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 reported, at values of
bends* / terminals* / extensions* you
get the value:
if > 0 = OK - POSSIBLE conguration
if < 0 = NO - WRONG conguration
(*) Values in the MT018 available on the website.
ATTENTION:
For the type of connection B23P the
room follows the same installation rules
for boilers with natural draught.
Please note:
These values relate to exhausts/
made by means of rigid pipes and
smooth original UNICAL.
Please note:
Insert a condensate collector siphon
at the base of the smoke kit because
the boiler is not fitted to receive
the condensate drain from the
evacuation system of combustion
products.
