MAINTENANCE
The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft, thus compromising
the efficient operation of the product and, if large build-ups accumulate, they can catch fire. The flue and chimney must be cleaned and
checked by a qualified chimney sweep at least once a year. Once the maintenance has been performed, request a written declaration that
the device is safe.
Failure to clean the system jeopardises the safety.
CHIMNEY
The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.
The area of the opening 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 zone created by the shape of the
roof or any obstacles near the outlet
(see Figures 2-3-4-5-6).
