3.1. Installation regulations
The heating unit is to be installed in accordance to applicable stan-
dards and laws, which are to be considered as incorporated in full
to this manual.
3.2. Installation
3.2.1. Packaging
The heating unit is packed in a sturdy wooden cage on a wooden
pallet. Once the wooden cage has been removed, check the hea-
ting unit to be intact. The packaging material is recyclable: and it is
to be disposed of in a specific waste management center.
Keep the packaging out of the reach of children as by its nature may
be hazardous.
The manufacturer shall not be held liable for injury to persons and
animals or damage to property resulting from non-observance of
the above instruction.
The packaging contains:
- installation, use and maintenance handbook,
- four screw-adjustable legs,
- oil filter, hose pipes and fittings for burner fuel supply.
3.2.2. Choosing where to install the heating unit
When choosing the position of the heating unit please take into ac-
count the following:
- it is advisable to provide a 50 cm clearance from each side of the
heating unit, in order to simplify service operations;
- avoid installing the heating unit in humid or dusty areas;
- the boiler room is to be un-accessible to non authorized person-
nel, children and animals.
3.2.3. Installing the heating unit
Before connecting the boiler to the DHW and CH system pipes,
carefully clean the pipes to remove all traces of metal resulting from
processing and welding operations as well as any oil and grease
which could damage the heating unit or alter its operation.
WARNING
Do not use solvents which could damage the components.
The manufacturer shall not be held liable for injury to persons
and animals or damage to property resulting from non-obser-
vance of the above instruction.
After placing the heating unit in the boiler room, and in order to in-
stall it, proceed as follows:
B and BV MODELS
- remove the two front panels by pulling them toward the outside;
- remove the two screws securing the base to the wooden pallet;
- in order to remove the wooden pallet from the heating unit, it is
necessary to raise it; proceed carefully: insert two 1” iron bars throu-
gh the openings underneath the chassis which supports the heat
exchanger, raise it without damaging the hydraulic components and
lower it to the floor;
- screw the four adjustable supporting legs in: adjust as necessary in
order to stabilize the unit;
- connect the heating unit to the DHW and CH flow and return pi-
pes;
- connect the unit to the chimney (and to the air intake pipe in TFD
versions);
- connect the heating unit to the power mains and, when available,
to the room thermostat (option).
- connect the burner to the fuel oil supply pipes (see paragraph
3.2.4);
R and RV MODELS
- remove the front panel by pulling it toward the outside;
- remove the two screws securing the base to the wooden pallet;
- in order to remove the wooden pallet from the heating unit, it is
necessary to raise it; proceed carefully: insert two ropes or cables
under the base front-rear wise, raise it and lower it to the floor;
- screw the four adjustable supporting legs in: adjust as necessary
in order to stabilize the unit;
- connect the heating unit to the CH flow and return pipes;
- connect the unit to the chimney (and to the air intake pipe in TFD
versions);
- connect the heating unit to the power mains and, when available,
to the room thermostat (option).
3.2.4. Connection to the fuel oil mains supply
Refer to paragraph 4.3 for instructions on connecting to the fuel oil
supply.
When heating units are installed in particularly cold areas, use fuel
oil with a low content of paraffin.
It may be necessary to install an additional fuel oil pre-heater.
It is mandatory to install the provided fuel oil filter.
3.2.5. Room ventilation
Heating units are designed for connection to a chimney.
The combustion air can be taken:
- directly from the room in which the unit is installed;
- from outdoor using 80 mm diameter pipes (D version).
N.B.
When the combustion air is taken from the room where it is
installed, the system must comply with applicable standards
and laws which are to be considered as fully incorporated to
this manual.
3.2.6. Air intake and flue gas discharge system
As far as the emission of flue gas into the atmosphere, it is manda-
tory to comply with all applicable standards and laws; they are to
be considered as fully incorporated in this manual.
The flue gas discharge pipes in the heating system have the fol-
lowing diameter:
- connection to 150 mm diameter flue gas discharge ducts (TF ver-
sions; type B23);
- connection to 120 mm diameter flue gas discharge ducts (TFD
versions; types B23, C53 and C83).
TF version (type B23)
Flue gas discharge ducts must be connected to a chimney system
designed in compliance with all applicable standards and laws, whi-
ch are to be considered as fully incorporated to this manual. When
the combustion air is taken from the room where the unit is installed,
the system must comply with applicable standards and laws.
The chimney system and flue gas pipes must comply with the fol-
lowing requirements:
- the diameter is not to be smaller than the heat-exchanger flue gas
discharge opening. In case of square or rectangular cross section
flue gas pipes, the diameter must be 10% larger than the opening
diameter of the heat exchanger.
- the pipes must be made with waterproof material, resistant to flue
gas temperature and acid condensate;
- they are to have low thermal conductivity, proper mechanical resi-
stance, perfect seal and appropriately calculated height and cross
section;
- vertical path (chimney system) and constant cross section without
any narrowing;
- the terminal is to ensure constant, efficient discharge of flue gas in
any atmospheric condition;
- the terminal must project at least 50 cm from any adjacent struc-
ture within a 5 meter radius.
