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).
