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 1,65 m
respectively.

Two restrictors with different size are supplied
with the twin pipe kit and have to be installed
between the boiler and the air intake adapter
(Fig. 6.8).
