INSTRUCTIONS PERTAINING TO THE INSTALLER
13. BOILER INSTALLATION
Decide upon the boiler location, then tape the template on the wall. Connect the pipework to the gas and water inlets
prearranged on the template lower bar. We suggest you t two G3/4 stop cocks (available on demand) on the central
heating system ow and return pipework; the cocks will allow to carry out important operations on the system without
draining it completely. If you are either installing the boiler on a pre-existent system or substituting it, we suggest you also
t settling tank on the system return pipework and under the boiler to collect the deposits and scaling which may remain
and be circulated in the system after the purge.
The boiler has to be directly connected to an efcient chimney which unloads at the outdoor the products of combustion. The
connection section between boiler and ue must be at least the same as the connection boiler section. The chimney always
has to be under good conditions and does not have to have openings or cracks that can determine dispersions of draught.
