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.
