ATTENTION:
®
Do not swap neutral and phase over, follow the diagram shown care-
fully 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
Connect the 2nd stage thermostat (TR) to terminals T6 - T8 and remove
the bridge.
TESTING
®
Check the burner has stopped by opening the thermostats.
®
Check that the burner is blocked by opening the connector (CN1) inserted
in the probe red wire and located outside the control box.
CONTROL BOX, (see fig. 8)
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, fig. 8) 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.
NOTES
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 thermostat (TL) normally en-
sures the burner halts. If this does not happen a time switch halting the burner at
least once every 24 hours must be applied in series to limit thermostat (TL).
