    Referred to in the PLC as an upside down gasoline lantern. It has a vertical pump and a do-nut shaped tank.

    Can anyone point me to some instructions for this lamp or give me some idea how to light it (in words of no more than two syllables, please...) [-o< :whistle:

    David,

    It's an "instant light" lamp and the procedure is the same as for other lamps of that ilk i.e. add fuel and pressure then stick a lighted match up through the hole in the bottom of the globe and open the valve 1/4 turn. When mantle burns bright, open valve all the way. Add more pressure if needed.

    You'll see that the lamp can't be overfilled because of the tube which extends from the filler down into the tank.
    25 to 30 pump strokes should be enough pressure to start with.
    The cleaning needle control should be horizontal and be pointing towards the left i.e. underneath the valve wheel.

    Here's what I found with my KAMPLITE:
    It's a bit slow at getting fuel through at first so unless you use matches which are a foot long, crack the valve and wait until you hear vapour start to spit into the mantle, close the valve ! Light your match and insert it, then open open the valve 1/4 turn etc. etc.

    Henry.

    Henry,

    Funny you should mention foot-long matches. I bought a stash of long matches (not really a foot long, more like 4 1/2 inches) specifically for lighting gasoline "instant light" lanterns.

    David

    For those of us brought up on kerosene lanterns, these "no pre-heating" gasoline lanterns can be quite intimidating at first. I always practice lighting them (first after fettling) with the globe off so that I get used to the quirks of the particular lantern. There less chance of a contained explosion that way...

    Cheers

    Tony

    Thanks, Henry - that's great! :thumbup:

    Yes, you're absolutely correct - I'm quite intimidated by this one (to say the least!) :-& :D . It's mainly the lack of fettling that worries me. I couldn't even find out how to remove one single part to allow me to check inside for tightness of seals etc. (never mind actually fettling it) before I get on to the lighting of it.

    OK, Matt - I'll start a list of stuff I'm taking to Newark 2018. I'll also put on the Coleman 555GL that Neil asked to see about 10 years ago... :oops: :doh:

    David,

    Assuming the only differences between your THERMOS and my KAMPLITE are a different name and colour, there aren't many seals to check.
    Turn the lamp upside down, undo and remove the three nuts which hold the globe holder ring.
    Lift out the globe and the white enamelled reflector. This will give you access to both the generator jamb nut and also the gland nut on the cleaning needle control.

    Undo the valve wheel gland nut and remove valve stem. Take out the two screws from the slotted band below the tank and remove the band to get at the union nuts on each end of the fuel tube between valve and vapouriser.

    If you really want to go all the way, you'll have to undo the fuel feed from tank to valve and unscrew the three posts which the reflector etc. fasten to.
    Turn the lamp right way up and undo the two small nuts on top. Lift off the top plate, slotted ring and pull out the inner chimney. Take off distance pieces and pull out inner chimney. You will now have access to the two screws which hold the last two pieces together.

    Henry.

    Thanks, Henry - that's brilliant. :clap: :thumbup:

    I just feel the need to check over the various unions before I put fuel in the tank and set fire to it... :whistle:

    You're welcome.
    Looking again at your Thermos, I've just noticed that the pump is "at the rear", whereas on the Kamplite, it's at the front - directly above the valve. Without having the two lanterns side by side, I can only assume that this is the only major difference in construction and that the information I gave in my last post is correct.

    Henry.

    @David Shouksmith
    Just had a play with my KAMPLITE.
    Fill with fuel - 1.5 imperial pints.
    25 pump strokes. In retrospect, 20 would have been enough.
    It took 23 seconds before fuel vapour came through and the lantern came to life.

    Allowed lantern to go cold before re-lighting.
    Still took 25 seconds before vapour came through and had to add another 5 pump strokes.

    Be prepared !

    Henry.

    I have a couple of these types. I used to have a great deal of trouble firing them up. Blow torch up the spout and lots of heat and they flared up and generally behaved very badly. Then I read the instructions and they "Instant" light just as Henry described. Slow fuel feed but they run just fine with a match. ::Neil::

    Thanks, Neil - I've a bit too much on at the moment so lamps are taking a back seat for a while. When I can see my way clear, I'll give the Thermos a try... [-o<
