SIZING FUMES PIPES FOR TYPE B INSTALLATIONS
If the installation requires the combustion products to be conveyed in a type B configuration, the flue must be sized with reference
to the following table.
Table 5�4 – 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°
2.0 m
Data for sizing type B installation flues.
Example: to install a horizontal fumes pipe using n. 1 DN80 90° curve, the maximum extension possible with DN80 straight pipe
sections is 29 m.
The following other type B configurations are also possible: B23P and B33 (for specifications, see Table 5.6
→
29).
Exhaust pipes exposed to atmospheric agents must be made of black polypropylene or an equivalent weather resistant
material. For sizing, refer to the established regulations and the manufacturer’s instructions.
SIZING AIR/FUMES PIPES FOR TYPE C INSTALLATIONS
The appliance is homologated for configuration as a type C installation. The following configurations are permitted: C13, C33, C43,
C53, C63 and C83 (for specifications, see Table 5.6
→
29).
To install the appliance in a type C configuration refer to the following technical data table for the sizing of the combustion fumes
outlet and combustion air intake pipes.
