1. close the gas;
2. to switch o the power supply;
3. Completely empty the CH circuit (to be avoided if glycol is present in the system) and the DHW circuit of the appliance (if combined
with a storage tank). In systems that are drained frequently, lling must be carried out with suitably treated water to eliminate hard-
ness that can cause lime-scale.
