For extended side flues the flue hole centre
should be determined by extending the dashed
inclined line on the template to the side wall.
This dashed line is drawn at 44mm/metre (2.5°)
rise from the boiler. Where this line reaches the
side wall, a horizontal line should be marked.
The vertical centre line of the flue should then
be marked at 176mm from the back wall, see
diagram 5.2.
To allow for the flue passing through the wall at this
angle a 125mm hole should be drilled irrespective
of internal or external installation.
If necessary remove the wall template whilst
drilling the flue hole.
BOILER FIXING
6.1 Hanging Bracket Fixing
If previously removed, reposition the wall template
over the flue hole and mark the position of the fixing
holes for the hanging bracket, see diagram 6.1.
Mark and drill the fixing holes and secure
the hanging bracket, which is supplied in the
polystyrene pack.
NOTE: Due to the varied site conditions we do not
supply fixings and advise that the installer should
supply those which are suitable.
6.2 Boiler Fixing
IMPORTANT: With regards to the Manual Handling
Operations, 1992 Regulations, the following lift
operation exceeds the recommended weight for
a one man lift, refer to Manual Handling section
on page 6.
Lifting the boiler into position, lean the top of the
boiler slightly to the wall and position just above
the hanging bracket. Lower the boiler slowly and
engage onto the hanging bracket.
Make good the final connections.
