    Like the group of that era ...

    ... the Sigg Firejet has its critics who say it's a triumph of style over substance

    1354668512-1a.JPG

    It certainly looks stylish with its bottle of 'brennstoff' ...

    1267910303-2.JPG

    ... and takes a smaller bottle, so becomes a practical proposition for backpacking, at least in terms of light weight and compactness

    1267910310-2a.JPG

    There are none of those "is it a blue/red, or grey, or yellow?" MSR pump issues, because there's just the one type and it seems pretty well made, unless brass pumps and nothing less are your thing

    1267910322-3.JPG 1267910332-4.JPG 1267910341-5.JPG

    As I set about stripping down the pump, I've made sure that I've got a spares set to hand from CCS sponsor Base Camp

    1267910349-6.JPG

    The pump washer seems the weakest link with a light grade fixing arrangement

    1267910355-7.JPG 1267910363-8.JPG

    The pump has a gauze filter screen in the pump barrel upstream of the NRV

    1267910371-9.JPG

    The NRV comprises a spring and rubber ball. The bottom pair is set in the handle end of the pump rod and acts as pressure release valve when the fuel bottle's been pressurised enough. It lets out a sort of - delicacy aside - farting sound when that point's been reached. The spring is longer and of heavier gauge wire to ensure that the NRV is activated before it does, otherwise it'd be all farting sounds and no pressurised air in the bottle. Fun maybe, but you'd not get your stove to work

    NRV assembly

    1267910393-12.JPG 1267910428-13.JPG

    The pump handle's a good design and locks down

    1267910436-14.JPG 1267910449-15.JPG

    A brass thread insert takes the stove flex pipe

    1267910460-16.JPG

    Over to the stove itself now. The jet nipple, not an available spare from Base Camp, alas. I unscrewed (and refitted) mine very carefully. Cross threading would have been an unwelcome complication, given the spares situation

    1267910477-17.JPG 1267910488-18.JPG

    Final shot in this instalment. I'll post the remainder as a 'reply' to fit the whole picture set and commentary in. Oh yes, this picture caption. Top's the Sigg jet pricker. Bottom is an equivalent pricker I made up out of a Coleman generator pricker rod. I'll explain why I did that in the 'reply' to follow

    Ahh John.. With the first image you posted there (and congrats to the props dept) I can just hear Captain Kirk telling us of the final front ear, and boldly going where no man has gone before...

    Is he talking of my bomb proof outside bog ??.

    Great stuff John.

    Ok, the stove's designer intends the jet pricker to be used by removing a sump plug underneath the jet (using a coin, according to the instructions). Here's the Sigg pricker in use ...

    1267912804-21.JPG 1267912815-22.JPG

    ... and here's mine, first the sump end access ...

    1267912840-23.JPG

    ... then using the extra length the Sigg version doesn't have to clean the jet from above

    1267912857-24.JPG

    Why's that my preferred route? Well, the sump plug relies on a silicon seal. New one on the left, the one it's replacing on the right. I'm not happy risking degrading the sump washer by unscrewing the sump plug each time I want to prick the jet, so I don't go that route

    1267912875-25.JPG

    Here's the sump plug in position

    1267912890-26.JPG

    A few more details.

    The bunsen burner type sleeve valve, intended to enable kerosene or Coleman fuel to be used. I've focused on the 'B' and 'A' settings at top left and right of the picture. The 'A' and 'B' don't relate to anything as far as I can make out, because the 'benzine' setting is where the 'A' is

    1267912905-27.JPG

    Here's the rat-tail cleaner cable that's housed in the generator. It's described as a cleaning wire by the manufacturer but my experiments suggest it's needed as a damper, much like the gauze in a brass stove's fuel feed pipe. Without it, the burner definitely pulses

    1267912924-28.JPG 1267912934-29.JPG

    A bit of fun with the burner plate. It can be inserted the wrong way up ...

    1267912950-30.JPG 1267912964-31.JPG

    ... and there's a right way, that produces the correct flame pattern

    1267912980-32.JPG 1267912996-33.JPG

    Some more details

    1267913021-34.JPG 1267913031-35.JPG 1267913042-36.JPG

    The stove folds for storage

    Doc Mark's right, these stoves don't simmer. Stylish though ...

    You could listen to that single many times waiting for a sigg firejet to boil your cuppa.

    Great photos and detailed info John!

