1 INTRODUCTION
Dear Customer,
Thank you for having chosen our generator.
In your interests, we invite you to follow and observe the instructions in this manual to ensure the
highest level of efficiency and duration of the unit.
IMPORTANT: failure to observe the instructions in this manual will void the warranty condi-
tions.
2 SAFETY WARNINGS
IMPORTANT
For safety and for proper operation, carefully read this TECHNICAL MANUAL before installing and
starting the generator.
The manual is an integral and essential part of the generator and must accompany it from installation
until disposal. The generator must be used for the purpose for which it was strictly intended and any
liability by the Manufacturer for damages to people, animals or property due to lack of maintenance
or for improper use, is excluded.
Safety of the thermal power plant
For safety purposes, the qualified technical personnel in charge of running the system must consider the fol-
lowing requirements:
-Follow the accident prevention and environmental safety regulations in force.
-Ensure the generator installation in the thermal power plant complies with the standards in force.
-Ensure that the electrical and hydraulic system complies with the standards in force.
-Ensure that the boiler room complies with the standards in force and is sufficiently ventilated.
-Ensure that the boiler fumes are conveyed outside the thermal power plant through a flue compliant
with the standards in force.
-Ensure that the acidic condensation that may develop during system start-up, is evacuated outside
the thermal power plant after a neutralisation process in compliance with the standards in force.
-Ensure that there is no danger due to frost inside the thermal power plant.
System check
Before switching on the generator for the first time, a duly qualified technician must perform a check at the
central heating plant and update the system log once the check is over.
Periodic verifications
The generator must be periodically checked by a duly qualified technician (maintenance worker), who should
update the system log once the check is over.
Danger of explosion
Routine and extraordinary maintenance must be entrusted to professionally qualified personnel with the
purpose of promptly detecting any damage to the generator's pressurised body and the safety and control
accessories.
Danger deriving from the fuel
Sensing the presence of fuel in the thermal power plant, it is appropriate to follow the precautions below to
avoid the risk of explosions and fires:
-Do not smoke or cause sparks.
-Do not turn on lights or electrical devices in general (mobile phones).
-Open doors and windows.
-Close the fuel shut-off valve normally placed outside the thermal power plant.
-Disconnect the electrical power supply by using the switch normally placed outside the thermal power plant.

4
Danger of burns
During normal operation, the generator has hot parts that, upon accidental contact without suitable personal
protection, can cause serious burns. Potentially hot parts include:
-Accessories and valves connected to the generator.
-Door and smoke chamber.
Danger from fumes
An incorrect adjustment of the closing door or an insufficient draught in the flue can leave fumes inside the
thermal power plant, causing fatal intoxication deriving from carbon monoxide which, by its nature, is colour-
less and odourless. Therefore, ensure the generator is properly installed and adjusted and the presence of
ventilation openings in the thermal power plant are compliant with the regulations in force.
Repairs
Any generator repair must be carried out or authorised by the manufacturer in order to avoid risks to people
and property, as well as to prevent voiding the Warranty Conditions being . Generator maintenance must
be entrusted to competent personnel.
Spare parts
In order to ensure maximum safety and reliability, it is essential that all removable defective accessories and
parts are replaced with Original Spare Parts supplied by the Manufacturer.

GENERAL FEATURES
This steel boiler range features 3 gas passes with no flame inversion.
This design minimises the formation of nitrous oxides (NOx) caused by the high temperatures and long flame
stay times typical of traditional boiler furnaces.
Furthermore, the BT range boilers have been designed for low temperature operations (return at 35°C). For
this reason, a double tube and a special smokebox refractory protection are essential to maintain the high
temperature of parts in contact with combustion product, and without condensate production.
The boilers are classified as “high performance” boilers according to the regulations in force due to their extremely
high efficiency deriving from optimisation of heat exchange and complete insulation of the exposed surfaces.
The above picture is only for reference.

