MAIN SAFETY RULES
Bear in mind that if you use products powered trough electric power, gas, etc., you should comply with some basic
rules, such as:
Children and unassisted disabled people must not use the hot air generator.
Do not operate electrical devices such as switches, electrical appliances, etc. if you can smell fuel. In this case:
• air the room by opening doors and windows;
• close the fuel control device;
• promptly request the intervention of the Technical Assistance Service or of skilled personnel.
Do not touch the unit barefoot or when parts of the body are wet or damp.
Do not clean or perform maintenance before disconnecting the unit from the electrical power supply by turning the
main switch of the system to "OFF", and shutting-off the fuel.
Do not modify the safety or adjustment systems without authorization and the instructions of the manufacturer of
the unit.
Do not pull, disconnect and twist the electrical cables coming from the unit, even if it is disconnected from the
electrical power supply.
Do not open the access doors to the inside of the unit, without turning the main switch of the unit to "OFF".
Do not dispose of, abandon or leave within the reach of children, the packaging materials (cardboard, staples, plastic
bags, etc.), as they may be potentially dangerous.
Do not install the unit near flammable material, or in rooms with an aggressive atmosphere.
No object should be placed over the machine nor inserted through its case grill or through the combustion product
exhaust ducts.
The exhaust duct should not be touched, since during normal operations it might reach high temperatures, being
therefore dangerous to be touched.
Do not use adaptors, power strips and extension cables for the electrical connection of the unit.
Do not install the unit beyond the limits of use and operation shown in the instruction manual.
The warm air heater shall not be directly installed in small areas lacking proper ventilation, since the air intake might
cause a remarkable depression within the room, causing serious problems.
The burner should not be installed outside and should not be directly exposed to bad weather
DISPOSAL INSTRUCTIONS
Disposing of the appliance must be performed by an authorised company and in compliance
with the applicable laws.
Before taking waste to Authorised Collection Centres, dismantle and separate the various
materials that compose it which in summary are:
•ferrous materials;
•aluminium;
•electrical wiring;
•gaskets;
•insulating materials;
•plastic materials;
•electronic cards.

DESCRIPTION OF THE UNIT
The warm air generator is basically a thermal unit that exchanges the products resulting from the combustion
of a forced draught burner for the air flow produced by a high-performing ventilation unit.
The air to be heated is sucked by the ventilation unit and, when it laps the hot surface of the heat exchanger,
it is heated - increasing its temperature; then it can be distributed both directly and through proper channels.
Thanks to its features, the centrifugal fan can be installed in plants requiring the distribution of the heated
through channels or, in general, where static pressure is needed.
Through this heating system, the plant costs can be remarkably reduced and a reliable operating economy
can be reached; therefore, it is particularly fit for those cases where it will be used occasionally and
discontinuously.
The specific hot air generator has been designed to be combined with a gas burner with variable thermal
power (two-stage or modulating); in reduced thermal power operation, the flue gas temperature drops below
the dew point, the condensation phenomenon starts, and recovery of the "latent energy" contained in the
water vapour that normally occurs in the chemical process of combustion takes place.
The high-quality materials used to manufacture the heat exchanger ensure safe and long-lasting operation
even under with condensation of the combustion products, which is discharged to the outside through a
dedicated connection.
Combination with a burner with variable thermal power allows the continuous and linear control of the thermal
power of the appliance in relation to the immediate needs of the user, maximising operating economy.
In summer, it is also possible to use only the fan unit.
CONSTRUCTION FEATURES AND GENERAL FUNCTIONS:
Heat Exchanger:
It is made of welded stainless steel, it can be easily inspected for ordinarily cleaning and maintenance
operations and it comprises the following elements:
•Combustion chamber made ofAISI 430 stainless steel, with low thermal load, cylindrical or egg-
shaped and of the appropriate size.
•Exchange elements in stainless steel AISI 304 stainless steel with a large surface, with turbulent
impressions and equipped with special reticular turbulators.
•Smoke manifold in stainless steel AISI 304 stainless steel, equipped with inspection door and
condensate discharge connection.
External casing:
The case is made up of removable boards of pre-painted sheets and/or powder-painted and it includes also:
•Anti-radiant thermal insulation of the surfaces exposed to the heater irradiation.
•Outlet flange to connect the warm air distribution circuit.
•Intake flanged plenum to connect the treated air intake circuit.
The 38 type devices include a press-formed galvanised steel profile, which has been powder-painted with
corner-joints made of strong and special pressure-cast aluminium profiles, completely designed by the
Manufacturer.

- 7 -
Fan assembly:
It is made up by one or more low noise emission and high-performing centrifugal fans, powered by an electric
engine connected to a pulley and belt driving system. If possible, the engine is equipped with a variable-pace
pulley, which ensures that the machine will easily adapt to the destination plant.
Control and safety thermostat:
The machines are equipped with thermostats; their sensor shall be placed on the air outlet (prepared and
electrically connected in the manufacturing plant), with the following functions:
•"FAN" function (FAN thermostat –calibration: +25/+35°C), it activates the fans max. 60 seconds
after the burner has started and it stops them approx. 4 minutes after it has stopped. Thus, it prevents
unpleasantly cold air from being released in the room when the machine is activated and the thermal
energy accumulated by the heat exchanger can be exhausted, by completely using it before the
machine stops.
•“SAFETY” function (TR safety thermostat - pre-set calibration: +80°C ). It is installed on the 3÷8
types. It stops the burner if the air is anomalously overheated. It is automatically restored. It shall be
correctly calibrated when it is used for the first time.
•"LIMIT" function (LM Thermostat - sealed calibration: +100°C): it stops the burner if the air is
anomalously overheated. It shall be manually restarted.
Smoke discharge inlet
The machine is fitted with a round inlet where a metal pipe should be safely inserted and fixed, in order to
discharge the combustion products. The flue to be used must be in accordance with and certified
standard .
Condensate drainage connector
Since the combustion products are expected to function with an output of condensation, the device is equipped
with a threaded connection for the discharge of condensation; it must be connected according to current
standards in force.
