IMPORTANT. The boiler must be installed in a vertical position in accordance to the installation instructions.
FLUE KITs
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.
Note. If ‘B’ packs are used on their own (either 1 piece or telescopic), then they can be fitted horizontally as the flue inside is
designed to slope 1.5 degrees.
‘D’ pack
- contains: 1 metre length of flue pipe (Functional length 950mm), 1 support bracket and instructions.
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.
additional Termination Kits
available for use with these ‘B’ packs.
Flue Deflector Kit
The resistance is the equivalent of 1 metre of flue pipe and therefore must be deducted from
any maximum flue length
High Level Flue Outlet Kit
The maximum permissible concentric flue length when using a standard (500mm) kit is 4.5 metres
Balcony Flue Outlet Kit
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
