FLUE OUTLET
SECTION 2 - INSTALLATION
2.8 DETERMINING THE FLUE LENGTH AND FLUE PACKS REQUIRED
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 MUST be fitted horizontally as the flue
inside is designed to slope 1.5 degrees.
D Pack Flue Extension 100mm DIA 1000mm long
D Pack Flue Extension 100mm DIA 500mm long
D Pack Flue Extension 100mm Dia 2000mm long
Roof Flue Kit with Vertical Connector
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
- & 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
Soffit Kit
This kit enables fitment of an external flue below soffits.
