This C-type unit must be installed using the inlet and fume exhaust ducts supplied by the manufacturer in con-
formity with UNI-CIG 7129/92. Failure to use them automatically invalidates every warranty and relieves the
manufacturer of any liability.
For fume ducts longer than 1 m, during installation take in account the natural expansion of the materials when
the boiler is operating.
