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.
4.4 Rear and Side Flue Application
Select the boiler location and flue application, with due regard
to the terminal position.
Take the template from the boiler pack and temporarily position
it on the wall, making sure that the minimum clearances are
maintained, see diagram 1.2.
For a rear flue mark the position of the flue as diagram 4.4.
For a side flue, extend the centre line horizontally left or right to
the corner adjacent surface where the flue is required to exit to
outside. Mark the position of the centre of the flue and boiler,
see diagram 4.4.
4.5 Flue Hole Cutting
Having marked out the flue centre cut a hole for the flue using,
preferably, a 115mm minimum core drill.
4.6 Wall Mounting Bracket
Reposition the template, making sure of dimensional alignment
with the flue hole.
Mark the boiler fixing points and mounting bracket position, see
diagram 4.5.
