SIZING FUMES PIPES FOR TYPE B INSTALLATIONS
If the installation requires the combustion products to be conveyed in a type B con-
guration, the ue must be sized with reference to the following table.
Table 4.3 – Fumes evacuation pipe ducting (type B)
Useful residual head 100 Pa
Maximum length of straight DN80 pipe sections 31.0 m
Equivalent DN80 curve length at 90 °C 2.0 m
Data for sizing type B installation ues.
Example: to install a horizontal fumes pipe using n. 1 DN80 90°C curve, the maximum
extension possible with DN80 straight pipe sections is 29 m.
The following other type B congurations are also possible: B23P and B33 (for speci-
cations, see Table 4.5 Installation conguration (types B and C) 37).
Exhaust pipes exposed to atmospheric agents must be made of black polypropylene
or an equivalent weather resistant material. For sizing, refer to the established regula-
tions and the manufacturers instructions.
SIZING AIR/FUMES PIPES FOR TYPE C INSTALLATIONS
The appliance is homologated for conguration as a type C installation. The following
congurations are permitted: C13, C33, C43, C53, C63 and C83 (for specications, see
Table 4.5 Installation conguration (types B and C) 37).
