IMPORTANT
This INSTRUCTION MANUAL, which is an integral and indispensable part of the product, must be handed over to the user by the plumbers and
must be kept in a safe place for future reference. The manual must be handed over with the boiler should it be sold or transferred.
This boiler must be used for the purposes for which it has been designed. Any other use shall be considered incorrect and therefore
dangerous.
The boiler must be installed in compliance with applicable laws and standards and according to the manufacturer’s instructions given in this
manual. Incorrect installation may cause injury to persons and/or animals and damage to property.The manufacturer shall not be held liable for any
such injury and/or damage.
Damage and/or injury caused by incorrect installation or use and/or damage and/or injury due to non-observance of the manufacturer’s instructions
shall relieve UNICAL from any and all contractual and extracontractual liability.
Before installing the boiler, check that the technical data corresponds to requirements for its correct use in the system.
Check that the boiler is intact and that it has not been damaged during transport and handling. Do not install equipment which is patently damaged
and/or faulty.
Do not obstruct the air suction and/or heat dissipation grates.
Only original accessories must be used for all boilers supplied with optionals or kits (including electrical ones).
Dispose of the packaging with care as all the materials can be recycled. The packaging must therefore be sent to specific waste management
sites.
Keep the packaging out of the reach of children as it may represent a choking and suffocation hazard.
In the event of failure and/or faulty functioning, switch off the boiler. Do not attempt to make repairs: contact qualified technicians.
Original parts must be used for all repairs to the boiler.
Non-observance of the above requirement may jeopardize the safety of the boilers and expose people, animals and property to danger.
To guarantee efficiency and correct functioning of the equipment it is legally binding to service the boilers once a year according to the
schedule indicated in the relative section of this manual.
In the event of long periods of inactivity of the boiler, disconnect it from the power mains and close the gas tap (Warning! In this case the boiler’s
electronic anti-freeze function will not be operative).
Should there be a risk of freezing, add anti-freeze: it is not advisable to empty the system as this may result in damage; use specific anti-freeze
products suitable for multi-metal heating systems.
N.B.
For boilers which use gaseous fuel, if you smell gas:
- do not turn on or off electrical switches and do not turn on electrical appliances;
- do not ignite flames and do not smoke;
- close the main gas tap;
- open doors and windows;
- contact a Service Centre, qualified installer or the gas supply company.
Never use flames to detect gas leaks.
WARNING
This boiler has been built for installation in the country indicated on the technical data plate: installation in any other country may be a source
of danger for people, animals and property.
Read the warranty conditions and clauses on the warranty certificate attached to the boiler with care.
‘’WATER TREATMENT IN C.H. SYSTEM FOR CIVIL USE’’
NOTE FOR INSTALLER AND USER
1) The frequency of the cleaning of the D.H.W. heat exchanger is related to the hardness of the feeding water.
2) With a water hardness higher than 28°f (16°d) the use of antiscaling devices, whose choice will be made on the base of water characteristics, is
suggested.
3) To increase the resistance to the scaling, a D.H.W. temperature adjustment very close to that one of the actual use, is suggested.
4) The adoption of a modulating room thermostat reduces the scaling danger.
5) We advise you to verify the state of cleaness of the D.H.W. heat exchanger at the end of the first year and subsequently every two years.

2.2.2 - POSITIONING THE BOILER
When choosing the position of the boiler:
- refer to the indications given in the section
“Flue gas exhaust system “.
- remember that it is advisable to leave a
space of 50 mm on each side of the boiler
to facilitate maintenance operations.
- check that the walls are suitable.
- avoid fixing the boiler to thin partitions.
- avoid installing the boiler above applian-
ces which might affect operation when in
use (cookers which produce greasy ste-
am, washing machines etc.)
- avoid installing natural draught boilers in
corrosive or very dusty atmospheres such
as hairdressers’, laundrettes etc. as the life
of the boiler components could be signifi-
cantly shortened.
