4.1 Unpacking
Open the carton, check the items supplied against the boiler
pack contents list on the flap, see diagram 4.1.
4.2 Flue Position and Length
Determine flue applications, length and terminal position before
starting.
Refer to diagram 4.2 or 4.3.
Note. If a longer flue duct is required DO NOT extend the
ducting.
A 1, 2 or 3metre flue system and terminal MUST be used, for the
100FF and 1 or 2 metre only for the 120FF.
Note: If required, an optional Wall Liner Kit, part No.452481, is
available, complete with fixing instructions.
4.3 Flue Preparation
All flue assemblies are designed for internal installation (optional
wall liner is required), given that there is sufficient clearances
opposite to the flue for the installation of the flue.
If there is insufficient clearance the flue can be installed from
outside.

For a wall thickness up to 300mm, provided that there is
sufficient space and the optional wall liner kit is used the flue can
be fully installed from the inside.
For a wall thickness of over 300mm the external flue hole will
need to be made good from the outside. This applies also if you
use the flue kit without the optional kit, irrespective of wall
thickness.
