TESTING
Check the burner has stopped by opening
the thermostats.
Check the burner's lockout during opera-
tion by interrupting the flame detector.
CONTROL BOX (see fig.11)
To remove the control box from the burner it is necessary to:
disconnect all the connectors, the 7-pin plug, the high voltage cables and
the earth wire (TB);
unscrew the bolt (A) and pull the control box in the direction of the arrow.
To install the control box it is necessary to:
screw the bolt (A) in at a torque of 1 - 1.2 Nm;
reconnect all the connectors previously disconnected.
NOTE: The burners have been type-approved for intermittent operation.
This means they must stop at least once every 24 hours in order to allow the
electrical control box to check its efficiency on start-up. The boiler limit ther-
mostat (TL) normally ensures the burner halts. If this does not happen a time
switch halting the burner at least once every 24 hours must be applied in se-
ries to limit thermostat (TL).

ATTENTION
Do not swap neutral and phase
over, follow the diagram shown
carefully and carry out a good
earth connection.
The section of the conductors must
be at least 1mm². (Unless requested
otherwise by local standards and
legislation).
The electrical wiring carried out by
the installer must be in compliance
with the rules in force in the country .
* (See
page 5). If any of the hydraulic sys-
tems feature the automatic shutoff
device (230V - max. 0.5A), it must
be connected to terminals N - T2 in
the 7-pin plug.
