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 wall, connect the flue and air ducts, supplied as accessories, as described in
the following sections.
If natural draught boilers are installed, connect them to the flue with a metal pipe resistant to normal mechanical stress,
heat, products of combustion and relative condensate.
