After deciding the exact location of the boiler, x 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, t a
settling tank under the boiler on the system return line in order to collect
any deposits and scale circulating in the system after ushing. After xing
the boiler to the template, connect the ue and air ducts, supplied as
accessories, as described in the following sections.
If the model 24 natural draught boiler is installed, connected it to the ue
with a metal pipe resistant to normal mechanical stress, heat, products
of combustion and relative condensate.
