camping stove flare ups

Hi Bungarra,
The flare-up is usually due to gas condensing in the hose or pipe during cold periods, such as at night. Usually I find that shutting the gas off at night, plus arranging the hose so that it has no dips in it where liquified gas can pool seems to fix the problem.

I would suggest replacing the jets. Has this only happened since you put on a full (new fill) gas bottle ?

I have had exactly the same problem and did last week talk to a gentleman running a smaller camping store, Basically it is condensing in the line but turning it off at night wont fix it, it needs to go off after every use! your stove is designed as a high pressure stove and to use a regulator you would need to convert it to a low pressure stove, its easier to turn it off I was told "after you boil the last water for your after meal cuppa turn it off and this will prevent it" this did "fix" my problem this weekend

We had the same problem off and on for years. Tried a few things but all to no avail.

We were told it was the jets and that replacing them would fix the problem but we were unable to source the right jets for that particular model stove.

Earlier this year we fixed the problem by purchasing a new low pressure stove. It boild the billy quicker and we don't get flare ups. Cost about $60.00

We had the same problem with an old Primus two burner stove, It worked fine for 10 years and then suddenly started to flare up morning, noon and night. Replaced the jets, didn't help. Ended up dicing it and buying a new stove. The new one has a regulator on it. I do not know if this makes a difference. Certainly it does not burn as hot as the old one.

i have not had a problem since i took the following steps:

Always turn off at the bottle and let the cooker or light burn out.
Fit a little cotton wool behind the jets to act as filters.

Rational.
The gas condenses overnight. The liquid enters the burner and it flares up.

The liquid acting as a scourer also washes the internal piping and carries the dust etc into the jets.

Some others say the jets block up from foreign matter depositing itself on the jet face caused by an eddy current created by the gas vapour leaving the jet. I cannot say that this does not happen other than to say I have never had another problem since I did the two thingies above.

The Primus stove relies on the jets to control the flow of gas. (High Pressure)
Stoves like the Coleman use a regulator. (Low pressure)

The best solution of all is to dice the Primus and buy a Coleman 2 burner.
Both burners are controllable from a low simmer to full burn and there is no jets to become blocked.

I don't know a fix but right after I bought two 3.3 kg Primus bottles to replace the cheapo 1.25 kg Kmart Jackaroo bottle the stove started flaring up almost all of the time when starting. Current solution is to not worry about it.

I have an old (really old) Couger 2-burner stove. I have used it for 15 years. The stove has never flared up before, and I've never used Primus bottles before, nor anything larger than 2 kg. Maybe it's somehow related to bottle size or the brand/type of valve? Casper
