1. Connect the flue outlet with the short-
est possible run of flue pipe to the
chimney. Avoid sharp bends.
Note
The cross-sections of the flue pipe
and the chimney must match that of
the draught hood connector. Maintain
a distance of at least 100 mm
between the flue pipe and combusti-
ble materials.
2. Create a test port in the flue pipe (see
diagram).
3. Thermally insulate the flue pipe (if
required).
2. Carry out a tightness test.
Note
For the tightness test, use only suita-
ble and approved leak detecting
agents (EN 14291) and devices.
Leak detecting agents with unsuita-
ble constituents (e.g. nitrides, sul-
phides) can lead to material damage.
Remove residues of the leak detect-
ing agent after testing.
