3.2.3. Positioning the Boiler
Each unit is supplied along with a paper template, in
the package, allowing positioning the pipes connec-
ting CH system, DHW system, gas supply, and air
intake/flue gas discharge ducts to the boiler before
installing the boiler itself.
The template is made of highly resistant paper and is
to be affixed to the wall on which the boiler is to be
mounted using a carpenter’s level. It provides all the
indication required in order to drill the holes for fixing
the boiler to the wall, the boiler is secured to the wall
using two screws and wall plugs.
The lower part of the template shows the areas to be
marked for the couplings positioning of boiler con-
nection to the gas supply pipe, water mains supply
pipe, DHW flow pipe, CH flow and return pipes.
The upper part of the template shows the areas to
be marked for positioning of air intake and flue gas
discharge ducts.
Since the temperature of the walls on
which the boiler is mounted and the
temperature of coaxial flue system do
not exceed 60°C, minimum distances
from flammable walls do not need to be
arranged.
For boilers with split pipe flue system, in
presence of flammable walls and
passages through such walls, provide
insulating layer between wall and
flue pipes.
