Connection with separate pipes
fig. 14 - Examples of connection with separate pipes (
= Air /
= Fumes)
Table. 4 - Typology
For the connection of separate ducts, fit the unit with the following starting accessory:
fig. 15 - Starting accessory for separate ducts code 010031X0
Before installation, check the baffle to use and that the maximum permissible length is
not exceeded, by means of a simple calculation:
1.
Establish the layout of the system of split flues, including accessories and outlet ter-
minals.
2.
Consult table 6 and identify the losses in m
eq
(equivalent meters) of every compo-
nent, according to the installation position.
3.
Check that the sum total of losses is less than or equal to the maximum permissible
length in table 5.

= Air /
= Fumes)
Table. 7 - Typology
If the boiler is to be connected

to a collective flue or to a single flue with natural
draught, the flue or chimney must be expressly designed by professionally qualified tech-
nical personnel in conformity with the current regulations and be suitable for sealed
chamber units equipped with fan.
