The template to fix the boiler on
the wall
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 fit two G3/4 stop cocks (available on demand) on the
central heating system flow 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 fit settling tanks 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 fixed on the template connect the flue and air ducts
(fittings supplied by the manufacturer) according to the instructions given
in the following sections.
