Added this stove to my collection recently, I love the pump stoves and cant resist adding these European rare ones, well in Canada at least. i understand this model has a reputation for melting the dials and i think i know why. I think this happens because they leave it in Priming mode too long and like my Coleman stuff without the correct pressure will start to leak the fluid back down on the fount and this can turn it into a big fireball at this setting. I had no issues lighting this stove and the priming setting worked great. I monitored to see if the dial was getting hot enough to melt and after over an hour of continuous running did not see melting temperatures even when i was boiling water; a couple of liters using my portable pots. Water came in handy to kill weeds but mostly i wanted to run the stove to see why the dials had some melting on them when i got it. This thing went down to a very small simmering flame and i left it running like this for over 30 min and at full for the next 30 min or so boiling water.
