DESCRIPTION
The air treatment unit essentially represents a thermal group that exchanges the combustion products of a
forced-air gas burner with an air flow generated by a group of highly efficient fans.
The air to be heated is sucked by the latter and when it touches the hot surfaces of the heat exchanger, the
air temperature rises; the air can be distributed both directly and through special ducts.
The characteristics of the centrifugal fan make the equipment suitable to be installed on plants needing the
distribution of hot air through ducts or, in general, when it is necessary to have static pressure.
This heating system makes it possible to remarkably reduce the plant costs and ensure savings in operating,
being particularly suitable for discontinuous and occasional use.
The special configuration of the counter-current flow heat exchanger optimises the heat exchange and
makes the equipment to work with condensate.
Besides, the equipment is realised in a way that it can operate with variable heating power and air flow, in
order to adapt to the real heating requirements of the environment.
In summer it is possible to operate the ventilating unit only.
GENERAL DESIGN AND FUNCTIONAL CHARACTERISTICS:
Heat exchanger:
It is made of a welded steel sheet, easy accessible for cleaning and maintenance. It is made up of:
•Combustion chamber made of AISI 430 STAINLESS STEEL, with a low thermal load, with
ovoidal shape and suitable volume.
•Patented, modular exchange elements of AISI 304 STAINLESS STEEL, wide surface, with
whirlpooling marks and counter-current position, in order to optimize the thermal exchange. The
exchange elements are inclined to facilitate the drainage of combustion product condensate.
•Exhaust manifold of AISI 304 STAINLESS STEEL, with shutters for inspection.
Supporting frame:
The supporting frame is made of press-folded, powder-painted and galvanised steel.
The mitre joints are made of strong and die-cast aluminium and are fully designed by the Manufacturer.
Closing panels:
The closing panels are made of coated galvanised steel or of pre-coated sheets; they are thermally insulated
with a mineral fibre mat, and are provided with galvanised counter-panel sheets. These panels can be
removed to perform the ordinary internal inspection.
Ventilation unit
The unit is made up of a centrifugal fan with backward blades and low noise emission and high efficiency;
they are powered by an electric motor connected by means of a belts and pulleys driven transmission
system, which provides this product with high reliability of the plant it is to be used with.
“LM” safety thermostat:
The air treatment unit is equipped with a safety thermostat whose sensors is placed on the air outlet. It
stops the burner if the air is anomalously overheated. It has to be manually reset, after removing the cause
that has caused its intervention.

HEAT EXCHANGER SCHEME
Axonometric image of the heat exchanger:
Combustion products
•create an inversion in the combustion chamber;
•are transferred into the first smoke collector and then flow into the first row of exchanging
elements;
•arrive to the second smoke collector and then flow into the second row of exchanging elements;
•are discharged from the equipment through the circular junction.
In order to keep the combustion products speed at an optimal level, the section of the smoke
passage has a decreasing gradient.
The smoke duct elements are slightly inclined to facilitate the condensate drain.
The two fluids (air \ combustion products) are in counter-current.
These are some of the design specifications that make this innovative heat exchanger
extremely efficient.

GENERAL INSTRUCTION TO MOVE AND TRANSPORT THE APPLIANCE
WARNING!
The appliance should be moved by adequately equipped persons and with tools suitable for the appliance
weight.
The machine should be extremely carefully transported and moved, so as to prevent damages to the
machine and dangers for those performing the operation.
While the machine is being transported or moved, do not stay near it.
The forks to be used should be at least as long as the machine width.
A lifting beam (not included in the shipment) must be employed, if belts and ropes are used in the handling,
in order to avoid damaging the equipment structure by the pressure of the latter.
If it is necessary to line up several machines, the stacking index (written on the packaging) should
compulsorily be complied with and the boxes should be lined up so as not create unstable stacks.
We suggest using protection gloves.

