Boiler Installation; Boiler Size - Baxi Luna 3 System HT Gebrauchsanleitung Für Den Verbraucher Und Den Installateur

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.
WarnInG:
Take special care when filling the heating system. In particular, open any thermostat valves in the system,
ensure the water enters slowly in order to prevent the formation of air inside the primary circuit until operating pressure is
reached. Lastly, vent any radiators in the system. BAXI declines all liability for damage deriving from the presence of air
bubbles in the primary exchanger due to the incorrect or imprecise observance of the above.
