12. Boiler size
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.
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.
Connect the condensate outlet to the siphon supplied with the boiler. Connect the siphon to a drain,
making sure there is a continuous slope. Horizontal sections must be avoided.

Remember that the presence of foreign matter in the heating system can adversely affect the operation
