2.8.1. Flue pipe examples
AISI 316 steel flue pipe with
double chamber insulated with
fibreglass or similar, resistant to
400 °C.
EXCELLENT
Refractory flue pipe with double
insulated chamber and external
concrete cladding lightened with
honeycomb material such as
clay.
GOOD
Traditional square-section clay
flue pipe with empty insulating
inserts.
MEDIOCRE
Avoid flue pipes with
rectangular cross-sections
where the larger side is twice
the smaller one, such as 20x40
or 15x30.
POOR
For square- or rectangular-section flue pipes, the internal corners
should be rounded with a radius of no less than 20 mm. For the
rectangular cross-section, the ratio between the internal dimensions
should be ≤1.5.
The sections/lengths of the flue pipe shown in the technical data table
are guidelines for correct installation. Any alternative configurations
must be suitably sized in accordance with EN13384-1.
You are advised to fit a chamber to the smoke duct to collect solid
materials located beneath the mouth of the smoke duct. This chamber
should be easy to open and inspect from the airtight flap.
IMPORTANT!
If you have doubts about the performance of your
flue pipe or if the dimensions of the latter differ from
the recommended values, it is highly advisable to
have an authorised MCZ fitter perform a prior survey
and instrumental measurement of the performance
of the flue pipe (measurement with micro pressure
gauge)
MCZ s.p.a. will not be held liable for any stove
malfunctioning if the same is ascribable to the use of
a poorly sized flue pipe installed in a way that does
not comply with the requisites listed herein.
