2 - INSTALLATION INSTRUCTIONS
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).
