Traditional concentric flue system, Figure 3a, with a maximum length of
5000mm. The flanged flue elbow is designed with 3° slope towards the
appliance so that the condensate can easily drain off. It has to be
considered that for every metre horizontal flue length the terminal exit
centreline is approx. 45 mm higher than the elbow’s centreline.
The standard telescopic terminal is 615mm max length and 430mm min
length, but can be cut to a minimum flue length of 250mm, which is
suitable for single, 100mm (4"), brick walls.

Standard concentric (ø100/60) vertical flue application, Figures
3b, 3c, through roof attics with a maximum length of 12000mm.
The kit comprises of the roof terminal, flashing kit, vertical
adaptor with sampling point and bracket.
The maximum length is measured from the top of the appliance
casing to the underside of the air cowl.
For installation details refer to the flue kit instructions.

If the standard horizontal terminal is likely to cause nuisance to a
neighbour or buildings, because of excess pluming, then this
particular flue kit raises the flue gas outlet point to a higher
elevation with the minimum amount of changes. The flue gas duct
is teed-off from the concentric part and covered by an 80mm
outer tube to protect the flue duct from freezing. The air in-take
remains at the lower level (see Figure 3d).
If choosing this option then the external flue duct length should be
taken into account when calculating equivalent flue length.
For installation details refer to the flue kit instructions.
