unions should be easy
to disconnect by means of tightening
rings.
A closed expansion tank system
must be used.
2.3.1 Filling the water system
Before connecting the boiler, thoroughly flush the system to eliminate
scale which could damage the
appliance.
Filling must be done slowly so as to allow
any air bubbles to be bled off through the
air valves. In closed-circuit heating
systems, the cold water filling pressure
and the pre-charging pressure of the
expansion vessel should be no less than
or equal to the height of the water head
of the installation (e.g. for water head of
5 metres, the vessel pre-charging pressure and installation filling pressure
should be at least 0.5 bar).
2.3.2
Water system
characteristics
Water supplying the heating circuit
must be treated in accordance with
UNI-CTI 8065 standards.
It is absolutely essential to treat water
in the heating system in the following
cases:
–for extensive systems (with high
contents of water);
–frequent addition of water into the
system;
– should it be necessary to empty the
system either partially or totally.
2.4 CONNECTING UP FLUE
The flue is of fundamental importance
for the proper operation of the boiler;
if not installed in compliance with the
standards, starting the boiler will be
difficult and there will be a consequent
formation of soot, condensate and
encrustation.
The flue used to expel combustion products into the atmosphere must meet
the following requirements:
–
be constructed with waterproof
materials, and resistant to smoke
temperature and condensate;
–be of adequate mechanical resilien-
ce and of low heat conductivity;
–be perfectly sealed to prevent coo-
ling of the flue itself;
–be as vertical as possible; the termi-

nal section of the flue must be fitted
with a static exhaust device that
ensures constant and efficient
extraction of products generated by
combustion;
–to prevent the wind from creating
pressure zones around the chimney
top greater than the uplift force of
combustion gases, the exhaust
outlet should be at least 0.4 m
higher than structures adjacent to
the stack (including the roof top)
within 8 m;
–have a diameter that is not inferior
to that of the boiler union: square or
rectangular-section flues should
have an internal section 10% greater than that of the boiler union;
–the useful section of the flue must
conform to the following formula:

–1.00 m for each metre of
union itself.
2.5 BOILER BODY ASSEMBLY
The boiler body comes supplied assembled. Where there is difficulty in gaining
access to the boiler room, the body can
be supplied in separate sections. For
assembly, proceed as follows:
–prepare the sections, cleaning the
seats of the tapered nipples with
solvent;
– insert the bead of putty (fig. 5) in the
groove provided for fume tightness,
pressing lightly;
– prepare one of the two intermediate
sections. After lubricating them with
boiled linseed oil, insert the tapered
nipples (fig. 6);
–prepare the head, proceeding as
above, and bring it up to the intermediate section. Add only one section at a time;
–
assemble the sections, using the
tools provided consisting of a pair of
staybolts for assembly with the corresponding accessories (code
6050900 - fig. 7), exerting pressure
simultaneously on the top hub and
on the bottom hub. If, during this operation, the sections were to slot
together in such a way as not to be
even and parallel, slide a chisel in the
tighter side and, by applying a little
force, bring the two pieces together
so that they are parallel.
The sections can be considered properly joined together when their
outer edges come into contact;
– insert the bead of putty in the groo-
ve of the section that has just been
assembled, and then proceed to joining up the other sections until the
body is completed.
NOTE: befo re proceeding to connect the system, test the boiler
block with a water pressure of 7.5
bar.
2.6 FITTING THE CASING
The casing and the control panel are
supplied in separate cardboard packages. The housing package also contains the boiler documents and the
glass wool for insulating the cast iron
body. To fit the casing, proceed as follows (fig. 8):
– fix the left front side angle bar (2)
and the right front side angle bar (3)
to the upper tie rods using the two
galvanized nuts provided;
– place the front cross bar (4) on the
lower tie rods before securing the
angle bars with the two cap nuts

–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
The safety stat with automatic reset
calibration set at 100°C (2 fig. 11)
trips, 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. 11) 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 voltage by pressing the mains switch (1
fig. 11).
3.3 CLEANING THE BOILER
(fig. 12)
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 protection panels; this operation gives easy
access to the three front pockets and
the combustion chamber.
Before proceeding to clean the and
“1R 6 - 2R/2R GT 6 ÷ 9” models, the
baffles must be removed.
Once maintenance has been completed, reposition the baffles.
Use the pig to clean the smoke pipes.
NOTE: Preventive maintenance must
be carried out by authorized technical staff.
3.4 USER WARNINGS
When faults occur and/or the equipment 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
area.

room at the set level via the regulating knob.
– Push the “Continuous Operation” button .
–Regulate the room temperature with the
regulating knob.
TO SET THE STANDBY MODE
(when the user is away for a long period of time)
The standby mode keeps the temperature of the room at
the level of antifreeze protection.
– Push the “Standby mode” button .
MEANING OF THE SYMBOLS
On the display a few of the symbols indicate the current operating state. The appearance of a line under one of these
symbols signals that the corresponding operating state is
“active”.
Heating at the nominal temperature
(regulating knob)
Heating at reduced temperature (line ).

dows completely.
–In the rooms that are not used place the regulating valve
in the antifreeze position.
–Leave the space in front of the radiators free from
obstructions (remove furniture, curtains...).
– Close windows and blinds to reduce
dispersion of heat.
