Vertical balanced flue
(White system)
Allows the flue to rise vertically from the
boiler to exit through the roof.
The maximum flue length - from the top
of the boiler flue outlet to the terminal - is
12 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.
Flexible vertical balanced flue
(Red system)
This is a flexible vertical balanced flue
system (for the 15/21 and 15/26 models
only) designed to be fitted inside an existing
masonry chimney. See Figure 9-8.
It basically consists of three sections:
•
Concentric white painted flue pipe
connected to the boiler.
•
Vertical concentric flexible flue (flexible
stainless steel flue liner inside a
flexible plastic air inlet liner).
•
Terminal assembly for chimney top
mounting.
Flue System and
Air Supply
The flue pipe seals are factory fitted and
must be
lubricated with the lubricant
supplied before assembly.
The Red system is supplied as a
separate kit. Flue extensions and 45°
elbows from the White system may be
used to extend the flue between the
boiler and the flexible section of the
system.
The maximum vertical straight length
of flue, from the top of the boiler to the
top of the terminal, is 20 metres – using
no more than four 45° elbows. Deduct
1 metre of straight flue length for every
elbow used.
If the flexible liners have to pass
around an offset inside the chimney
deduct 2 metres of straight flue length
to compensate for this.
The Grant Red system flexible stainless
steel liner is directional. The arrows
marked on the liner
MUST
be pointing
vertically upwards, following the
direction of the flue gases. Failure to
comply with this instruction could lead
to a leakage of condensate from the flue
liner.
Flue extensions cannot be cut, use
adjustable extensions where required.
Three types of locking band are supplied
with the kit.
The first type is for connecting flue
sections that butt together (2 of this type
of locking band are supplied).
The second type is to cover the joint on
the adjustable (telescopic) section.
The locking band for the adjustable
section is labelled for easy
identification.
The third locking band is plastic and
supplied in two halves. This is to secure
the plastic flexible liner to the adapter.
The flue kit includes a Black coated
terminal with upstand and is designed to
be fixed (using the screws provided) to
the top of a masonry chimney.
The flue system may be offset using 45°
elbows (ref. ELB K2145/90 models up
to 26 kW output or ELB K22 145.200 for
models 26 to 70 kW output).
No more than a maximum of four
elbows should be used per system.
