Preparation
• Determine the installation site for
the boiler with reference to the
installation and servicing
instructions supplied with the
boiler.
• Ensure that all installation and
service clearances are available
and that the boiler flue can be
installed as detailed in these
instructions.
• Fix the paper template, supplied
with the boiler, to the wall
ensuring that the centreline of the
template is vertical using a
plumbline or spirit level.
Please note: The vertical air/flue duct
and terminal accessory (Accy.
303 600) may be shortened. The
outer ‘white’ duct should be
shortened first, then the inner flue
duct cut so that it protrudes 15 mm
out of the air duct. In case of
installation directly to the boiler
without elbows or bends, it is
essential that the roof tile/collar is
vertically aligned with the air/flue
duct of the boiler.
