4.3.2 Using the boiler template
(fig. 13)
4.3.2.1 Once a suitable location has
been chosen, fix the paper installation
template on the wall ensuring that the
centerline of the template is vertical
using a spirit level or plumb line.
The template shows the positions of
the fixing holes for the boiler hanging
bracket and connection group. The
template also shows the position of
the flue exit hole, for use where the
air flue duct is to be installed directly
to the rear of the boiler, e.g. where
the boiler is installed on an outside
wall and the flue terminates directly
behind.
4.3.2.2 Mark on the wall the positi-
ons of the hanging bracket (2) and
connection group fixing holes (3). Drill
two holes Ø 10 mm for the hanging
bracket, and similarly drill three holes
Ø 8 mm for the connection group.
(Note: Use the alternative fixing holes
where necessary).
4.3.2.3 Rear exit flue.
Mark the position of the centre of the
flue duct and its circumference, e.g.
by drilling through the template (1).
4.3.2.4 Other flue options.
Refer to the installation instructions
supplied with the flue accessory for
detailed instructions on other flue op-
tions such as vertical RSF flues, flue
runs to the side of the boiler and the
use of additional flue elbows and
bends etc.
4.3.2.5 Remove the template from the
wall and plug the drilled holes using
the wallplugs supplied.
4.3.3 Fitting the boiler hanging
bracket and connection
group.
Secure the hanging bracket and
connection group securely to the wall
using the screws supplied. (If the con-
dition of the wall is poor it may be
necessary to use additional or alterna-
tive fixings to ensure adequate sup-
port).
NOTE: If the boiler is to be fitted in a
timber framed building ensure that the
brackets are secured to a substantial
part of the timber frame capable of
taking the weight of the boiler.
