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.
DESCRIPTION
Space heaters
are designed for non-domestic heating of medium
and large ventilated premises, for which a mobile heating system is
required in accordance with EN 1596:2008.
Warning
DO NOT USE TO HEAT HABITABLE AREAS OF
RESIDENTIAL BUILDINGS.
REFER TO NATIONAL REGULATIONS FOR USE IN
PUBLIC BUILDINGS.
Space heaters can be run on propane gas (G31) or on L.P.G.
(butane G30 and propane G31) according to the different gas
categories indicated on Tab. I and shown on the heater identification
plate.
Space heaters are direct-combustion and forced convention units.
Air is heated by the thermal energy generated during combustion and
is then conveyed to the room to be heated along with the combustion
products: the room MUST be suitably ventilated to ensure adequate
air circulation.
Various safety devices trip in the event of serious malfunction:
• the thermocouple and the thermal gas valve (M and M DV
models) trip to close the gas flow if the flame is irregular or if it
goes out;
• the electronic burner control unit trips if the flame is irregular or
goes out (type A models): the reset button (8) lights up with a
steady red light;
• the overheating thermostat LI trips when the temperature of the
combustion chamber exceeds the safety limit;
In each of the cases described above, the space heater stops
working in lock-out condition.
Warning
You must always identify the cause of the “block” and
eliminate it before restarting the heater (see:
“TROUBLESHOOTING”).
Type A models can restart only if reset button “8” is
pressed (red lamp is off).
Warning
For A models, 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.
• steady light: lock-out status.
GENERAL ADVICE
The heater must be installed, set up and used in accordance with
the applicable regulations and laws relating to the use of such
equipment.
Minimum distance from surrounding walls and/or ceiling: 2 m.
Warning
Do not use the heater on floors made with flammable
materials.
Warning
Use in basements or below ground level is hazardous
because of gas stagnation.
Make sure that:
• The instructions in this manual are carefully followed;
• The heater 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
(minimum distance: 3 m);
• There is no overheating of walls, or ceilings made of flammable
materials,
• All precautions have been taken to prevent fires;
• The premises in which the heater is installed are sufficiently
ventilated for the burner requirements; in particular, limits
regarding air quality in the room to be heated must conform to
applicable national or local laws or, in the absence of any
standards and/or indications, to the provisions of EN 1596:2008:
• minimum room volume must be measured with thermal
power/volume ratio equal to 100 W/m
3
. Room volume must
NEVER be less than 100 m
3
;
• a minimum ventilation area of 25 cm
2
per kW of thermal
power must be provided, the minimum being 250 cm
2
, divided
equally between the upper and lower part;
• Nothing is obstructing the aspiration and expulsion of air;
movement of air may be obstructed in various ways including
placing covers or other objects on the heater or positioning the
heater too near a wall or other large object;
• The generator is placed near a power switchboard having
specifications that conform to those declared;
• The unit is placed in a stable position;
• The hot air jet is directed towards the cylinder.
• The heater is regularly monitored during operation and checked
before being started;
• At the beginning of each work period, a check is made that the
fan moves freely before plugging the heater into the electrical
power supply;
• At the end of each work period, the mains switch is disengaged
and supply power cord removed, main gas stopcock is closed
and gas tube disengaged and sealed.
Warning
This unit may not be used by persons (including
children) with reduced physical, sensorial or mental
capacities or with limited experience and familiarity
unless they are under supervision or instructed on
how to use the unit by the person responsible for its
safety.
INSTALLATION INSTRUCTIONS
Warning
All of the operations described in this section must be
performed by professional and skilled personnel only.
POWER CONNECTIONS
Warning
The power line must be earthed and fitted with a
residual current circuit breaker.
The power cable must be connected to a panel fitted
with a cut-out.
Before plugging the heater into the electrical power supply, check
that the power supply specifications are the same as those stated on
the identification plate.
A models may be connected to a room thermostat or other
accessories (such as the timer) by connecting to the thermostat plug
(10).
