GENERAL INFORMATION AND PRECAUTIONS
This machine is suitable for the following uses:
a) Direct heating of the blown air through its own fan unit.
The heat exchange occurs by contact between the external walls of the combustion chamber / heat exchanger and the air
that passes through it.
b) Ventilation only.
In mode (a), the machine must be equipped with a burner, connected to the electric power supply line, to the gas pipe and to
a suitable system for discharging the products of combustion and condensate.
In mode (b) it is sufficient to connect the machine to the power supply line.
This machine must be used for heating the room air.
Attention is drawn to the fact that the machine is not suitable for use for other purposes; and in particular it is
not suitable for use in normal operation at average air outlet temperatures above 80 ° C.
The manufacturer is solely responsible for the functional characteristics of the machine
if it is used in the manner and within the limits described in this manual.
Liability and Warranty
The manufacturer guarantees its new products from the date of installation in accordance with current regulations and / or in
accordance with the sales contract.
Verify, upon initial start-up, that the machine is intact and complete.
Failure to comply with what is described in this manual, operational negligence, incorrect installation and the execution of
unauthorized modifications, cause the manufacturer to void the machine warranty.
In particular, the warranty and liability rights expire in the event of damage to persons and / or things, if the damage itself is
attributable to one or more of the following causes:
-incorrect installation, commissioning, use and maintenance of the machine;
-improper, erroneous and unreasonable use of the machine;
-intervention of unskilled personnel;
-execution of unauthorized modifications to the machine;
-use of the machine with defective safety devices, incorrectly applied and / or not working;
-installation of additional components not tested together with the machine;
-supplying the burner with unsuitable fuels;
-defects in the fuel supply system;
-use of the machine even following the occurrence of an error and / or an anomaly;
-repairs and / or overhauls performed incorrectly;
-modification of the combustion chamber by introducing inserts that prevent the regular development of the
constructively established flame;
-insufficient and inappropriate supervision and care of the machine components most subject to wear;
-use of non-original components, whether they are spare parts, kits, accessories and optionals;
-causes of force majeure.
Furthermore, the manufacturer furthermore declines any and every responsibility for the failure to observe
the contents of this manual.
WARNING

Information on safety and prevention
The machine has been designed and built in compliance with the standards and directives in force, applying the known
technical safety rules and providing for all potential dangerous situations.
However, it is necessary to take into account that careless and clumsy use of the machine can cause situations of danger
of death for the user or third parties, as well as damage to the machine itself or to other assets.
Distraction, lightness and too much confidence are often the cause of injuries; as can fatigue and drowsiness.
The following should be taken into consideration:
-the machine must only be used for the use for which it was expressly intended.
-Any other use is to be considered improper and therefore dangerous.
In particular:
The type and pressure of the fuel, the voltage and frequency of the supply voltage, the minimum and maximum flow rates
at which the machine can be adjusted, the ambient temperature, must be within the values indicated in this manual.
-It is not allowed to modify the machine to alter its performance and intended use.
-The machine must be used in flawless technical safety conditions.
Any disturbances that could compromise safety must be eliminated promptly.
-It is not allowed to open or tamper with the machine components, except only the parts required for maintenance.
-Only the parts specified by the manufacturer can be replaced.
The manufacturer guarantees safety and proper functioning only if all machine components are intact and positioned
correctly.

CONSTRUCTION EXAMINATION AND SAFETY REQUIREMENTS
The warm air heater consists of an aluminium frame and an external panelling in pre-painted sheet metal: the panels are
internally insulated with a glass wool mat.
In the heating section we find a combustion chamber and a heat exchanger.
In this area, the insulating mat is protected against the danger of overheating by a galvanized sheet cover.
In the fan section, located in the lower part of the warm air heater, there are one or more double inlet centrifugal fans,
individually driven by a three-phase electric motor / s with belt drive / s.
The fan unit is protected by an anti-finger grid that prevents accidental contact with parts of the body and the entry of leaves
or external objects.
It is designed to prevent the entry of a ball with a diameter of 16 mm, with a force of 5N.
The grid can only be removed with the aid of a tool.
The combustion chamber, built in stainless steel for high temperatures, is fixed to the frame so that its thermal expansion
does not compromise its duration over time.
The heat exchanger made with stainless steel tubes is solidly welded to the combustion chamber.
Suitable openings on both sides allow easy access for inspection and maintenance.
On the front side of the warm air heater we find:
-a plate to fit the automatic forced draught gas / fuel oil burner
-an electric control board complete with
-switch
-HEATING / VENTILATION / BURNER STOP switch
-voltage indicator
-remote switch thermal intervention light (only in 3F models)
-Safety Limit intervention light;
a combination of 3 thermostats (TRITHERMOSTAT) ensure the following control and safety functions:
-FAN (TR): thermostat normally open for the automatic start and stop of the fan unit in
"HEATING" phase;
-LIMIT (TW): burner maximum thermostat, normally closed with automatic reset.
oAutomatically turns off the burner to prevent the air temperature at the warm air heater
outlet exceeding the safety limit;
-LIMIT2 (STB): burner safety thermostat, normally closed with manual reset and a positive security.
oAutomatically turns off the burner to prevent the air temperature at the warm air heater outlet from
exceeding the safety limit set by the reference standard.
Its calibration is imposed at 100°C by the manufacturer and must not be modified to avoid overheat of the
warm air heater;
(to reset the burner, read the instructions in the Chapter: TRI-THERMOSTAT).

8
Other essential safety requirements
Electrical equipment.
After the various assembly stages, all warm air heaters are subjected to the following electrical checks to verify compliance:
-visual check of the electrical circuit and tightening of the connections;
-continuity of the earth circuit;
-insulation resistance test;
-voltage test.
Temperatures.
The temperatures of the accessible areas for normal use of the warm air heater comply with the European reference standard.
Noise.
All the necessary measures have been taken to contain noise.
The values in dB (A) are shown in the tables Chapter: TECHNICAL DATA.
Reports.
The signals on the controls and on the alarm devices are made with graphic symbols according to the ISO7000 standard.
For an explanation of the symbols used, refer to the Chapter Explanation of Graphic Symbols on page. 4.
At the beginning of each heating season and, according to the deadlines set by law and regulations, the operator must have
the efficiency of all functional and safety parts of the machine checked by specialized personnel and have the combustion
checked.
The results of these interventions will be recorded in the "central booklet".
The air filter, if provided, must be kept clean frequently to keep it clean.
It must be removed from its frame, blown with compressed air (see MAINTENANCE chapter) and put back in its frame.
When the air intake grille is dirty, it must be cleaned with a brush or vacuum cleaner without however removing it.

1) Short side (Q) + long side (P) + short side (Q).
2) The final speed of the blown air is 0.15 m/sec, and the nozzle fins’ deflection is 0°.
If deflection = 30°, multiply the blown air value by 0.65.

1) Efficiency ASHRAE52/76 DUST WEIGHT: 87%
2) Pressure drop of a new filter.
CAUTION! For plant calculations, this pressure drop for rather
dirty (but not clogged) filters must be increased by at least 50%,
and must be subtracted from the useful pressure of the heater
(see chap. DATA SHEET)
