[steyrman]

For some reason the gas fire in my caravan works fine for half an hour then the flame goes very low virtualy off i have never had this problem before the bottle is full and in a box with a lagging jacket on it for the cold does anyone know the reason for this ?

Are you useing Butane or Propane?

Butane freezes before propane ,so use propane the red canister most appliances can use both but you need a different regulator

Not quite true.

 

The Butane does not freeze as you indicate. It does however cease to boil and produce any vapor at 0 Degree C

 

However given the current outside temperatures, you advise regarding the use of Propane in preference to Butane is correct.

Propane will gas better at a lower temp,both will see pressure drops at bellow 4degrees , have used both at low temp,in my army days ,setting up field kitchens,prefered pressurised petrol but was banned in some European countries ,never had freezing problems with them,

Is the regulator freezing up? If it is have a quick look herehttp://www.propane101.com/propaneregulatorfreezing.htm

Liquid Propane will still turn into a vapour at around -30c

 

Liquid Butane will only turn into a vapor at +1c

 

Or there abouts

light your farts, they work in sub zero temps

[stoggieman]

Is there a thermostate in your caravan? If so is it set right? Alsohas the regulator been of the gas pipe? Could be a small insect or a spider partialy blocking the gas valve before the burner.

No stat in the caravan and the regulator has never been of the bottle had loads of caravans over the years never had this problem before

[stoggieman]

Would be tempted to gently wire brush the burner then vacume it also check the flame failure device for gunge then rais it gently with a pair of thin nosed pliers but be gentle
