5.2 Rear and Side Flue Application
Having selected the 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, see diagram 5.4, making sure that the minimum
clearances are maintained.
For a rear flue, mark the position of the flue as diagram 5.4.
For a side flue, extend the centre line horizontally (taking into
account the required fall towards the boiler) left or right to the
corner of the adjacent surface where the flue is required to exit
to the outside.
Alternatively, the increase in the centre line height over a
distance “x” is given by H=0.035x. Mark the position of the
centre of the flue, as diagram 5.4.
5.3 Flue Hole Cutting
Having marked out the flue centre cut a hole for the flue see
diagram 5.4A for minimum core drill size for various wall
thicknesses.
This will allow for the 35mm per metre (2 o ) fall towards the boiler.
Note: If required, an optional Wall Liner Kit, part No.900862, is
available, complete with fixing instructions.
5.4 Wall Mounting Bracket
Reposition the template, making sure of dimensional alignment
with the flue centre lines.
Mark the boiler securing screws and mounting plate position,
see diagram 5.5.
Drill holes and plug, fit the securing screws, allowing sufficient
clearance to accept the keyhole fixing brackets and secure the
boiler mounting bracket to the wall.
