corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture,
leave at least 5 cm for ventilation and maintenance;
- installation of an ambient thermostat will favour a greater
comfort, a more rational use of the heat and energy saving;
the boiler can also be connected to a programming clock in
order to manage ignition and switching off during the day or
week.
