Actually, the gas burns without a flame. The catalyst lowers the

roughly like that.

But it says "Electronic instant ignition system".

With the catalytic heads, you turn on the gas and then fire the igniter.
It lights with a flame which burns for a few seconds to heat the
catalyst and then goes out (or you blow it out). The catalyst then glows
red and produces lots of heat, but there no flame any more.


Of course. Yes, you're both right (Sid & John). I remember now.
