Boiler Installation; Boiler Size - Baxi Luna 3 Avant Series Instructions For The User And The Installer

Decide upon the boiler location, then tape the template on the wall. Connect the pipework to the gas and water inlets prea
ranged on the template lower bar. We suggest you fi t two G3/4 stop cocks (available on demand) on the central heating
system fl 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 fi 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 fi xed on the template connect the fl ue and air ducts (fi ttings supplied by the manufacturer) according to
