Cleaning the impeller
Check that there is no dust inside the impeller as this could re-
duce the combustion performance. Perform maintenance ope-
rations while being careful not to damage the fan. Check that
the impeller is properly positioned inside the burner body.
Observe the following sequence:
– loosen the screws (1) and remove the air intake duct (2);
– clean the impeller (3) and the air duct using a paintbrush;
– if necessary, dismantle the impeller and mount it back on.
