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 ue
incorporating a terminal and rubber wall seal.
Horizontal Flue Terminal (600mm long) ‘B’ Pack - contains:
Flue turret, non telescopic single piece ue incorporating a
terminal and rubber wall seal.
Horizontal Flue Terminal (1000mm long) ‘B’ Pack - Flue turret,
telescopic ue incorporating a terminal, rubber wall seal and
instructions.
Note. If ‘B’ packs are used on their own (either 1 piece or
telescopic), then they can be tted horizontally as the ue
inside is designed to slope 1.5 degrees.
Flue Kit 203129 - D Pack Flue Extension 100mm DIA 1000mm long

Flue Kit 211038 - D Pack Flue Extension 100mm Dia 2000mm long
Flue Kit 211039 - Roof Flue Kit with Vertical Connector
When extension ‘D’ Packs are used the ue 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 tted 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 xing of ue
joints)
Only use water as a lubricant during assembly.
The ‘B’ pack terminal is classed as part of the maximum ue
length.
These ue systems incorporates a removable ue outlet
nose that utilises a push t location system. This enables the
installation of deector, high level or balcony ue kits without
the removal of the whole ‘B’ pack terminal. The appliance must
not be operated without the desired outlet nose correctly tted
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 tted 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.
‘D’ Pack - contains: 1 metre length of ue pipe (Functional length 950mm), 1 support bracket and instructions.
Additional Termination Kits available for use with these ‘B’ packs.
Flue Deector Kit The resistance is the equivalent of 1 metre of ue pipe and therefore must be deducted from
any maximum ue length
High Level Flue Outlet Kit
The maximum permissible concentric ue length when using a standard (500mm) kit is 4.5 metres
Balcony Flue Outlet Kit The maximum permissible concentric ue length when using this kit is dependant on the length
of the balcony ue outlet run which combined with the concentric run must not exceed the
maximum ue length requirement of the appliance it is to be tted to
Soft Kit This kit enables tment of an external ue below softs.
