2.4.3. Poor flue
If not all the requirements indicated
previously have been met, smoke may
escape from the appliance into the room in
which it is installed when the firebox door
is opened. This is because the flue is unable
to generate enough updraught.
Before doing anything else, the installer
should correct deficiencies in the
installation, bearing in mind: the material,
insulation, diameter, airtightness,
cleanliness, height, verticality/straightness,
chimney crown, etc.
If sufficient updraught is not achieved
by correcting the flue installation, Lacunza
supplies an accessory for exceptional cases:
a part which seals the top of the front part
of the appliance and helps prevent smoke
escaping into the room. Logically, this
reduces both the view of the fire and the
loading aperture on the appliance.
Figure No.6 - Accessory to help in the
event of downdraught as a result of a poor
flue
This accessory should be ordered from
the factory and, considering that the
problem is the result of a poor installation,
must be paid for by the person ordering
the part.
