INSTALLATION
4.3
PREPARE THE WALL - Fig. 11
1.
Decide upon the position of the boiler taking into
account the clearances required for servicing and
the flue terminal position.
2.
Tape the template to the wall (ensure it is level
and the right way up) and mark the position of the
holes for the boiler mounting bracket. If rear exit
flue is used, mark the position of the hole for the
flue.
3.
Side exit flue - Continue the horizontal centre line of
the flue across the wall to the side wall, then along
the side wall 235 mm (ensure the lines are horizontal).
This will give the position of the centre of the hole for
the flue.
4.
Cut the 110 mm diameter hole (or use a 107 mm
core drill) in the wall for the flue.
Note: For internal fitting of the flue using the
sealing collar supplied, cut a 127 mm diameter
flue hole using a 127 mm core drill.
5.
Drill the fixing holes (10 mm dia.) to accept the
No. 10 plugs supplied. Using the screws supplied,
fit the mounting bracket.
