14. INSTALLING THE BOILER
After deciding the exact location of the boiler, fix the template to the wall.
Connect the system to the gas and water inlets present on the lower bar of the template. Fit two G3/4 taps (delivery and
return) on the central heating circuit; these taps make it possible to carry out important operations on the system without
draining it completely. If you are either installing the boiler on an existing system or replacing one, as well as the above,
fit a settling tank under the boiler on the system return line in order to collect any deposits and scale circulating in the
system after flushing. After fixing the boiler to the template, connect the flue and air ducts, supplied as accessories, as
described in the following sections.
If the model 24 - 1.24 - 1.14 natural draught boiler is installed, connected it to the flue with a metal pipe resistant to normal
mechanical stress, heat, products of combustion and relative condensate.
