Table. 2 - Typology
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to the figure on the cover. Any horizontal sections of the fume
exhaust must be kept sloping slightly towards the boiler, to prevent possible condensate
from flowing back towards the outside and causing dripping.

Before proceeding with installation make sure the maximum permissible length has not
been 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.
