CHIMNEY FLUE 

 

8.1 

INTRODUCTION

This chapter about the Chimney Flue has been drawn up in cooperation with Assocosma (www.assocosma.org) 

and is based on European Standards (EN 15287 - EN 13384 - EN 1856 - EN 1443 - UNI 10683:2012). 

It provides instructions for a good and correct execution of the chimney flue but it does not absolutely replace 

the current standards which the qualified manufacturer/installer should comply with. 

Please check with your local authorities if exists any restrictive regulation which regards the 

combustible air inlet, the fumes exhaust system, the chimney flue and the chimney pot.

The company declines any responsibility regarding the bad running of the stove if it is due to the use of a no 

correctly dimensioned chimney flue which does not respect current regulations.

8.2 

CHIMNEY FLUE

•  The chimney flue or chimney is of great importance for the correct running of the heating appliance.

•  It is fundamental that the chimney flue is perfectly built and always maintained with a perfect efficiency.

•  The chimney flue must be sole with insulated stainless-steel pipes or installed on the existing chimney flue.

•  Both this solutions must be endowed with an inspection door.
