Twin pipe kits ø 80 mm (Fig. 6.7)
Various twin (split) pipes kits and optional acces-
sories (elbows) are available to assist in the ter-
mination of the flue where the boiler is installed in
a location remote to an outside wall.
These kits allow for separation of the air supply
pipe from the pipe that discharges the exhaust
gasses. Consequently it is possible to extend the
flue system to a greater distance than that pro-
vided by the standard horizontal co---axial flue.
If either an additional 45
û or 90 û accessory elbow
is used then the maximum permissible length of
either pipe must be reduced by 0.90 m or 2,75 m
respectively.
90 û =---2,75 m
45 û =---0,90 m
Fig. 6.7
The graph in Fig. 6.8 demonstrates the allowable
equivalent lengths for the air supply and flue ex-
haust pipes.

Vertical--- roof kit (Fig. 6.9)
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 û and 90 û elbows can be used to offset
the flue route.
max = 8.5 m

Vertical flue kit --- condensation
When fitting the 80/125 l flue kits where the Equiv-
alent Flue Length exceeds 3 m a condensate col-
lector and syphon are required.
If the appliance normally operates at minimum
output power at very low temperatures (e.g. 40 û C
return / 60 û C flow), the above equivalent length
should be reduced to 1 m.
The syphon must also be connected to a suitable
drain.

from your Supplier for details or contact Biasi UK
