Twin Flue Set
(SRD 20/27/36)
Horizontal twin pipe fl ue 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 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 fl ue length (linear equiva-
lent) is obtained by summing the length
of linear pipe and the equivalent lengths
of each bend
fi tted.
The linear equivalent is intended as be-
ing the total length of the duct (exhaust
dis air intake) from the connec-
tion with the combustion chamber of the
appliance, excluding the
fi rst 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.
N.B.: USE ONLY ALARKO TYPEAP-
PROVED FLUE SYSTEMS FOR DIS-
CHARGING EXHAUST GASES AND
DRAWING COMBUSTION AIR.
