ELECTRICAL CONNECTIONS
• It is advisable to make all connections with flexible electric wire.
• The power lines must be distanced from the hot parts.
• The burner installation is allowed only in environments with
pollution degree 2 as indicated in annex M of the EN 60335-
1:2008-07 regulation.
• Make sure that the power line to which the unit will be connected,
has frequency and voltage values suitable for the burner.
• The three-phase or single-phase power supply line must have
a switch with fuses. The standards also require a switch on the
burner's power line located outside the boiler room where it can
be accessed easily.
• The main line, the relevant switch with fuses and the possible
limiter must be suitable to support the maximum current
absorbed by the burner.
• For the mains supply connection is required an omnipolar switch
with a contact opening gap equal or above 3 mm in accordance
with current safety regulations.
• Refer to the wiring diagram for electrical connections (line and
thermostats).
• Remove the external insulating seal of the supply pipe necessary
for the connection, preventing the cable to touch metal parts.
To carry out the connection of the burner to the power supply line
proceed as follows:
• Insert the two 7- and 4-pole connectors into the appropriate
sockets located below the electrical switchboard support base.
• To reach the electrical components, loosen the two screws (6),
gently pull back the cover to detach them from the electrical
panel base, then lift it.
• Close the cover again making sure to position the two hooks (3)
correctly in their respective housings.
CAUTION / WARNINGS
Only professionally qualified personnel may open the
burner electrical switchboard.
• In case of phase-phase 230V electrical grids, if these latter are
unbalanced, the voltage between flame detection electrode and
ground can not be enough to ensure burner correct operation.
The problem is solved by using a type AR1 insulating transformer
cod.0005020028 connected as shown in the following diagram.
The electric motor is equipped with an automatic reset thermal
cut-out that causes it to stop when overheating.
CAUTION / WARNINGS
If it stops please make sure that the motor is in good
conditions and verify the causes of its overheating.
