Vertical Flue Set
(SRD 36)
Vertical concentric
fl
ue kit Ø80/125 polypropylene inner pipe.
Discharges exhaust fumes and draws air directly from high Level.
Suitable for
condensing boilers
only.
Discharges exhaust gases and draws combustion
air at roof level by means of two concentric ducts.
The external Ø125 duct draws the combustion air
while the Ø80 plastic inner duct discharges the ex-
haust fumes.
MAXIMUM FLUE LENGTH: 8 m.
The
maximum
fl
ue length (linear equivalent) is ob-
tained by summing the length of linear pipe and the
equivalent lengths of each bend
fi
tted.
The
linear equivalent
is intended as being the to-
tal length of the duct from the connection with the
combustion chamber of the appliance, excluding
the
fi
rst bend.
The linear equivalent of additional bends is as
follows:
Ø80/125 x 90° = 0.8 m.
Ø80/125 x 45° = 0.5 m.
N.B.:
USE ONLY ALARKO TYPE-APPROVED
FLUE SYSTEMS FOR DISCHARGING EXHAUST
GASES AND DRAWING COMBUSTION AIR.
