Technical Dept. - All rights reserved - Reproduction prohibited
MAINTENANCE
The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draught, thus compromising
the efficient operation of the product and, if large build-ups accumulate, they can catch fire. The flue and chimneypot 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 safety.
CHIMNEYPOT
The chimneypot is a crucial element for the heating appliance to work properly: we recommend a wind proof chimneypot (A), see Figure 7.
The area of the opening for smoke
extraction must be at least double
the cross-section of the flue/lined
system, and arranged so that smoke
outlet 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).
