Carefully measure the distance between the
appliance flue outlet bend and the 2
nd
last
extension or bend (dimension X). Add 40mm
to dimension X to give dimension Y (see fig.
15a).
Measuring from the socket end of the last
extension, mark and cut both pipes to suit
dimension Y.
Remove the appliance flue bend from the flue
outlet and insert the inner flue pipe of the
extension into the push-fit socket of the bend
until the outer flue pipe butts against the edge
of the appliance flue bend.
Take the outer flue clip, seal, & screws (sup-
plied with the flue terminal kit) and secure the
flue pipe to the appliance flue bend.
Connect the assembled bend and extension to
the 2
nd
last extension or bend and ensure the
correct seal is made.
Finally connect the appliance flue outlet bend
to the appliance flue outlet.
NOTE
When cutting an extension to the required
length, you should ensure that the excess is
cut from the plain end of the extension. Re-
move any burrs, and check that both seals are
located properly.
You must ensure that the entire flue system is
properly supported and connected.
Seal the flue assembly to the wall using ce-
ment or a suitable alternative that will provide
satisfactory weatherproofing. The exterior
trim can now be fitted

Concentric vertical flue
(see fig. 16 & 16a)
The vertical flue terminal should be connected
directly to the appliance flue outlet. If addi-
tional bends and/or extensions are fitted, a
reduction must be made to the maximum flue
length (see table below & 3.4.4).

Vertical flue terminal and accessories
IMPORTANT
The vertical flue terminal is 1.0 metre in length
and cannot be cut; therefore it may be neces-
sary to adjust the position of the appliance to
suit or use a suitable extension.
Remove and discard the appliance flue outlet
bend.
Remove the knockout panel on the appliance
casing (directly above the appliance flue out-
let).
Using the dimensions given in fig. 16a as a
reference, mark and cut a 105mm hole in the
ceiling and/or roof.
Fit the appropriate flashing plate to the roof
and insert the vertical flue terminal through the
flashing plate from the outside, ensuring that
the collar on the flue terminal fits over the
flashing.
Insert the boiler top adapter (supplied with the
vertical flue terminal) into the appliance flue
outlet ensuring the correct seal is made. Insert
the vertical flue assembly into the boiler top
adapter ensuring the correct seal is made. The
flue support bracket (supplied with the vertical
flue kit) can now be fitted.
If the vertical flue requires extension/s or addi-
tional bend/s, connect the required number of
flue extensions or bends (up to the maximum
equivalent flue length) between the boiler top
adapter and vertical flue assembly.