- 350 mm free space must be left between
the top of the boiler and the ceiling to allow
replacement of the magnesium anode.This
condition is met when there is a space of
436 mm between the axis of the holes in
the boiler bracket and the ceiling.
C = D.H.W. outlet 1/2"
F = D.C.W. inlet 1/2"
G = Gas inlet 3/4"
M = Heating system flow 3/4"
R = Return from system 3/4"
2.2.3 - ASSEMBLING THE BOILER
Before connecting the boiler to the D.H.W. and
heating system pipes, carefully clean the pi-
pes to remove all traces of metal resulting from
processing and welding operations as well as
any oil and grease which could damage the
boiler or jeopardize its operation.
NB: Do not use solvents which could damage
the components.
Unical declines all liability for injury to per-
sons and animals or damage to property
resulting from non-observance of the abo-
ve.
To install the boiler:
- fix the template to the wall;
- make four, Ø 10 holes in the wall for the
dowels and insert the hooks;
Warning! Rispect the minimum distan-
ce between hook and ceiling (436 mm).
- position the junction points for the connec-
tion of the gas supply pipe, cold water sup-
ply pipe, D.H.W. outlet, CH flow and return
by using the mounting jigs (lower part);
- fit the boiler onto the support hooks;
- join the boiler and supply pipes using the
pipe kit supplied;
- connect the boiler to the intake and outlet
system;
- connect to the power mains.

2.2.4 - VENTILATION
Boiler model IVEN B60 TN 24 have an open
combustion chamber and have been desi-
gned for connection to a chimney: the com-
bustion air is taken directly from the room
in which the boiler is installed.
The boiler must be installed in a suitable room
pursuant to applicable standards and laws
which shall be considered as having been
transcribed in full in this manual.
2.2.5 - FLUE GAS DISCHARGE
SYSTEM
NATURAL DRAUGHT BOILER
Connection to the chimney
The chimney is indispensable for the correct
functioning of the boiler; it must therefore con-
form with the following requirements:
- it must be made from waterproof material
and be resistant at the temperature of the
flue gas and relative condensate;
- it must have sufficient mechanical stren-
gth and low thermal conductivity;
- it must be perfectly sealed to prevent co-
oling due to parasite air inlets;
- it must be as vertical as possible and the
end section must have a chimney cap whi-
ch guarantees efficient and constant remo-
val of the combustion products;
- the chimney must have a larger diameter
than that of the boiler’s draught stop; for
chimneys with a square or rectangular sec-
tion, the internal section must be 10% lar-
ger than the section of the connection duct
to the draught stop;
- starting from the draught stop, the duct fit-
ting must have a vertical section of more
than twice the diameter before joining the
chimney.
Direct emission into the atmosphere
Natural draught boilers can discharge combu-
stion products directly into the atmosphere
using a duct which goes through the outside
walls of the building connected to a flue
exhaust terminal.
The exhaust duct must also comply with the
following requirements:
- the sub-horizontal part inside the building
must be as short as possible (no more than
1.000 mm);
- for boiler with vertical discharge, such as
boiler IVEN B60 TN 24, there must be no
more than 2 direction changes;
- it must receive the discharge from a single
boiler;
- the part going through the wall must be pro-
tected by a sheath duct; the part of the
sheath duct facing the inside of the buil-
ding must be closed and the part facing
outwards must be open;
- the final section, on which the draught ou-
tlet will be fixed, must protrude from the
wall of the building for a length of a least
twice the diameter of the duct;
- the draught outlet must overlap the con-
nection to the boiler exhaust duct connec-
tion by at least 1.5 metres (see fig. 6)
Installation info
Boiler model IVEN B60 TFS 24 have a sea-
led combustion chamber with reference to
the environment in which it is installed, so no
special measures need be taken as regar-
ds ventilation for the combustion air.
This is valid also for the room the boiler will
be installed in.
The boiler must be installed in a suitable room
pursuant to applicable standards and laws
which shall be considered as having been
incorporated in full in this manual.
