IMPORTANT
Before using the space heater, carefully read all of the instructions and follow them 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 stored carefully and passed on with the unit
in the event of a change of ownership.
1. DESCRIPTION
Space heaters described in this manual, are designed for use in
medium to large-sized rooms and buildings where a fixed heating
system is required for indoor use
The air required for combustion is sucked directly by the burner (5)
installed on the heater, and is supplied from inside the room to be
heated. In this case, the room must be well ventilated to guarantee
sufficient exchange of air.
The flow of hot air is moved by the high-efficiency fan (3): air is heated
by the thermal energy generated during la combustion and heat from
the smoke is transmitted to the fresh air through the metal walls of
the sealed combustion chamber and the heat exchanger. After the
combustion products are cooled, they are conveyed to a discharge
duct and eliminated through a chimney or flue large enough to
guarantee their removal.
Air outlet (1), supplied as accessory and not included with heater, is
provided with adjustable louvres to allow proper direction of air flow
The space heaters can work with burners having ON-OFF work modes
and can run on diesel fuel.
Warning
Only burners approved by the manufacturer and listed in
the “TECHNICAL SPECIFICATION TABLE” can be used.
The heater’s certification and warranty will lapse if the
burner is replaced with a non-original model, even if it has
similar specifications.
All of the space heaters are fit with an electronic device that controls
the flame and with:
• safety devices (safety thermostat with manual reset, flame control)
that trip in case of serious malfunctions and cause a safety stop.
In this case the heater stops, button (d) lights with a steady red light
(Stop Light) and the heater can resume operation only after the
cause of the stop has been identified and eliminated;
• control devices (fan thermostat, burner thermostat) that trip in case
of minor operating faults or supply faults, causing temporary stop
of the space heater. In this case, the heater will restart
automatically when the required condition is restored.
The section “TROUBLESHOOTING” describes all possible operating
faults and their possible remedies.

3. GENERAL ADVICE
The space heater must be installed, adjusted, and used in conformity
to national and local laws and regulations for its operation.
General guidelines:
• Follow the instructions in this booklet very carefully;
• The heater is not installed in an area where there is a high risk of
fire or explosions;
• Keep inflammable material at a safe distance from the heater
(minimum 3 metres);
• Check that there is no overheating of walls, ceilings or floors made
of inflammable materials,
• All precautions have been taken to prevent fires;
• The room being heated must be sufficiently ventilated so that the
heater has enough air to function properly;
• The heater must be near a chimney or chimney flue and an
electrical panel conforming to declared specifications;
• Check the heater before switching it on and at regular intervals
during its use;
• After use, make sure the disconnecting switch is off.
When using any type of space heater it is obligatory:
• not to exceed the maximum heat output level of the furnace
(“TECHNICAL SPECIFICATION TABLE”);
• make sure that the air flow is not below the rated level; check that
there are no obstacles or obstructions to the air suction and/or
delivery ducts, such as sheets or covers on the equipment, walls or
large objects near the heater.
Warning
This unit may not be used by persons (including children)
with reduced physical, sensorial or mental capacities or
