CAUTION
LT**
total length is a reference value
for the dimensioning of the ducts of
A
(intake) and
S
(Exhaust).
Subtracting the values of
LT
repor-
ted, at values of bends* / terminals*
/ extensions* you get the value:
if > 0 = OK
POSSIBLE configuration
if < 0 = NO
WRONG configuration
Please note: these values relate to
exhausts/made by means of rigid
pipes and smooth original UNICAL.
