I need an outdoor propane stove to do my canning on. I have 2 AA pressure canners, the 15.5 quart and the 921, and I think I'm going to add another 921. I have a glass top stove and it does okay with the smaller one, but I can't use the 921 on it, so I'm going to buy a 3 burner camp stove and can outside. I'm looking at the Camp Chef stoves, but they have a very high BTU output and say NOT to pressure can on them, only WB canners. They have adjustable flames right? Will these not go low enough heat to safely pressure can on? Recommendations needed please! I do want a triple burner... so I can run two canners at a time and use the third to keep hot water in.
