Fireplace flue gas
Avoid contact with combustible materials
(example: wooden beams) and in any case
provide for their insulation with flame retardant
material. In case of pipe penetrations through
roofs or walls is recommended to use special kits
crossing, certificates, are available commercially.
In the event of a chimney fire, turn off the stove,
disconnect from the network and never open the
door. Then call the authorities.
The chimney cap
The chimney cap must respect the following
requirements:
• It must have the equivalent diameter and
internal form
of the flue.
• It must have a useful outlet diameter of not less
than double that of the flue.
• The chimney cap on the roof or that remains in
contact with the outside (for example, in case
of open lofts or attics), must be covered with
elements in brick or tile and must, in any case,
be well insulated.
• It must be constructed to prevent rain, snow,
and extraneous bodies from entering the flue
and so that the discharge of the products of
combustion is not inhibited by wind from any
quarter or strength (wind-proof chimney cap).
• The chimney cap must be positioned in such
a way as to guarantee the adequate dispersion
and dilution of the products of combustion and
in any case, must be out of the reflux zone.
This zone has different dimensions and forms
according to the angle of inclination of the roof
so it is necessary to adopt minimum heights
(Fig. 2).
• The chimney cap must be a wind-proof type
and must be above the ridge.
• Eventual structures or other obstacles that are
higher than the chimney cap must not be too
close to the chimney cap itself.
• The device should not be installed in the flue
shared.
