MAINTENANCE
The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising
the efficient operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked
by a qualified chimney sweep at least once a year. Once maintenance has been performed, request a written declaration that the system
is safe.
Failure to clean the system jeopardises safety.
CHIMNEY CAP
The chimney cap is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney cap (A), see Figure
7.
The area of the openings for smoke
extraction must be at least double the
cross-section of the smoke duct/flue
system, and arranged so that smoke
extraction is ensured even in strong
wind. The chimney must prevent rain,
snow or animals from entering the
chimney. The height of outflow into
the atmosphere must be beyond the
reflux area due to the shape of the
roof or any obstacles near the outlet
(see Figures 2-3-4-5-6).
