    Hi,

    I need some help getting this stove to light. I have a 4kg lpg gas bottle and have bought a female/female adapter to connect the gas hose to it.
    Gas flows through the burners but I haven't been able to get a flame.

    Wondering if there are compatibility issues with the type of bottle vs this particular stove?

    Any pointers welcome - I'll attach some photos.

    Thanks 452152022_473376082235261_8702763077644330040_n.jpg 452176627_456012050596671_7971999487433375580_n.jpg 452278249_1640899340018987_470767162706773739_n.jpg 453709378_858153342949259_7317550441610258357_n.jpg

    Hi Jon,
    Is LPG a Propane gas ?
    On the lid of the stove I read Propane
    By changing the nozzles it should work

    Hi, thanks for your reply - yes you're right, I hadn't noticed the Propane label. The cylinder is full of LGP.
    What do you mean please by changing the nozzles? Sorry - this is all new to me!

    On domestic gas stoves, you can change the nozzles/jets depending on the type of fuel. I don't know if it's possible on this type of stove.

    Propane and butane are the most common LPG for camping stoves - in low pressure stoves with pressure regulator, they work quite similar but in full pressure stoves like this one, butane will deliver less pressure than propane and may need a different jet.
    It seem to be a regular 2396 made for the 2000 system propane bottles, primarily 2012 but it should work with any LPG vessel filled with propane and connected to a full pressure outlet.
    If you have a gas like any sort of LPG flowing through the burner heads, it should at least be igniteable above the burners. If you have bad O-rings on the valve spindles, you may hear a gas flow but it comes the easy way into the box behind the knobs and may puff there if ignited - usually inch sized small O-rings but I can't tell the size in this case.

    Thanks, I'll try find the correct Primus 2000 gas cylinder. Is there a difference in gas pressure with those bottles compared to the BBQ style cylinders?

    LPG is Propane and as Lennart said this is a high pressure stove so no regulator. Take the burners (H) off and make sure insects haven't made a home in them.
    Whilst the burners are off check the part number on the jet to confirm the stove is setup for LPG, then check for gas coming out of the Jet Nipple (I) .
    If there isn't then remove the jet and clean. There is often a brass mesh screen inthe jet. You will probably need a very fine wire to clear the jet hole.

    @Sellig33 Once I took the stove apart and saw the jets there it all made sense, see pic of how dirty they are! They are stamped 8075 - Propane. I replaced them with two spare 3.7 (Primus Power fuel, White gas) jets from my Primus Multifuel.

    @Lennart F That diagram was very helpful - thanks! Helpful info too.

    @ROBBO55 Great instructions, stove is now working beautifully!
