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 that the maximum permissible length
is not exceeded, by means of a simple calculation:
1.

Completely establish the layout of the system of split flues, including accessories
and outlet terminals.

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.
