Horizontal Flue Set (SRD 36)
Horizontal concentric
fl
ue kit Ø80/125 mm polypropylene inner pipe adjustable through 360°.
Discharges exhaust fumes and draws air from atmosphere.
Suitable for
condensing boilers
only.Dis-
charges exhaust gases and draws combus-
tion air by means of two concentric ducts.
The external Ø125 duct draws the combus-
tion air while the Ø80 plastic inner duct dis-
charges the exhaust fumes. The discharge
duct can be connected directly to the out-
side or can be connected to a suitable com-
bined
fl
ue system.
MAXIMUM FLUE LENGTH: 8 m.
The maximum
fl
ue length (linear equivalent)
is obtained by summing the length of linear
pipe and the equivalent lengths of each
bend
fi
tted.
The
linear equivalent
is intended as being
the total length of the duct from the connec-
tion with the combustion chamber of the ap-
pliance, excluding the
fi
rst bend.
The linear equivalent of additional bends
is as follows:
Ø 80/125 x 90° bend = 0.8 m.
Ø 80/125 x 45° bend = 0.5 m.
N.B.:
USE ONLY ALARKO TYPE-AP-
PROVED FLUE SYSTEMS FOR DIS-
CHARGING EXHAUST GASES AND
DRAWING COMBUSTION AIR.
