• Connect accessories such as the room thermostat or clock to the
unit’s electric switchboard: electric wire must be connected by
means of the cable fastener (8)
Table 1
Table 2
Having completed all these operations check carefully that all
electrical connections correspond to the wiring diagram. 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 but it can be replaced by other
types of head with two or four openings which allow for flexible tubes in
heat distribution. The screws which hold the original outlet in place
should be removed and the new outlet should be screwed on in placeof
the old.
The air head can also be replaced by one of the “plenum” type. In this
case the front panel is removed and replaced by the “plenum”.
The new head with the exception of the “plenum”, may 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 absorb more current than the maximum
permitted limit;
• The volume of air flow corresponds to the recommended level.
If the heater is equipped with centrifugal fan and if the volume of hot
air differs from preset values proceed as follows (Fig.1):
1) Remove the aspiration grill which is on fan motor side of the unit;
2) Remove the screws (2) from the motor slide.
3) Remove the belt (1);
4) Loosen the bolts (3);
5) Turn the pulley clockwise and anti-clockwise in order to increase or
reduce the volume of air;
6) Tighten the bolts (3);
7) Put back the aspirations grill;
8) Repeat operations (1) - (7) until the correct volume of air flow has
been achieved.

DRAFT
The evacuation smoke flues have to be in steel and of conforming to
the norm EN 1443.
Efficient combustion and trouble-free working of the burner depend
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 distance
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.

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. The gas used to
predispose the heater at factory has been declared on data plates
applied on the box and on the heater itself (methane, G20, or L.P.G.,
G30, G31).
To change from methane gas to L.P.G. or vice-versa you must:
• adapt the burner following the instructions manual;
• repeat regulation of combustion while composition of combustion
waste products are checked.
• correct data plate on the heater writing which type of gas must be
used.
REGULATION OF COMBUSTION - I
st
OPERATION
After having checked the hermetic seal and of combustion waste
products line, heater may be operated for the first time.
To perform regulation of combustion correctly, combustion waste
products must be analyzed using appropriate instruments: values
recommended by actual standards must be reached.
Adjustments to be carried out are described in the Burner Instruction
Manual; final values of CO
2
shall be correspondant to excess air factor
of 1,2 (12,5% for gas-oil, 9,7% for G20, 9,6% for G25, 11,7% for G30
and 11,7% for G31) while CO level shall be less than 75 ppm.
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 .The
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 : the heater will 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.
