Vertical Balanced Flue Kit
The vertical balanced flue kit is designed to be telescopic in nature and incorporates the latest 'O'ring seals. It is
therefore unnecessary for any 'cutting down' of pieces to the required size.
Please note that to facilitate the connection process, each section of pipe has a different diameter. The lowermost
pipes have the smallest diameter, the size increasing with each subsequent section of pipe. The lowermost pipes
are also the shortest, with the subsequent inner and outer sections being the next shortest. The next sections are
all the same length, however the highest inner and outer pipes have a single hole at the top above the 'O' ring seal.
Before commencing the assembly process, please make sure that you have correctly identified the placement of
each pipe section and that all 'O' ring seals are in position.
ASSEMBLY METHOD (Fig.8/9)
1. Having secured the boiler in position cut a hole
175mm diameter or square in the ceiling and roof.
2. Remove top casing of boiler and remove the flue
socket from the top of the boiler body.
3. Determine the flue length required, ensuring that the
top outer flue pipe will finish above the roof flashing
line. If possible, pre-assemble the entire flue on a flat
surface. Use the pre drilled holes at the base of each
pipe to drill 2.8mm diameter holes near the top of
each pipe for use with the self-tapping screws.
Note: The lowermost inner pipe will protrude from the
top of the lowermost outer pipe by approximately
40mm to ensure easy accessibility when fixing the
inner pipes together. The bottom sections already
have pre-drilled holes, located near to the top of the
pipes.
The flue spigot plate must fit over the inner lower pipe
before the outer lower pipe is put in position.
The flue infill plate is placed on the top casing (once
replaced), however it should be fitted around the
outer pipe before the full flue is assembled.
4. If possible to do so, lift the entire assembled flue
through the ceiling and secure in position on top of the
boiler. Fasten down with existing nuts and washers.
TO FIT FLUE PIPES TOGETHER THAT INCORPORATE 'O' RING SEALS, IT IS ESSENTIAL TO APPLY A THIN BEAD
OF LUBRICANT (E.G. WASHING UP LIQUID, VASELINE) AROUND ALL RUBBER SEALING RINGS.
AS THE FLUE SYSTEM OPERATES UNDER POSITIVE PRESSURE, IT IS ESSENTIAL TO ACHIEVE
A TOTAL SEAL ON FLUE JOINTS. APPLY A THIN BEAD OF SILICONE SEALANT AROUND
THE BASE OF FLUE PIPE BEFORE INSERTING INTO BOILER SPIGOT.
ANY PIPE EXPOSED TO THE ELEMENTS SHOULD BE PROTECTED WITH A SUITABLE MATERIAL.
WHEN ASSEMBLING THIS KIT, PLACE ALL WELD SEAMS TO THE REAR.

Note: The air inlet holes on the terminal must not be
blocked on the outside, or on the inside by the upper
flue pipe.

If this is not possible, then fit the flue piece by piece,
being aware that none of the flue joints should be
situated within the joist space.
Fit ceiling plate centrally over hole, ensuring that the
outer flue pipe has a minimum clearance of 25mm
from any combustible material. Pack space with glass
fibre insulation.
Fix pipe bracket (where necessary) to roof space and
fit waterproof flashing (not supplied) around outer flue
pipe at roof line.
Fit clamping strap (supplied) around joint line of
terminal and upper flue pipe. Use foam sealing strip
inside clamping strap.
Fit the apron cravat (air inlet cover) to the terminal
using 4 self-tapping screws (supplied).
