INSTALLATION
The resistance is the equivalent of 1 metre of flue pipe and therefore must be deducted from
any maximum flue length
The maximum permissible concentric flue length when using a standard (500mm) kit is 4.5 metres
The maximum permissible concentric flue length when using this kit is dependant on the length
of the balcony flue outlet run which combined with the concentric run must not exceed the
maximum flue length requirement of the appliance it is to be fitted to
This kit enables fitment of an external flue below soffits.
Total Maximum: 9 metres - minus any flue kit options or bends
Total Maximum: 8 metres - minus any flue kit options or bends
Total Maximum: 7.5 Metres - minus any bends
Total Maximum: 5 Metres - Concentric Flue and 17m flue pipe only. For additional details

Installation and Servicing
pipe work used and the bracket is located as close to the collar
as possible. The bracketing must ensure a 1.5 degree fall back
to the appliance.

Only use water as a lubricant during assembly.
The 'B' pack terminal is classed as part of the maximum flue
length.
These flue systems incorporates a removable flue outlet
nose that utilises a push fit location system. This enables the
installation of deflector, high level or balcony flue kits without
the removal of the whole 'B' pack terminal. The appliance must
not be operated without the desired outlet nose correctly fitted
in place, ensuring the side location dimples are in line with the
mounting face allowing the correct sealing of the components.
It is IMPORTANT that all attachments are fitted in accordance
to the installation instructions provided with them.
The TURRET supplied in the 'B' Pack has an upper combustion
sample point with a screw cap seal and a lower air sample
point with an air stopper seal. Ensure all caps & seals are in
place.
