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 functioning of the heater and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and
checked by a skilled chimney sweep at least once a year. Once the check/maintenance has been performed, request a signed report stating
that the system is safe.
Failure to clean the system jeopardises its 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).
