e dimensions of the shas must ensure a minimum gap between the outer wall of the smoke duct and the inner wall of the sha: 30 mm
for circular section shas and 20 mm in the event of a square section sha (Fig. 32).
Maximum 2 changes of direction are allowed on the vertical section of the ue system with a maximum clearance angle of 30° with re-

To calculate the length of the ue, simply add, for each component you intend to use, the corresponding value indicated in the
column "Length equivalent to m of pipe" in the table in par. 1.14, and check that the resulting sum is equal to or less than the
maximum length indicated in par. 1.15.
