For all of our single stoves, maximum number of ring burners is 2. However for each ring, there are yet two rings of flames. So when you light it up, there are total of 4 flame circles. We carry two burner stoves and three burner stoves in our product section. For the two burner stove, each burner has two rings. So number of total rings is 4 (number of total flame circles is 7).
