Table. 7 - Typology
If the boiler is to be connected
INOX TECH 45 H
to a collective flue or to a single flue
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical personnel in conformity with the current regulations and be suitable
for sealed chamber units equipped with fan.