INSTALLATION AND SETTING INSTRUCTIONS
- 15 -
TRANSPORT LOCKS
To prevent damage to the appliance during transportation, some red mechanical locks can be used, limiting
the movement of some internal elements. Their identification and the instructions to remove them are
specified on a self-sticking tag placed on the appliance.
THE LOCKS MUST BE REMOVED BEFORE THE FIRST COMMISSIONING.
POSITION
The installation setting should be defined by the plant designer or by a competent person and it should take
into account the technical needs as well as the relevant laws and regulations in force; specific authorizations
are usually required. (e.g.: regulations concerning city planning, architecture, fire prevention, environmental
pollution, noise level, etc.)
Therefore, we suggest requesting and obtaining the relevant authorizations before installing the machine.
If the appliance is to be installed in sport facilities, specific skills and experience are required
since the following requirements should be met: highest quietness, limited air stratification, air
distribution uniformity, without generating unpleasant currents. If you have any doubt, pleas
ask the Manufacturer to receive the appropriate technical support.
To be properly installed, the air treatment unit should:
•be laid on all the lower frame rang;
•be placed on a flat, non wet surface, capable of bearing its weight;
•be placed on a surface that is high and solid enough to avoid transmission of vibrations to the premises
underneath;
•be placed in compliance with the specified distances so that air can properly flow and that ordinary
cleaning and maintenance operations can be performed;
•be placed in compliance with the specified distance from inflammable substances;
•be easily connected to the gas grid;
•be placed close to a power socket;
•be close to the duct which discharges the combustion products out of the premises;
•be such that all the maintenance and control operations can be easily performed;
•be fitted with the ventilation openings required by the relevant regulations.
We suggest not installing the machine :
•in places with aggressive atmosphere;
•in narrow places where the heater noise level can be magnified by reverberation and resonance;
•in corners where leaves can deposit or any other materials might obstruct the air opening, thus
decreasing the heater efficiency;
•in places with an higher pressure;
•in places with a lower pressure;

INSTALLATION AND SETTING INSTRUCTIONS
- 16 -
CLEREANCE AREA
The machine shall be easily and safely reached without needing special equipment (ladders -
movable platforms -etc.). Around the machine, minimum distances shall be complied with so that the
control and/or maintenance operations can be performed and that no obstacles block the air flow.
WARNING!
Any Laws or specific regulations requirements (e.g. fire prevention) shall be complied with. Consult the plant
designer.
FUEL CONNECTION
The machine should be connected to the gas (GPL or butane) network by qualified personnel in compliance
with installation instruction.
For appliances fuelled by gas, we recommend installing a leakage detector controlling an electric valve that
stops the gas supply if any leakage is detected.

The smoke duct and chimney flue connection must be made in conformity with the Standards and
Legislations in force; they are to be made with rigid metal ducts, resistant to combustion mechanical,
thermal, and chemical stress
The smoke ducts connecting the equipment to the chimney flues must be easy to
dismantle; this is an indispensable condition to allow the checking and internal cleaning
of the heat exchanger.

WARNING!
All stove components must be CEE certified.
There must be a condensate drain at the lowest part of the smoke duct (see diagram),
in order to avoid condensate backflow from the chimney flue to the air treatment unit.
The total weight of the smoke exhaust pipe must not weigh on the appliance.
It is mandatory to install a device (ex. level switch), which stops burner in case of
accidental clog of the condensate drain (see also the “condensate drain” paragraph).
Moreover, we recommend:
•avoid or however limit horizontal sections which in all cases should have a rising
gradient;
•use ducts having a smooth internal surface, made of material resistant to the flue gas
thermal and chemical stresses, with equal or higher diameter than the one of the
connection on the appliance;
•avoid tight curves and section reduction;
•have a cockpit for the combustion products sampling and analysis;
•adequately connect the smoke exhaust duct;
•have a suitable terminal to avoid rainwater infiltration into the equipment, and
simultaneously, to avoid high loss of load.

INSTALLATION AND SETTING INSTRUCTIONS
- 18 -
The chimney flue must guarantee minimum depression, as provided for by Technical Standards in force,
taking into consideration that the pressure is “zero” at the joining point with the smoke duct.
Non-insulated exhaust ducts are a source of potential hazard.
Inadequate or wrongly sized chimney flues or smoke ducts may amplify the combustion noise and negatively
influence the combustion parameters.
The joints must be sealed with materials resistant to thermal and chemical stress caused by combustion
products.
Crossings through walls and/or roofs, if any, must be performed up to standard, in order to avoid hazards of
fire and/or water infiltration.
CONDENSATE DRAIN CONNECTION
The condensate drain system should comply with the relevant European, National and Local Standards, and
the need for a neutralisation treatment should be checked.
We provide the following instructions, for information purposes:
•the condensate drain system should be dimensioned and made in a such a way that liquids can flow out,
without leaking;
•all condensate drain unions should be independently connected, and they should not be combined in one
duct;
•smokes must be prevented from being discharged through the condensate drain system; therefore a
syphon should compulsorily be installed.
•Condensate that may accumulate in the chimney flue, must never be permitted to backflow into the
equipment. A specific condensate drain must be created;
•The system should have a proper gradient. Pipes should not be installed at the same level of the machine
nor in counter-inclination.
•In case of connection to the domestic sewage net, a suitable trap or equivalent device is to be used in
order to prevent any backflow from the sewage net;
•The system must be made in a way as to prevent the freezing of the liquids it contains, in all
expected operating conditions;
•The system is to be provided with a device that stops the burner in case of accidental clog of the
condensate drain system, in order to avoid hazard situations or unhealthy combustion;
