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 terminals.
2. Consult “Table. 5 - Accessories” on page 25 and identify the losses in meq (equivalent meters) of every component, 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. 4 - Max. length separate ducts” on page 24.
