CHIMNEY CAP
Description
A device placed at the top of the flue to facilitate the dispersion of combustion products into the atmosphere.
Technical requirements:
▪ it must have a section equivalent to that of the flue;
▪ it must have a useful section not less than double the internal section of the flue;
▪ it must prevent the penetration of rain and foreign bodies and ensure the discharge of combustion products
in all weather conditions;
▪ it must ensure adequate dilution of the products and be positioned outside the backflow area;
▪ it must be free of mechanical means of suction.
▪ the outlet position must be outside the backflow area (*) (refer to national regulations to identify the backflow
area);
▪ must be built always at a distance from antennas or dishes, and never be used as a support.
EXAMPLES OF CORRECT CONNECTION TO THE FLUE
1 Installation of flue with hole for the passage of the pipe increased by:
▪ minimum 100 mm around the pipe if communicating with non-flammable parts such as concrete, bricks, etc.;
or
▪ minimum 300 mm around the pipe (or as per the dataplate) if communicating with flammable parts such as wood,
etc.
In both cases, insert suitable insulation between the flue and the floor.
Check and respect the flue dataplate, in particular the safety distances from combustible materials.
The above rules also apply to holes made in the wall.
2 Old flue, ducted with the creation of an external door to allow cleaning of the chimney.
3 External flue made exclusively with insulated s/steel pipes, i.e. with double wall: all well-anchored to the
wall. With antiwind grille.
4 Ducting system using T-pieces, allowing easy cleaning without disassembling the pipes
