DESCRIPTION
SP space heaters have been designed for use in small to medium-
sized rooms and buildings where a fixed heating system is required.
Heat is produced by combustion and the heat from the smoke is
transmitted to the fresh air through the metal walls of the combustion
chamber and the heat exchanger. The combustion chamber is of the ty-
pe where smoke circulates twice.
The air and smoke pass through separated ducts, both of which
are welded and sealed. When, after combustion, the waste gases have
cooled, they are expelled through a duct which must be connected to a
chimney or chimney flue. The chimney or chimney flue must be big
enough to guarantee that the smoke is expelled efficiently.
The air which is used in combustion is aspirated directly from the
room or building which is being heated. It is therefore of utmost impor-
tance that the room or building be properly ventilated so that enough
fresh air is circulating at all times.
The air head has four lateral openings and adjustable fins which
sends the hot air in the desird direction (Fig.2).
Warning
During use, two of the four sides must be left open so as
to avoid overheating the combustion chamber.For this
reason the fins in the front which are on the same side of
the heater as the burner can never be completely closed
as they are blocked by a bar.
SP space heaters can operate with burners that are fuelled by hea-
ting oil, methane (G20) or L.P.G. (butane G30 and propane G31) of the
ON-OFF type.
Warning
Only the burners which are chosen and supplied by the
manufacturer can be used. If another type of burner is
used the heater no longer complies with CE regulations.
There are three safety devices which are activated in case of serious
malfunction. The Burner Control Device, which is mounted on the burn-
er and has a restart button, automatically stops the burner if the flame
goes out. The Overheat Thermostat, L, of the manual restart type, is ac-
tivated if the temperature of the combustion chamber rises above the
set maximum limit; the warning light (8) lights up and the heater stops
working. The Thermal Relay, RM, is activated if the fan motor starts to
use more electrical current than the maximum permitted limit; the
warning light (9) lights up and the heater stops working.
If any of these safety devices are activated you should check careful-
ly what the problem actually is before pressing the restart button and
starting the heater off again ("OBSERVED FAULTS, CAUSES AND
REMEDIES").

GENERAL ADVICES

The space heater must be installed, set up and used in accordance
with existing laws.
Here are a few general guidelines which should be followed:
• follow the instructions in this booklet very carefully;
• don't install the heater in places where there may be a risk of fire
or explosion;
• inflammable material should be kept at a safe distance from the
heater (Minimum 3 meters);
• all fire prevention regulations must be adhered to;
• the room or building which is being heated must be sufficiently
ventilated so that the heater has enough air to function properly.
Fig. 2
• the heater must be near a chimney or chimney flue and a suitable
electric switchboard;
• don't let animals or children near the heater;
• after use make sure the disconnecting switch is off.
When using any type of space heater it is obligatory:
• not to exceed the maximum level of heat output of the furnace.
• to make sure that there is adequate air circulation and air supply
to the heater and that 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. If the-
re is insufficient air supply the combustion chamber overheats
and the overheat thermostat with manual restart is activated.
INSTALLATION
Warning
The following operations must be carried out by qualified
personnel only.
ELECTRICAL CONNECTIONS AND SETTINGS
Every space heater is supplied along with the safety and control
devices which are indispensable to the correct functioning of the unit.
The electric switchboard, the fan thermostat and the overheat thermo-
stat with manual restart have already been connected.
Warning
The mains supply to the heater must be earthed and have
a magneto-thermal switch with differential.
The power cord must be connected to a switch board
which has a disconnecting switch.
The following operations must now be carried out:
• connect to the electricity supply (~1,220V,50Hz) with a power
cord of the HO7RN-F type (section 1 mm
not supplied with the heater;
• must be connected to the unit's electric switchboard by means of
the cable fastener and connected to the terminals N, F and T
("WIRING DIAGRAM");
• must be connected directly to a mains switchboard which has a
disconnecting switch;
• must not be longer than 2 meters;
• the burner must be mounted and attached to the heather with ap-
propriate screws. The gaskets supplied with the burner should be
placed between the burner and the heater;
• the burner must be connected to the fuel supply (Burner Instruc-
tion Manual);
• connect the burner to the electricity supply with the burner plug (11);
• connect accessories such as the room thermostat or clock to the
unit's electric switchboard: electric wires must be connected by
means of the cable fastener (7) to the terminals (6) and (7).
Having completed all these operations check carefully that all elec-
trical connections correspond to the wiring diagram and check the set-
ting of thermostat F ("TECHNICAL SPECIFICATIONS"). When the heater
is first turned on you must check that the fan does not use more cur-
rent than the maximum permitted limit. Finally, to regulate the burner
follow the instructions in the Burner Instruction Manual.
CONNECTION TO HOT AIR DUCTS
The space heater provides heat by releasing and dispersing hot air.
An air head is supplied and it can be connected to new air ducts if the
user wishes to satisfy specific needs. In this case and in particular if the
diameter and length of the ducts have been changed or if the number of
bends has been modified, air output may vary. Consequently it is very
important to check and regulate air output when any modification is
made to air heads or air ducts. In all circumstances you must ensure
that:
• the fan motor does not use more current than the maximum per-
mitted limit;
• the volume of air flow corresponds to the recommended level.
