4.5 Cleaning the flue pipes
A reduction in the heat output can almost always be attributed to obstruction of the flue. The leakage of fumes
from the cooker can also indicate a blocked flue.
The cooker flue must be cleaned at regular intervals. The quantity of soot produced and the frequency of
cleaning will depend largely on the type of fuel burnt and how the cooker is used (i.e. with low or high output).
To clean the flue pipes, proceed as follows:
-
clean only when the cooker is off;
-
close all the openings which are not to be cleaned;
-
remove the flue pipes and clean them outdoors;
-
clean and remove with a vacuum cleaner all deposits inside the cooker, after removing the hotplate rings
and their support;
-
all residue on the grate or in the ash pan must be removed
Take care when refitting the pipes not to damage enamelled or painted parts and the seals .
Dispose of cleaning waste in accordance with the current local regulations.
