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 sourc-
es to cool down completely.

After carrying out maintenance, cleaning or check-
