14. 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.
When the boiler is xed on the template connect the ue and air ducts (ttings supplied by the manufacturer) according
to the instructions given in the following sections.
When installing the 240 i - 1.240 i models (boilers with natural draught), make the connection to the ue using a metal
pipe which will provide resistance over time to the normal mechanical stresses, heat and the effects of the combustion
products and any condensation they form.