3 GENERAL WARNINGS
Each generator is provided with a manufacture plate that can be found in the envelope with the boiler
documents. The plate lists:
Serial number or identification code;
Rated thermal output in kcal/h and in kW;
Furnace thermal output in kcal/h and in kW;
Types of fuels that can be used;
Max operating pressure.
A manufacture certificate is also provided which certifies the hydraulic test positive performance.
The installation must be performed in compliance with the regulations in force by professionally qualified
personnel. The term “professionally qualified personnel” means persons with specific technical skills in the
sector of heating system components. Incorrect installation may cause damage to persons, animals or ob-
jects for which the manufacturer cannot be held responsible.
At the first start up, all regulation and control devices positioned on the control panel should be checked for
efficiency.
The guarantee shall be valid only upon compliance with the instruction given in this manual.
Our boilers have been built and tested in observance of EEC requirements and, as a consequence, CE-
marked. EEC directives are as follows:
Directive on Gas 2009/142/CE (Rif. EN 303)
Directive on Output 92/42/EEC
Directive on Electromagnetic Compatibility 2014/30/UE
Directive on Low Voltage 2014/35/UE
IMPORTANT: This boiler has been designed to heat hot water at a temperature less than the boiling tem-
perature at atmospheric pressure and must be connected to a heating plant and/or a domestic hot water
plant within the limits of its performance and output.

5 INSTALLATION
Before connecting the boiler, perform the following operations:
Thoroughly clean all the system pipes in order to remove any foreign matter that could affect correct op-
eration of the boiler;
Check that the flue has an adequate draught, that there is no narrowing of passages and that it is free
from debris; also check that other appliances do not discharge into the flue (unless designed to serve
several utilities). See the regulations in force.
5.1 THERMAL PLANT
5.1.1 ROOM BOILER
Current regulations must always be observed.
Premises in which boilers will be installed should be sufficiently ventilated and permit access for ordinary and
extraordinary maintenance operations.
5.1.2 FLUE
The smokestack must be dimensioned as to applicable regulations.

Ensure that the hydraulic pressure measured after the reduction valve on the supply pipe does not exceed
the operating pressure specified on the rating plate of the component (boiler, heater etc.).
As the water contained in the heating system increases in pressure during operation, ensure that its
maximum value does not exceed the maximum hydraulic pressure specified on the component rating
plate.
Ensure that the safety valve outlets of the boiler and hot water tank, if any, have been connected to an
exhaust funnel in order to prevent the valves from flooding the room if they open.
Ensure that the pipes of the water and heating system are not used as an earth connection for the
electrical system as this can seriously and very rapidly damage the pipes, boiler, heater and radiators.
Once the heating system has been filled, you are advised to close the supply cock and keep it closed so
that any leaks from the system will be identified by a drop in hydraulic pressure indicated on the system
pressure gauge.

5.3 ELECTRICAL CONNECTION
Electrical systems of thermal plants designed only for heating purposes must comply with numerous legal
regulations which apply in general as well as specifically to each application or fuel type.
5.4 OPTIONAL CONTROL PANEL
The control panel (optional) with the boilers is made of IP40 protection plastic material, and houses the
regulation and safety instruments:
KEY
1 NET WARNING LIGHT
2 1st BURNER SWITCH
4 CIRCULATOR SWITCH
7 BOILER THERMOMETER
8 1st ADJUSTMENT THERMOMETER
9 1st SAFETY THERMOSTAT
11 2nd ADJUSTMENT THERMOSTAT
The upper part of the control panel can be rotated to gain access to the terminal board and uncoil the ther-
mostat and thermometer capillaries. A copy of the wiring diagram is contained inside the control panel cover.
The regulation thermostats have an operating range from 60° to 100° and can be set by the user by means
of the front knob.
Safety thermostats has a fixed setting of 110°C and can be manually reset in accordance by law.
Circulator consent thermostat located inside the panel can be adjusted from 0°C to 90°C using a tool and
is factory-set at 50°C, while its differential deviation is 6°C. Thanks to this thermostat, the circulator is inac-
tive when the temperature is below 50°C to avoid dangerous exhaust condensation.
For correct installation, refer to the boiler casing assembly instructions.
WIRING DIAGRAM
Refer to the diagram supplied with the specific switchboard.

