Turning Off The Boiler; Gas Conversion; Prolonged Shutdown. Frost Protection (Central Heating Circuit); Troubleshooting - Baxi Luna 3 Silver Space Series Operating & Installation Instructions Manual

To switch off the boiler, disconnect the electric power supply. With the gas boiler in "OFF" mode (section 3.2), the electric
circuits remain powered and the frost protection function is enabled (section 8).
The boilers can operate both on natural gas and LPG.
All gas conversions must be made by an authorised Service Engineer.
8. PROLONGED SHUTDOWN. FROST PROTECTION
Do not drain the whole system as filling up with water again causes unnecessary and harmful scale to build up inside the
boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add
some specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors).
The electronic boiler management system includes a "frost protection" function for the heating system which, when the
delivery temperature falls below 5°C, operates the burner until a delivery temperature of 30°C is reached.
The frost protection function is enabled if:
* the boiler is electrically powered;
* the gas tap is open;
* the system is at the correct pressure;
* the boiler is not blocked.
The remote control unit sends two types of signals: FAULT and BLOCK.
FAULT
Faults are signalled on the display with
The fault is identified with an error code followed by the letter E and cannot be reset
by the user.
Call the authorised Service Centre.
