G'day Ryan,

No, there aren't any frames separately available for the Double Ring Burner. The pot supports for this model are molded into the casting for the unit.

Good question, Bob, and not one I can answer with 100% confidence as I have not used it as such. Going by previous customer feedback though, I think either this or the triple ring burner option is a good option for use with camp ovens, for a few reasons.

Firstly, the heat is spread wider than with just a single burner stove, so you can have the heat turned down but still spread evenly. Secondly, going by feedback, high and low settings are pretty good. The triple ring burner, for example, gives you the option of turning the gas up and down, as well as controlling how many rings you have burning at once, so once things are warm, you can just leave the small inner ring on to keep it warm, or turn just the outer ring on for a rolling simmer.

Long story short, I think either the double or triple ring burners will be fine for what you are seeking.
