General information

Before installing the appliance and flue gas routing, consult the
responsible building authorities and district flue gas inspector to
establish whether there are any objections.
The flue duct kit is a component of the CE-approved system. Therefore,
only genuine flue duct kits may be used.
The permissible maximum balanced flue line depends on the appliance
and the number of deflections in the balanced flue. For calculation, see
chapter 5 from page 11.
