DESCRIPTION
F 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 im-
portance that the room or building be properly ventilated so that enou-
gh fresh air is circulating at all times.
Hot air can be sent in the desired direction by moving the fins on
the air head (cfr. Fig 1).
Warning
To avoid overheating the combustion chamber the fins
must never be completely closed For this reason a
blocking bar prevents the complete closure of the fins.
F heaters can operate with burners of the ON-OFF type and
they are fuelled by heating oil.
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.
On models whose burners use heating oil there is a fuel tank (4)
attached to the front wall.
There are two safety devices which are activated in case of serious
malfunction. The Burner Control Device, which is mounted on the bur-
ner and has a restart button, automatically stops the burner if the flame
goes out, while the Overheat Thermostat, L, of the manual restart type,
is activated if the temperature of the combustion chamber rises above
the set maximum limit.
If any of these safety devices are activated you should check care-
fully what the problem actually is before pressing the restart button
and starting the heater off again (cfr. Observed faults, causes and re-
medies).

GENERAL ADVICE

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.
• The heater must be near a chimney or chimney flue and a suita-
ble 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 there 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 quali-
fied 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 room thermostat (2), the fan thermostat
and the overheat thermostat with manual restart have already been
connected.
Warning
The mains supply to the heater must be earthed and ha-
ve 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:
• Plug in the power cord having read the adhesive label which de-
tails electricity supply characteristics.
• The burner must be connected to the fuel supply using the two
flexible tubes mounted on the heater and interposing the oil filter (cfr.
Burner Instruction Manual).
• Connect the burner to the electricity supply with the burner plug .
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 (cfr. Technical Specifications). When the heater is
first turned on you must check that the fan does not use more current
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 with each unit 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 circum-
stances you must ensure that:
• The fan motor does not absorb more current than the maximum
permitted limit.
• The volume of air flow corresponds to the recommended level.
DRAFT
Efficient combustion and trouble-free working of the burner de-
pend on efficient flue draft. The unit must be connected to the chimney
flue in accordance with current legal regulations and in line with the
following guidelines:
• The tube which carries the smoke should cover as short a distan-
ce as possible and should slant upwards.
• There should be no sharp bends in the tubes and the diameter of
the tubes must never be reduced.
• Every heater must have its own chimney.
• Flue draft must at least correspond to the minimum compulsory
level in the Technical Specifications.
ANALYSIS OF COMBUSTION WASTE PRODUCTS
The probes which check the composition of combustion waste
products and smoke temperature must be positioned as indicated in
Fig.2.
When these tests have been completed the hole which was drilled
for the probe must be sealed with a material which is resistant to high
temperatures and which ensures that the tube remains airtight.
