Increasing the fan speed more than necessary will cause some heat to be thrown out of the
chimney. Air that comes out suddenly and in large quantities during combustion will cause
adherence in slags.
"Fuel Feed", "Fuel Standby", "Gearmotor On / Off", "Manual Fuel Feed" buttons will not work in
"Wood Mode".
While automatic feeding, you can switch to "Wood Mode", but you cannot switch from "Wood
Mode" to automatic feeding. To switch from “Wood Mode” to automatic feeding, you can
switch to automatic feeding after pressing the “ON / OFF” button and turning off the boiler.
The boiler covers and the hopper cover should not be left open during combustion.
