Error Reporting

Flashing Draft Fan Setting - This indicates that the stove is in normal operation and that the vacuum sensor detects a loss of pressure either because the door is open or because there is a negative pressure in the room with respect to the exhaust. If the problem is not remedied and the unit is still in start-up mode you get a ERR-3. If this problem happens during run mode, you will get an ERR-2.
