Before using the space heater, please read carefully all the instructions for use described below and follow the
indications scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused by improper use of
the equipment.
This instruction manual is an integral part of the equipment and must therefore be kept carefully and passed on
with the unit in the event of a change of ownership.
DESCRIPTION
The space heaters are designed for non-domestic heating of
medium or large ventilated rooms, which require a mobile and
portable heating system in compliance with standard EN
1596:2008, or for heating greenhouses, which require a fixed
heating system in compliance with standard EN 12669:2003.
The space heaters can be run on natural gas (G20, G25) or
L.P.G. (butane G30 and propane G31) according to different gas
supply pressures. Table l shows the useable gases and supply
pressures for each country in the European Union, plus the
corresponding category (which specifies gas type and supply
pressure), the setting of the gas valve unit, and the setting of the
diffusion ring (3).
Space heater is set up for one of the operating categories in
Tab. I: the adhesive label applied to the gas valve group (4)
indicates the operating category.
To convert to a different category and, therefore, to another
type of gas, follow the detailed instructions given in the section
"CHANGING TYPE OF GAS".
Space heaters are of the direct combustion type. The air is
heated by the thermal energy generated during combustion and
is then conveyed to the room to be heated with the products of
combustion: the room must in any case be suitably ventilated in
order to ensure adequate air circulation.
Various safety devices (electronic control unit, overheating
thermostat LI, air pressure switch, gas pressure switch) trip in the
event of serious malfunction.
The electronic burner control unit trips if the flame is irregular
or goes out. The overheating thermostat LI trips when the
temperature of the combustion chamber exceeds the safety limit.
The air pressure switch and gas pressure switch trip respectively
if the air flow is insufficient or if the gas supply pressure is too
low. In each of the cases described above, the space heater
stops working and the reset button light (8) comes on (except in
the event of low gas pressure). Working resumes automatically
only if the cause has been low gas pressure, when the missing
supply has been restored.
In other cases working operation can only be resumed by
pressing the reset button (8) or (4), as described in the
paragraph "FAULTS, CAUSES AND REMEDIES".
Nonetheless, the cause that triggered the safety device should
always be sought and remedied before restarting the heater (see
"FAULTS, CAUSES AND REMEDIES").
Space heaters can be completed with a series of accessories:
a) clock
timer
or
room
electromechanical device for automatic switching on and off
b) kit for remote control from a Personal Computer
c) kit for control from the remote panel (max distance 3 m),
useful for ceiling-mounted installations or in restricted
situations where access to the control panel is limited
d) anti-condensation kit, indispensable for installations under
very humid conditions (greenhouses, battery farming, etc.)
to solve the problem of ignition failure.
Warning
The reset button (8) may have different light types:
• light off: unit is working normally, flame is
regular.
• fast flashing: unit is running on starting cycle.
• slow flashing: unit is in stand-by status, waiting
for heating request.

GENERAL ADVICE
Installation, setting up and use of the hot air generator must be
effected in accordance with the applicable regulations and laws
relating to the use of such equipment.
The space heater can be installed suspended from the ceiling
by means of cables and/or chains of suitable size and length to
fix to the 4 suspension hooks.
Warning
Make sure that the cables and/or chains form a
maximum angle of 5° off vertical on the ceiling.
The minimum distance from surrounding walls, floor and/or
ceiling must be at least 1 m and the distance from the floor of at
least 500 mm.
The minimum proximity of objects, property, persons and/or
animals to be kept in front of the air distribution area must be at
least 1,5 m, having checked that they can support the maximum
temperature, which can be found by adding the room
temperature + ∆T @ 1.5 m (as shown on the identification label
affixed to the space heater itself).
Make sure that:
• The instructions in this manual are carefully followed;
• The generator is not installed in an area where there is a
high risk of fire or explosions;
• No flammable materials are stored in the vicinity of the
heater (the minimum distance must be at least 3 m)
• A check is made that there is no overheating of walls,
ceilings or floors made of flammable materials
• All precautions have been taken to prevent fires;
• Ventilation in the room where the heater is installed must be
guaranteed and sufficient for correct burner operation.
Specifically, limits concerning air quality in the room to be
heated must be complied with, as prescribed by national or
local standards and laws. In the absence of standards
and/or instructions, room ventilation may be determined
according to intended use:
• non-domestic heating of medium or large ventilated
rooms, as specified in EN 1596:2008;
• minimum room volume must be measured with
thermal power/volume ratio equal to 100 W/m
volume must NEVER be less than 100 m
• a minimum ventilation area of 25 cm
thermal power must be provided, the minimum being
2
250 cm
, divided equally between the upper and lower
part;
• heating of greenhouses, as specified in EN 12669:2003.
• The air suction and/or supply hoses are not blocked in any
way, there are not sheets or covers resting on the machine
or walls and bulky objects near the generator;
• The generator is placed near a power switchboard having
specifications that conform to those declared;
• The unit is placed in a fixed position;
• The heater is regularly monitored during operation and
checked before being started up;
• At the beginning of each working period, before plugging it
into the electrical power supply, a check is made that the
fan moves freely;
