3.6 Fume ducts

Important
The unit is a "C type" with sealed chamber and forced draught, the air inlet and fume out-
let must be connected to one of the following extraction/suction systems. The unit is ap-
proved for operation with all the Cny flue configurations given on the dataplate. Some
configurations may be expressly limited or not permitted by law, standards or local reg-
ulations. Before installation, check and carefully follow the instructions. Also, comply with
the instructions on the positioning of wall and/or roof terminals and the minimum distanc-
es from windows, walls, ventilation openings, etc.
Baffles
Boiler operation requires fitting the baffles supplied with the unit. Check that the boiler
has right baffle (if to be used) and its correct positioning.

Before installation, check the baffle to be used and 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 the table 6 and identify the losses in m
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.
