Maintenance

7.3

Opening the burner



Remove the tie-rods 1) and 4)(Fig. 36) of the head move-
ment and damper opening lever, loosening the nuts 2);



disconnect the socket 3) of the servomotor;



remove the screws 5).



At this point, it is possible to open the burner on the hinge.

7.4

Closing the burner

Refit following the steps described but in reverse order; refit all
burner components as they were originally assembled.

DANGER

Disconnect the electrical supply from the burner
by means of the main system switch.

DANGER

Close the fuel interception tap.

Wait for the components in contact with heat
sources to cool down completely.
