Note
■ Prevent the return of condensate cre-
ated inside the flue system by suitable
on-site measures (condensate trap).
■ Close the condensate drain connec-
tors if they are not used. They are
designed to drain any condensate col-
lected in the start-up phase.
Note
Connect all flue pipes free of load and
torque stress. Flue pipe joints must be
gas-tight.
