What is this ?

This vent connects the LPG bottle and the hose on our Oceanis 36cc which we have bought in France.

Does anyone know what function it has ?

Pressure regulator/reducer.

Makes the stove more predictable.

You need the correct capacity regulator for the appliance being supplied. ALL propane appliances should have a regulator. between them and the tank someplace.

The yellow button on that one most likely is a cover over the adjustment screw. This is something you shouldn't mess with. Once set at the factory that type of regulator will be very reliable for up to 40 years. When they quit giving the correct output its time to replace it because it will have a failed diaphram and they are not repairable.

Re: What is this ?

according to GOK the yellow button is for purging after bottle change. it is a non adjustable 30 mbar regulator. they do make a marine version.

Re: What is this ?

And there is no "LPG" in your gas bottle, but propane or butane.

Please explain what you believe to be the difference between "LPG" and "propane or butane".

Both propane and butane are "liquified petroleum gases".

Commercial LPG is generally a mixture of the two depending on where and when you buy it.

See for example

Re: What is this ?

Hello,
On the picture you can see a blue bottle. In France these boat a equiped with "Camping gaz" 5Kg bottle. These bottle are originaly filled up with butane. Butane is better than propane because it gives more heat for the same weight of gaz and freeze near 0. Propane freeze by 5.

Not sure what happened to the link in my previous post. It was supposed to be:
LPG Propane/Butane mixture - myLPG.eu

You've got that temperature thingie backwards.

Butane is good unless you are trying to use it in cold temperatures.

Butane's boiling point is -1C. Propane's is -42C

When the air temperature gets down towards freezing, butane becomes problematic. When drawing gas, the cylinder becomes colder than ambient - depending on how fast you are trying to draw it and how big the cylinder is, it can drop to the boiling point of the butane well before the ambient air temperature gets there.

Even at about 5C, gas pressure is very low and you don't get much work out of the butane.

Once it is below boiling point, you won't get any gas out of the cylinder.

Not a problem with propane until the temperature gets close to -40 (C of F, take your pick )

I learnt that the hard way.
Many years ago, when I bought my first boat in a Pommy Autumn, I soon found the issue there. First morning, frost everywhere and I needed to take the Butane cylinder to bed with me to get it warm.
Next week, I took a propane cylinder to the boat with me!
