VERTICAL / HIGH LEVEL (HORIZONTAL)
BALANCED FLUE (WHITE SYSTEM)
VERTICAL SYSTEM
This version of the White system allows the flue to rise vertically
from the boiler to exit vertically through the roof by utilising a
vertical terminal with an integrated cowl.
The maximum flue length for this system - from the top of the
boiler flue outlet to the terminal - is 12 metres for all Grant Vortex
boilers.
HIGH LEVEL (HORIZONTAL) SYSTEM
This version of the White system allows the flue to rise vertically
within the building before exiting horizontally through the wall by
utilising a terminal with a 90° bend.
The maximum flue length for this system - from the top of the
boiler flue outlet to the outer face of the wall - is 10 metres for all
Grant Vortex boilers.
Refer to Figure 9-8 for a visual representation of the High Level
White system.
The following items are additionally available for BOTH versions
of the White system:
•
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.
Two types of locking band are supplied with each kit, as follows:
•
Type 1.
A white painted band - for connecting fixed joints
together, i.e. any joint that does not slide.
•
Type 2.
A white painted band - to cover the sliding joint on
the adjustable (telescopic) section.
! NOTE !
The locking band for the adjustable section is labelled for
easy identification.
Refer to Table 9-4 for a list of White system components and their
product codes.
