Installation
Elbows 45˚ & 90˚ (Fig. 6.6C)
Co--- axial 60/100mm.
Elbow kits enable the standard flue kits to be offset
to overcome obstructions or ensure the correct
clearances for the flue terminal. Each elbow used
in addition to the standard flanged elbow reduces
the overall acceptable length of the flue system as
follows:
45˚ reduce length by 0,5 m.
90˚ reduce length by 1 m.

Twin pipe kits ø 80 mm (Fig. 6.7 --- Fig. 6.8)
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˚ or 90˚ accessory elbow
is used then the maximum permissible length of
either pipe must be reduced by 0.90 m or 1,65 m
respectively.
N.B: The air intake and the flue outlet must not
terminate on opposite sides of the building.

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. 6.9).
