Installation
• Each appliance must have its own flue with
a cross-section equal to or larger than the
diameter of the flue gas exhaust pipe of the
stove and no lower than declared.
• There must never be two stoves, a fireplace
and a stove or a stove and a woodburning
cooker, etc. in the same environment, as the
draught of one could hinder the draught of
the other.
• Collective ventilation ducts which can create
a vacuum in the installation environment
are not allowed, even if installed in adjacent
environments communicating with the
installation room.
• It is forbidden to make fixed or movable
openings on the flue to connect appliances
other than the one used.
• It is forbidden to have other air ducts or pipes
pass through the inside of the flue even if
oversized.
• It is recommended that the flue be equipped
with a collection chamber for solid materials
and condensation located underneath the
flue inlet so that it can easily be opened and
inspected from an airtight door.
• When using flues with parallel outlets, raise
the upwind chamber by one notch.
• The flue pipe must respect the foreseen
distances from combustible materials
according to standards in force.
Chimney
The chimney must meet the following
requirements:
• Have a cross-section and inner shape like
that of the flue.
• Have a useful outlet cross-section no less
than double that of the flue.
• The chimney coming out of the roof or in
contact with the outside (for example for
open lofts) must be covered with bricks and,
in any case, well-insulated.
• Be built in such a way so that rain, snow or
foreign objects do not enter the flue and that
winds in any direction and inclination do not
hinder the exhaust of combustion products
(windproof chimney).
•
The chimney must be positioned to
guarantee sufficient dispersion and dilution
of combustion products and, in any case,
outside of the reflux area. The different
dimensions and shapes of this area depend
on the inclination angle of the roof making it
necessary to use the minimum heights (Fig.
2).
• The chimney must be windproof and higher
than the peak.
• Any buildings or other obstacles higher than
the chimney must not be too close to it.

Flue gas exhaust
Combustion products must be exhausted
through the roof.
There must be one exhaust system for the stove
(there cannot be exhausts in a flue shared with
other devices).
Flue gas must be exhausted through a pipe
diameter 80 00 placed at the back.
There must be a tee with a condensate
collection cap at the start of the upright section.
The stove flue gas exhaust must be connected to
the outside using steel or black pipes (resistant
to 450°C and beyond) without obstructions.
The pipe must be airtight. The pipes must be
sealed and insulated using materials resistant
to at least 300°C (high temperature silicon or
putty).
The horizontal sections
can be up to 2m long
.
There can be up to three 90° elbows.
The vertical pipe can be inside or outside.
The smoke duct must be appropriately
