Technical data
e dimensions of the shas must ensure a minimum gap betwe-
en the outer wall of the smoke duct and the inner wall of the sha:
30 mm for circular section shas and 20 mm in the event of a
square section sha (Fig. 29).
Maximum 2 changes of direction are allowed on the vertical
section of the ue system with a maximum clearance angle of 30°
with respect to the vertical.
e maximum vertical extension using a Ø 80 ducting system is
27 m, the maximum extension includes 1 Ø 60/100 to Ø 80/125
adapter, 1 87° Ø 80/125 bend, 1 m of horizontal pipe Ø 80/125, 1
90° Ø 80 ducted bend and the roof terminal for ducting.
To determine the C92 ue system in congurations other than
that described (Fig. 31) one must consider the following head los -
ses:
- 1 m of concentric pipe Ø 80/125 = 1 m of ducted pipe;
- 1 87° bend = 1.4 m of ducted pipe;
Consequently one must subtract the equivalent length of the part
added to the 27 m available.
