-
In case of using a metallic and insulated chimney already existing, before installing the boiler it is advisable
to verify that the chimney has the right dimensions to allow a correct evacuation of the burnt gases and to
clean its interior.
-
In case of using a brick chimney already existing, it is necessary to fit it with an internal metal casing in
order to avoid water condensing in all its length. If it is not possible to do it, it is advisable to install a new
insulated chimney, preferably made of stainless steel and in accordance with the current regulations.
