Vertical Flue System - Type V
Vertical concentric flue kit Ø60/100 polypropylene inner pipe.
Discharges exhaust fumes and draws air directly from roof level.
Suitable for condensing boilers only.
Discharges exhaust gases and draws combustion air at roof
level by means of two concentric ducts. The external Ø100 duct
draws the combustion air while the Ø60 plastic inner duct
discharges the exhaust fumes.
MAXIMUM FLUE LENGTH: 6 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 from the connection with the combustion chamber of the
appliance, excluding the first bend.
The linear equivalent of additional bends is as follows:
Ø60/100 x 90° = 0.8 m.
Ø60/100 x 45° = 0.5 m.
N.B.: USE ONLY RADIANT TYPE-APPROVED FLUE
SYSTEMS FOR DISCHARGING EXHAUST GASES AND
DRAWING COMBUSTION AIR.
