For the connection of separate ducts, fit the unit with the following starting accessory:
fig. 12 - Starting accessory for separate ducts
Before installation, check the baffle to be used and make sure the maximum permissible
length has not been 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 the table 6 and identify the losses in m
eq
(equivalent metres) of every com-
ponent, 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.

to a collective flue or 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.
