Vertical--- roof kit (Fig. 6.10)
This kit allows vertical termination of the flue pipe
through the roof. The kit is 1.2 m in length. Exten-
sion pieces (Co--- axial) are also available which al-
lows the flue system to be extended to a total
overall maximum permissible length.
Optional 45° and 90° elbows can be used to offset
the flue route.

Vertical flue kit --- condensation
When fitting the 80/125 l flue kits where the equiv-
alent flue length exceeds 3 m a condensate collec-
tor and syphon are required.
If the appliance normally operates at minimum
output power at very low temperatures (e.g. 40 ° C
return / 60 ° C flow), the above equivalent length
should be reduced to 1 m.
The syphon must also be connected to a suitable
drain.
Please, see the boiler accessory leaflet available
from your Supplier for details or contact Biasi UK
