Help Diagnose Canister Stove Issue (Under Burn?)

OK, we progress.
Clearly there is little threat to the canister and your immediate environment, given the temperatures sensed by your hand.

Now, the temperature of the stove body. Your skin has a very abrupt response to anything over 40 C. Just 50 C could have this effect of intense pain. A protective response you see.

Can I suggest you repeat all the measurements with the stove cold and then after running the stove for, say, 3 minutes and then turning it off. Measure the stove body first and quickly before its temperature changes by much. It is not really abnormal for the stove body to get hot – that is one of the reasons they put a long wire handle on the needle valve. Then move on to the other 3 positions.

This will give us 9 temperature readings: ambient via conventional thermometer (not the IR unit), plus cold and hot for each of the 4 positions.

Yes. I have had ice form on a canister with the stove on high. This is plenty to reduce pressure and slow the burn rate a LOT.

James is not the only one to have had that problem!

Idea: send the stove to Hikin’ Jim for testing.

Roger said it more succinctly than I did, but that’s essentially what I was trying to convey:  If your hand doesn’t draw back in response to touching the canister then there isn’t a problem.  Even if the silver rim of the canister valve housing gets hot, that’s not the end of the world.  The canister pressure is determined by the temperature of the inside of the canister, and if the main body of the canister is reasonably “touchable,” then you’re in good shape.

As for my testing your stove, I suppose I could, but I don’t think there’s any need for that.  Your stove seems fine.  The first one you had though, that was a bit more scary.

Touch the side of the canister opposite where the fuel is near the bottom of the canister.  If it’s hot to the touch there, turn the stove off.

Thanks, all. I will use it and report back in the unlikelihood that this one has an issue as well
