2-INSTALLATION
MAINTENANCE
The flue must always 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 boiler 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 inspection/maintenance has been performed, request
a written report that the system is safe.
Failure to perform cleaning jeopardises the system’s 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 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).
