Ventilation of the rooms
The boiler must be installed in an adequate room in
compliance with the standards in force.

FOR BOILERS WITH NATURAL DRAUGHT
To connect the ue gas exhaust pipe, local and na-
tional standards must be observed
In the event the boiler is replaced, ALWAYS re-

CAUTION
LT total length is a reference value for the dimen-
sioning of the ducts of A (intake) and S (Exhaust).
Subtracting the values of LT reported, at values
of bends / terminals / extensions you get the
value:
if > 0 = OK - POSSIBLE conguration
if < 0 = NO - WRONG conguration
Cps = Loss coefcient specify
Value referred to curves / terminals / extensions
Ø 60 - Ø 80 wich as to subtracted from LT.
