CONNECTION OF THE BURNER
For the oil version is not necessary to do some operation on the
burner since it is already connected to the electric system, both to the
tank and it is regulated according to the indications of the builder.
For the gas version, on the contrary, the burner has to be assem-
bled on the space heater, connected to the fuel feeding line and
through the special taking to the electric panel and finally has to be
regulated following the instructions on the burner manual unanimously
to the technical data pointed for the space heater.
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
The evacuation smoke flues have to be in steel and conforming to
the norm EN 1443.
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 dis-
tance 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;
• the chimney flue has to have a length of 1 meter.
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.3, installing a rectilinear duct provided of hole with plug for collect-
ing smokes.
CONNECTION TO FUEL SUPPLY AND CHANGING FROM ONE TYPE OF
GAS TO ANOTHER
To connect the burner to the fuel supply, follow the instructions in
the Burner Instruction Manual.
The burner can use both methane gas and L.P.G. This heater has
been predisposed to use methane gas, G20. To change from methane
gas to L.P.G. or vice versa consult the Burner Instruction Manual
which accompanies this manual. With the Burner Instruction Manual
there is an envelope, which contains a spare choke and an adhesive la-
bel that indicates the type of gas that the burner should use.
INSTRUCTIONS FOR USE
SWITCHING ON
• Set the control knob (2) in position "0".
• Turn on the disconnecting switch on the electric switchboard.
• If the unit is operated manually turn the control knob to
burner starts up, the combustion chamber heats up and then the
fan starts.
• If the unit operates automatically set the room thermostat at the
desired level and turn the control knob (2) to
now start and stop automatically.

• If the heater doesn't start after you have completed the above
operations consult the Troubleshooting section of this manual.
TURNING OFF
In manual operation turn control knob (2) to "0" or turn off control
in automatic operation.
The burner stops while the fan turns itself on and off until the
combustion chamber has completely cooled down.
Warning
Never stop the heater by simply turning off the discon-
necting switch on the electric switchboard. The electri-
cal supply must only be disconnected when the fan has
come to a complete stop.
VENTILATION
When the control knob is turned to the symbol
ates in continuous fan mode.
MAINTENANCE
Warning
The following operations must be carried out by quali-
fied personnel only.
Finished all operation of maintenance, you have to restart the ma-
chine, verifying that every function is insured.
Warning
Before carrying out any maintenance operation the
heater must be disconnected from the mains. Therefore:
• Stop the machine as instructed above
• Turn off the disconnecting switch on the electric
switchboard
• Wait until the heater has cooled
Cleaning the heat exchanger and the combustion chamber.
For the heater to operate efficiently the heat exchanger and com-
bustion chamber must be cleaned after a period of prolonged use and
more frequently if too much soot builds up. Soot builds up when there
is not enough chimney draft, when the fuel is of very poor quality,
when the burner is regulated incorrrectly or when the heater is
switched on and off too frequently. If the heater starts vibrating when it
is turned on there is probably too much soot.
To reach the internal part of the heat exchanger and the combus-
tion chamber remove the burner (a) and the back panel (c) as well as
the exchanger inspection panel (e) and the baffle plates (d): Remove
soot and extraneous material with a vacuum cleaner or tube cleaner.

CLEANING THE FAN
Remove any dirt or extraneous material from the mesh of the aspi-
ration grill (f) and if necessary clean the propeller with an air-suction
tool.
