1. Install the flue pipe with a rise to the chimney (pref-
erably 45°).
Flue pipe (internal diameter):
Max. flue pipe length: 3000 mm
2. The entire flue pipe with cleaning aperture must be
gas-tight.

■
Install a flexible connection piece in the flue to pre-
vent sound transmission from the flue gas fan.
Additional on-site sound insulation measures may be
required.
Never brick the flue pipe into the chimney.
■
Let the flue pipe connector project about 10 mm into
■
the chimney. This prevents condensate or rainwater
from the chimney running into the flue pipe.
