NOTES
(1) Terminals below a practicable balcony shall be arranged in such a way as to assure that the total run of smokes, from their outlet
from terminal up to outlet from balcony external perimeter, including the height of protection baluster, if any, is not less than 2 m.
(2) Distances of not less than 500 mm shall be adopted in placing the terminals, due to the proximity to materials subject to the action
of products of combustion such as plastic gutters or waterspouts, wooden jetties, etc.) unless adequate screening measures are
taken for the said materials.
The forced draught, room seled boilers, nor-
mally should evacuate the smokes on the
roof of the building.
When, in some country, it is allowed to eva-
cuate on the front of the building, the fol-
lowing distances of the terminals, have to
be complied with:
