Flipside, how are you connected? Do you have the hose directly into the 20lb tank and the hose directly into the stove? On the stove side, are you going through the roughly 10" pipe that you would normally screw on the 1lb canister to?
The 10" pipe contains a regulator and you must go through a regulator for the stove to work. The regulator can be on either side of the hose, however you must have a regulator for it to work (and only one).
