Eterinox - Chimney Kit
Terminals and elbows
The Architectural Terminals/Chimney Pots series produced by Fibrotubi S.r.l. includes devices placed at the end of a chimney/flue, allowing the dispersion of combustion products even in the presence of adverse weather conditions. The features that characterize this series are:
- Having an outlet cross-section no smaller than twice that of the chimney/flue it is inserted into.
- Being shaped in a way that prevents the penetration of rain and snow into the chimney/flue.
- Being constructed in such a way that, even in the case of winds from any direction and inclination, the evacuation of combustion products is still ensured.

POSITIONING OF CHIMNEY POTS AND TERMINALS ON BUILDINGS WITH FLAT ROOFS RELATIVE TO TECHNICAL VOLUMES WITHOUT OPENINGS

Discharge clearances based on the distance of the terminal from obstacles without openings.

| Distance (mm) | Discharge height Distance (mm) | Discharge height | |||
| X ≤ 2000 X > 2000 | Z + A2 B | X ≤ 1200 X > 1200 | Z + A2 B |
The symbol Z refers to the height (mm) of the obstacle or technical room; for the heights A2 and B, refer to table 1.1 (UNI 7129 part 3).
Discharge height indications:
| Symbol: A2B* | ||
| Description: Height above the virtual ridge line stretched between the roofs of adjacent buildings or obstacles or technical rooms in the absence of openings/windows. Height above flat roofs or closed parapets. | ||

| X = 3000 3000 < X = 5000 X > 5000 | Z + A2 J B | X = 2500 2500 < X = 4000 X > 4000 | Z + A2 J B |
In the presence of a balcony or terrace (instead of a simple window), the height X must be calculated starting from the balustrade (whether open or closed) and not from the building’s wall.
The symbol Z refers to the height (mm) of the obstacle or technical room.
