Fig. 2.1: Horizontal air/flue conduit
IMPORTANT:
The flue hole should be cut with a
slight fall to outside of 1° to prevent
rain water entering the flue.
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.
Top outlet flue exiting to rear
• For installations where the air/flue
duct is to be installed directly to
the rear of the boiler, the
installation template details the
position of the flue exit hole for
horizontal top outlet installation.
Top outlet flue exiting to side
• For installations where the air/flue
duct is to be installed to the side,
the position of the flue exit hole
can be determined by carefully
levelling across the wall from the
centre line of the air/flue duct
hole marked on the template.
• The position of the flue exit hole
should allow the flue to be
installed with a slight downward
slope of about 1° (equivalent to
10 to 15 mm per metre of flue
duct). Calculate the required fall
according to the flue length and
mark the position of the flue exit
hole.
