- optional extra kit, to extend the flue.

N.B.
If the measured flue length is
only just above
these sizes,
it may be necessary to shorten the standard flue before
adding extension duct(s), in order to prevent interference
between flue duct connectors and the boiler flue elbow.
For side flue option
PROCEED TO FRAME 20
.
10 DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED
Use a maximum of two extension ducts only. When using 90
o
elbow
kits, each elbow is equivalent to 1 metre flue length.
Calculate the total length of flue by the following:
Rear flue length = Dim. W + 79mm (3
1/8
")
Rear flue length with stand-off channels = Dim. W + 109mm (4
3/8
")
RHS flue length = Dim. R + 220mm (8
5/8
")
LHS flue length = Dim. L + 96mm (3
3/4
")
Note.
These figures include the length of flue entering the
flue turret socket
