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 6 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 5.