5.6 DOOR
5.6.1 DOOR OPENING
The door is adjusted in the factory with standard opening to the left (s) and with hinges on the right (d).
CAUTION: it is dangerous to unscrew the ring nuts (8d) on the side of the hinges to avoid
causing the door to detach, with possible serious damage to people and property.
5.6.2 DOOR OPENING REVERSAL (TO THE RIGHT)
Only for models listed in the Technical Data table
Proceed as follows to reverse the opening direction of the door:
Door with ferrules perforated on both sides
1. Screw the left perforated ferrules (8s) so that the door seal gasket is pressed in the same way as the
right part. Bring the conical washers (10s) of the left tie-rods close to the mechanical tubes (9s) of the
door and tighten the nuts (7s) using a suitable wrench.
2. On the right opening side, loosen the nuts (7d) and free the conical washers (10d) from the mechanical
tubes (9d) of the door.
Door with wrench ferrules, hinge side
IMPORTANT NOTE: In models equipped with wrench-adjustable ferrules (8d), these must always be
mounted on the hinges to prevent the door from being accidentally opened through the lever (12).
In this case, proceed as follows:
3. Proceed as indicated in point 1.
4. Cross-change the wrench ferrule of a hinge (8d) with the opposite perforated ferrule (8s), after loosening
the locking nuts on the tie rods and freeing the conical washers.
5. On the left hinge side, fasten the conical washer (9s) onto the door using the nut (10s).
6. Proceed with the other two ferrules following the procedure described in points 4 and 5.
CAUTION: When cross-changing ferrules, always make sure that the other two ferrules
are fastened, so that they hold the door.
7. Check the correct adjustment of the tie-rods and hinges ensuring that, during closure, the seal gasket is
evenly pressed in the centre on the whole circumference (see figure).
If necessary, adjust as described in the next par.

18
5.6.3 DOOR ADJUSTMENT (OPENING ON THE RIGHT)
Vertical adjustment
1. With the door ajar, loosen the counter-nuts (5s) of the hinge units.
2. Act on the adjustment nuts (4s) to lift or lower the door by centring the gasket on the stop plate (see fig-
ure), then block the counter-nuts (5s).
3. Close the door and centre the tie-rod (1d) on the mechanical tube (9d), proceeding as in point 2.
Horizontal adjustment
Close the door using the lever and check that there is equal distance on both sides, between the stop plate
and the band.
Otherwise, proceed as follows:
1. With the door ajar, loosen the locking nuts (7s) of the hinge units.
2. Act on the ferrule (8s) to adjust the distance depth-wise.
3. Screw the nuts (7s) and block the conical washers on the mechanical tubes.
Check the proper adjustment in depth ensuring that the door, manually pushed up to the stop plate, naturally
returns remaining ajar. This is to ensure the hinge side fume seal.

5.7 BURNER CONNECTION
Before installation you are advised to thoroughly clean the inside of all the fuel supply system pipes in order
to remove any foreign matter that could affect correct operation of the boiler. See technical specification ta-
bles and check the max pressure value inside the furnace. The value found on the table may also increase
by 20% if heavy oil is used instead of gas or light oil; furthermore the following checks should also be carried
out:
a) Check the internal and external seal of the fuel supply system;
b) Regulate the fuel flow according to the power required by the boiler;
c) Check that the boiler is fired by the correct type of fuel;
d) Check that the fuel supply pressure is within the values specified on the burner rating plate;
e) Check that the fuel supply system is sized for the maximum flow rate necessary for the boiler and that it
is provided with all control and safety devices provided for by the regulations referred to above;
In particular, when using gas:
f) Check that the supply pipe and the gas ramp comply with the regulations in force;
g) Check that all the gas connections are sealed;
h) Check that the boiler room vents are of sufficient size to ensure the air flow dictated by the regulations
referred to above and that they are in any case sufficient to obtain perfect combustion.
i) Check that the gas pipes are not used as earth connections for electrical appliances.
If the boiler is not going to be used for some time, close the fuel supply cock or cocks.
IMPORTANT: check that the gap between the burner draught tube and the mounting plate are prop-
erly filled with thermoinsulating material.
The thermoinsulating strip provided with the boiler must be wrapped around the mouthpiece for at least an
entire circumference of the flame radiation to protect the flange of the burner. Not that the ceramic insulation
is necessary to fill the gap until the insulation inside surface of the door.
