V
ertical Roof Terminal
For use wher
e an external wall is not
available. For installation details, refer to Supplement 1 at the rear of
this booklet.
These optional kits may be used with the standard flue kit to
produce an extensive range of flue options. Examples are
illustrated in Figures 2 and 3. Variations upon these illustrations
may be used providing that the following rules are strictly obeyed.
a)
The maximum/minimum per
missible allowable length of the flue
system is:
Horizontal flue terminal (Right and Left) - maximum 2500 mm (99 in)
Horizontal flue terminal (Rear)
- maximum 2000 mm (79 in)
Horizontal flue terminal
- minimum 300 mm (12 in)
Vertical flue terminal
- maximum 4000 mm (158 in)
Vertical flue terminal
- minimum 565 mm (22 in)
b)
The standar
d terminal must always be fitted horizontally. The vertical
terminal must always be used if a vertical outlet is required.
c)
The flue must only ter
minate in a horizontal or vertical position.
However, 90° flue elbows may be used to drop the height of
the flue system by 500 mm.

CONCENTRIC AIR/FLUE DUCT SPECIFICATIONS
•
•
•
The appliance is supplied complete with a standar
d telescopic flue
kit. This comprises a standard duct and a terminal duct and can be
used for flue lengths between 506 mm and 820 mm without cutting
the ducts. To use terminal duct for flue length between 300 and 506
mm the ducts need cutting. Avoid swarf and sharp edges to maintain
telescopic function
The following additional concentric kits are available as optional
extras.
Extension duct
(each extension extends the flue length by up to
767 mm)
90
° Extension Elbow
(Allows an additional bend in the flue and
has an ‘equivalent length’ of 767 mm.) This elbow is mechanically
different from the flanged elbow supplied as standard with the
appliance, but has the same equivalent length of 767 mm.
45
° Extension Elbow
Allows an additional bend in the flue and
has an equivalent length of 384 mm.
V
ertical Turret Socket
For use with elevated horizontal flues and
vertical cowls.
