9.4 Balanced Flue System
Apart from a conventional flue, several
balanced flue options are available for
use with the Grant VORTEx boilers.
All are suitable for use with Class C2
kerosene.
None of the flue sections in the
following system can be cut.
Low level horizontal balanced flue
(Yellow system)
Available in Short (for single thickness
brick walls) and Standard kits.
Extensions are available which extend
the flue by 225 mm, 450 mm or 675 mm.
90° and 45° elbows are also available.
The maximum flue length - from the
centre of the boiler flue outlet to the
outer face of the wall - is 4 metres (with
or without elbows included). No more
than 2 x 45° or 1 x 90° elbow should be
fitted per system.
The low level balanced flue (Yellow
system) is supplied with a stainless
steel guard. This must be fitted in all
circumstances to prevent objects from
entering the flue outlet.
The guard must be fitted centrally over
the flue terminal and securely fixed to
the wall.
High level (horizontal) balanced flue
(White system)
The High Level (horizontal) balanced
flue (White system) allows the flue to
rise vertically within the building before
exiting through the wall horizontally.
The maximum flue length - from the top
of the boiler flue outlet to the outer face
of the wall - is 10 metres for all VORTEx
boilers.
The following items are additionally
available:
•
Extensions to extend the flue by 225
mm, 450 mm or 950 mm.
•
An adjustable extension of 275 to 450
mm.
•
A 45° elbow - No more than 6 x 45°
elbows should be fitted per system.
Each elbow reduces the overall
maximum length of the system by 1
metre.
