2.6 Fume ducts
The unit is “C type" with sealed chamber and forced draught; the air inlet and fume exhaust must be connected to one
of the exhaust/inlet systems indicated below. The unit is approved for operation with all the Cxy flue configurations spec-
ified on the dataplate (some setups are given by way of example in this section). Some configurations may be expressly
limited or not permitted by local regulations, standards or laws. Before proceeding with installation, check and carefully
observe the above-mentioned prescriptions. Also, comply with the provisions concerning the positioning of wall and/or
roof terminals and the minimum distances from windows, walls, ventilation openings, etc.
B
This C-type unit must be installed using the fume exhaust and inlet pipes supplied by the manufacturer in ac-
cordance with UNI-CIG 7129/92. Failure to use them automatically invalidates every warranty and relieves the
manufacturer of any liability.
A
For fume exhaust pipes longer than 1 metre, during installation take into account the natural expansion of the
materials when the boiler is operating.
To prevent deformations leave an expansion space of approx. 2-4 mm for every metre of pipe.
