yearly maintenance must be performed by qualified personnel.
Should you decide not to use the appliance, parts entailing
potential sources of hazard must be made safe.
Before commissioning an appliance that has not been used,
wash the domestic hot water production system, making the
water flow until it has been fully replaced.
Should the appliance be sold or transferred to a new owner or
if you move and leave the appliance, always make sure that the
instruction manual accompanies it in order to be consulted by
the new owner and/or installer.
Only original accessories must be used for all appliances with
optionals or kits (including electric).
Incorrect installation or improper maintenance can cause damage to persons, animals or objects for which the manufacturer
is not responsible.
Before performing any cleaning or maintenance, disconnect the
appliance from the energy mains by acting on the switch of the
system and/or through the specific cut-off devices.
Do not obstruct the terminals of the intake/exhaust ducts.
In case of failure and/or malfunctioning of the appliance, switch
it off and do not try to repair it or intervene on it directly. Contact
only personnel qualified in compliance with law.
This appliance is intended solely for the use for which it was
expressly designed.
Any other use is to be considered improper and therefore dangerous.

1.5 - SAFETY WARNINGS
ATTENTION!
The appliance must not be used by people with reduced physical, sensory and mental abilities, without
experience and knowledge. These people must be previously trained and supervised during manoeuvre
operations. Children must be supervised so that they do not play with the appliance.
ATTENTION!
The appliance must be installed, adjusted and maintained by professionally qualified personnel, in compliance with the standards and provisions in force. Incorrect installation can cause damage to persons,
animals and objects for which the manufacturer cannot be held responsible.
DANGER!
The boiler must be serviced or repaired by professionally qualified personnel, authorised by Unical. We
recommend stipulating a maintenance contract.
Insufficient or irregular maintenance can jeopardise the operating safety of the appliance and cause damage
to persons, animals and objects for which the manufacturer cannot be held responsible.
Modifying parts connected to appliance
Do not modify the following parts:
- the boiler
- the gas, air, water and electricity supply lines
- the flue gas pipe, the safety valve and the exhaust pipe
- the construction parts which affect the operating safety of the appliance.
Attention!
To tighten or loosen the screwed fittings, use only appropriate fixed spanners.
Incompliant use and/or inappropriate tools can cause damage (e.g. water or gas leakage).
ATTENTION!
Indications for propane gas-fired appliances
Make sure that the gas tank has been deaerated before installing the appliance.
For state-of-the-art tank venting, contact the LPG supplier or person qualified in compliance with the law requirement.
If the tank has not been professionally deaerated, ignition problems could arise.
In that case, contact the supplier of the LPG tank.
Smell of gas
Should a smell of gas be perceived, follow these safety guidelines:
- do not turn electric switches on or off
- do not smoke
- do not use the telephone
- close the gas shut-off valve
- air out the area where the gas leakage has occurred
- inform the gas supplier or a company specialised in installation and maintenance of heating systems.
General information
Explosive and easily flammable substances
Do not use or store explosive or easily flammable materials (e.g. petrol, paints, paper) in the room where the appliance is installed.

1.6 - TECHNICAL DATA PLATE
The technical data plate is inserted in the document envelope. When installation is finished, it is MANDATORY that the
appliance installer apply it at the front top part.
If lost, ask the Unical Technical Assistance Service for a duplicate.
The serial number of the boiler is on the riveted plaque on the front plate of the body (front right top side).
If the identification plate is tampered with, removed or missing, the product cannot be safely identified, making any
installation and maintenance operation difficult.
CE marking
The CE marking certifies that the boilers meet:
- The essential requirements of the gas appliance directive
(90/396/EEC)
- The essential requirements of the electromagnetic compatibility directive (89/336/EEC)
- The essential requirements of the efficiency directive (92/42/
EEC)
- CE marking compliant to directives governing the use of
gas-fired appliances - Ts < 110°C.

TECHNICAL FEATURES
AND DIMENSIONS
2.1 - TECHNICAL FEATURES
One of the significant aspects taken into account when designing the TERNOx 2S series boilers is the reduction of the formation of pollutants in exhaust gases.
One of these consists of nitrogen oxides (Nox). In Europe, their
emission is governed by several legislative standards and provisions. Welding procedures and devices are approved and
certified according to EN Standards.
The main technical elements of the design are:
- An accurate study of geometries, to achieve an ideal ratio
between combustion volumes and exchange surfaces.
- The selection of the materials used to guarantee the long life
of the boiler.
Welding procedures and devices are approved and certified
according to EN Standards.
The boilers have pressurised combustion, with 3 flue gas passes with passing flame and wet inversion chamber.
The combustion gases produced by the burner, having passed
the combustion chamber of the furnace, enter the pipes in the
second flue gas pass.
2.2 - OPERATION PRINCIPLE
TERNOX 2S boilers have pressurised combustion, with 3 flue
gas passes with passing flame and wet inversion chamber.
The combustion gases produced by the burner, having passed
the inversion chamber of the furnace, enter the pipes in the
second flue gas pass.
After the exhaust gases return to the front of the boiler, they
again change direction and pass through the pipes of the third
flue gas pass towards the flue duct.
After the exhaust gases return to the front of the boiler, they
again change direction and pass through the pipes of the third
flue gas pass towards the flue duct.
This type of boilers achieves a high average yearly performance
and low content of harmful substances in the flue gas. Another
advantage of the three flue gas pass structure consists of the
fact that combustion products remain less time in high temperature areas, thus limiting harmful emissions of nitrogen oxides.
The boiler body is thermally insulated by the application of a
mineral wool mattress with a high insulation level to reduce
heat dispersion to extremely low levels. It is finished by aluminium sheets.
The combustion chamber is always pressurised while the burner is operating.
For the value of this pressure, see the TECHNICAL DATA table,
in the column Flue gas pressure drop.
The flue gas duct and the fitting to the flue must be implemented in compliance with Standards and Legislation in force, with
rigid ducts resistant to heat, condensation, mechanical stress
and airtight.
