C3X Roof vertical exhaust and inlet
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to fig. 25. 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 installation, 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 table 8 and identify the losses in m
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 6.
