We recommend a drop in alcohol burner that fits into the stove. Unfortunately, a normal sized Sterno is too big. There are types of alcohol burners currently on the market that can fit in our gen2 stove.
The size that can be used with our gen2 stove is diameter less than 2.5in and height around 3in or less.
We plan to build an alcohol burner that fits into the stove later in 2020/2021.
