Trivet not turned over correctly ... add a large frypan or as I've seen done, a BBQ plate ..... AND LOTS of people use a folding wind break around the stove .... which just adds to the problem. I've seen these things flame out from poorly fitted canisters (father in law has 2x and I cringe everytime he uses them as he's a bit slap happy).
Before we got the camper we were using 2x Coleman 533 single burner pressure stoves (replaced all our old out of date gas cylinders). They work fantastic on shellite or ULP .... Sit a pot stand over the stove, add a large frypan, and wrap a wind break around the setup, and the fuel tank gets to insanely high temperatures (way way too hot to touch) ... and that's pressurized Shellite/ULP in a heavy steel pressure cylinder
under the flame/burner ...
... not a lightweight steel tin can
next to the burner ....
I'd be eerrring on the side of safety until there's a clearer outcome on the fair trading notice.
For the saftey of the lowest common denominator .... Darwin award anyone ?
