Twin Flue System- Type H
Horizontal twin pipe flue kit Ø80/80 in polypropylene adjustable through 360°.
The dual pipe system discharges exhaust fumes and draws air from atmosphere in two separate ducts.
Horizontal twin pipe flue kit Ø80/80 –
Ø60/60 in polypropylene adjustable
through 360°.
The dual pipe system
discharges exhaust fumes into a chimney
and draws air from atmosphere.

Suitable
for

only.
Discharges
exhaust
gases
and
draws
combustion air through two separate Ø 80 ducts.
MAXIMUM FLUE LENGTH:
Ø80/80: 50 m
Ø60/60: 30 m
The maximum flue length (linear equivalent)
is obtained by totalling the length of linear
pipe and the equivalent lengths of each
bend fitted.
The linear equivalent is intended as being the
total length of the duct (exhaust dis air
intake) from the connection with the combustion
chamber of the appliance, excluding the first
bend.
The addition of a bend has the effect of
increasing the linear equivalent length of the
duct as follows:
Ø80 x 90° bend = 1.5 m.
Ø80 x 45° bend = 1.2 m.
Ø60 x 90° bend = 1.8 m.
Ø60 x 45°bend = 1.5 m.
