Isnt this just a gimmick ? The secondary burn below the firebox instead of above like modern efficient stoves.this fire might look good for a while but with burn rate would not last an hour.
Hi David, in this model, the bottom lever is called the “High output and low output” controller. It is the air control. After the burner is up to temperature (after approximately an hour of operation) it can be pulled out to low output if desired.
