It's like when I bought a Calor Gas cooker in a camping shop back in the 70s and the guy there tried to put it in while smoking a cigarette. Silly bugger didn't have a clue. You were supposed to unscrew the burner, drop the canister in and then, slowly screw the burner back in. He had gas pouring out everywhere and I still don't understand why he didn't go up in flames.
