The A04 alarm appears on MCZ pellet stoves when the flue gas temperature is too high. This is a safety alarm.
Resolution
- Check that the flue pipe is not blocked and that the stove is not dirty or obstructed with combustion residues.
- Cancel the alarm on the control panel by turning theON-Remote-OFF button on your unit to "OFF" for about 10 seconds.
- Wait until the screen displays "OFF", then put the switch back to "Remote".
- Clean the unit: empty the ashes, clean the brazier and vacuum
- As soon as "OFF" is displayed on the remote control, you can restart the stove
If these checks are not sufficient, contact your local chimney sweep so that he can check the condition of the flue and the stove.
