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.
Suitable for condensing boilers 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 summing 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 discharge +
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.
