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.10)
To remove the control box from the burner it is necessary to:
Fig. 10
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 thermostat (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 series to (TL).
