m 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, burner, the fan thermostat, overheat
safety thermostat and the overheat thermostat with manual restart
have already been connected.
m 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:
• Plug in the power cord having read the adhesive label which de-
tails electricity supply characteristics (Tab.1). Tab. 2 shows the
adhesive label on units which have three-phase supply.
• The burner must be connected to the fuel supply (Burner Instruc-
tion Manual).
• Connect the burner to the electricity supply with the burner plug.
• 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) to the terminals 6 and 7.
Having completed all these operations check carefully that all elec-
trical connections correspond to the wiring diagram. When the heat-
er 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 oth-
er 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 place of 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 connect-
ed 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.2):
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 from (1) to (7) until the correct volume of air
flow has been achieved.

DRAFT
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.
