Telescopic Flue'B' pack - contains: Flue turret, telescopic flue incorporating a terminal and rubber wall seals.
horizontal Flue Terminal (600mm long) 'B' pack - contains: Flue turret, non telescopic single piece flue incorporating a terminal
and rubber wall seals.
horizontal Flue Terminal (1000mm long) 'B' pack - Flue turret, telescopic flue incorporating a terminal, rubber wall seals and instructions.

designed to slope 1.5 degrees.

When extension 'D' Packs are used the flue duct must incline 1.5 degrees away from the appliance, to allow the condensate to drain
back to the boiler and out of the condensate drain. It is recommended that a support bracket is fitted on every 1 metre of 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.
Optional Flue Finishing Kit - UIN 155988 & Concentric Flue Screw Retaining Kit (Optional Kit of mechanical fixing of flue joints)
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.

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.
