Should my stove (Kozi Cast Iron Previa) require more air (open damper more) when running on setting 3 compared to running on setting 1? I am running my stove on high/low which is where the stove will run on setting 3 until it reaches the thermostat temp. Then it kicks back to setting 1 until the thermostat calls for more heat. My flame seems nice and lively when it is running on setting 3 but when it kicks back to setting 1 the flame is very small and seems like it is getting too much air. Thanks.
