Hi all, new to the forum!

We were away camping at Rathdowney a couple of weeks ago and around 6pm we went to fire up the gas cooker and POW! the gas flame was around 30cm high, the gas was spluttering, so switched it off. Attempted again and same thing happened. I can only put it down to a temperature thing, as gas was in the bottle, it was connected all ok.

Anyone else experience this and any advice?

Thanks

Were you using LPG gas or Butane? Butane doesn't combust very well when it's cold. It could be something to do with your air to fuel mixture perhaps.

If you leave the cylinder valve open without the stove in use and there is a drop in air temperature, the gas in the flexible hose will condense into liquid LPG. This liquid will pass to the burner without vaporising and ignite from the liquid state causing the flame to flare. It is not particulaly dangerous other than possibly igniting close articles.

To avoid this situation, always close the cylinder valve when not using the gas. This is good safety practice anyway.

What Allan said, but close the gas cylinder valve and let the gas burn out so there's no gas left in the hose.

Also try to keep the hose going uphill from the cylinder to the burner with no low spot for liquid to accumulate.