    Hi John,

    It looks like the NRV in the Sigg was designed by the same stovie as the MSR DragonFly pump designer, or somebody was looking over somebody else's shoulder. :-$

    Wonderful presentation on your Sigg.

    Good Morning, Presscall,

    John, what a wonderful report on your Sigg Fire Jet stove!! Well done, Mate!! :clap: :clap: :thumbup: :thumbup:

    Your photos our simply outstanding, too. Again, well done!

    I like the little Sigg, and with a simmering plate in place, it does work to do actual cooking, in addition to boiling water. It's small size, and easy use endear it to me, even though others don't seem to like it that much. I've used mine whilst deer hunting, and it worked very well, indeed.

    Again, great job, John! Thanks for your fine sense of humor, your attention to detail, and your great photographic skills!! Take care, and God Bless!

    Every Good Wish,
    Doc

    Thanks for the informative post.

    My eyes popped at the C-clip retaining the pump washer.

    Have replaced my washer twice (thank heavens for Base Camp!) and never saw one.

    If memory serves it doesn't come with the rebuild kit?

    Cheers from Downunder,

    Ern

    I'm trying to prepare my 20 year old firejet to put back into service for camping. Pump wouldn't work and no sign of that washer, I may have lost it somewhere in past. Leather wouldn't stay on end of rod so I've used a metal washer and cut it on one side to replicate the plastic version. Needed to use a pliers to spread the washer before fitting and to close it back afterwards, a metal c clip will be substituted when I find one some time in future. Last job for me is to replace the 20 year old fuel line. I suspect the brass connection at bottle end is made from two parts but can't figure wether they were pressed or threaded together. If I could figure that I could get a new hose made up and fitted, in meantime I may just put heat shrink around it to dampen any leak that may occur in the line. Alternatively I may cut off hose at end of the ferrules and fit a hose with 6mm internal diameter over those and use circular clamps to fit in place, however it pains me to do this as the line does not leak. I've ordered an optimus Polaris to use as main stove so the firejet will be for straight boiling as it is finicky to simmer.

    Broke the stop clip on the fuel tap almost on day one umpteen hundred years ago. Never had much success with my Firejet as it almost always burst into a ball of flame on lighting, resulting in having to clean up a sooty mess. And then I found a gas adapter! It now runs on the cheap gas cans that you buy by the dozen and burns beautifully with no mess. In my mind gas certainly seems the way to go with this stove.

    Hello Mongo,
    Great improvement. Always struggled with the soot too. Where did you get that gas adapter from? Is it that kind of kit one can buy at ali express for example? Thanks & greetings

    I love my firejet. I don't have a stuff sack for the fuel bottle though. I keep mine folded up in a cup so it makes a nice compact kit . I always liked the way it folds up.
    John, a very useful tutorial,one I will bookmark for sure.
    Thanks

    'bout time this thread got a fresh revisiting - a classic early effort with signature style already apparent - firm favourite of mine cos i actually have a sigg and with a good jet too so it runs very well i notice some siggs have a dished perforated washer under the burner and some a flat one, if it makes a difference i could not say
    would i step over a whisperlite to pick up a firejet? would i 'eck as like - but i do take the sigg now and then for a day out but the seals are looking a bit iffy so i would not like to rely on it

    @Doc Mark
    Thanks Mark for your generous comments, but like you I'm a modest guy so it's "Aw shucks" from me and "Right back at you buddy' for setting the bar so very high yourself. I'm an imitator and newcomer by comparison.

    Day-to-day, the biggest joy here on CCS is the diversity and numbers of contributors, however frequently they post or what the content might be. Though I'm happy to be a regular contributor and pleased to meet with approval, it's such a pleasure to interact with everyone here and a delight to hear what they have to say.

    John

    you are too modest M - i recall my first teaching post, my then headmaster described me as ''a modest fellow with much to be modest about''
    several weeks later i realized that i been insulted in that snide way those oxbridge types have and i tended my resignation

    no need to blow your own trumpet just accept the acclaim and get on with doing what you do, you are after all a ''colossus amongst stove dudes''
    and that's that. fullstop

    "a modest fellow with much to be modest about"

    Reminds me of some assessments rumored to exist in my Army days:

    "Sets himself a very low standard which he constantly fails to achieve".

    "His men will follow him anywhere, if only out of curiosity".

    Hi, I am reminded of the kindly professor who was asked to provide a reference for a notably lazy graduate:

    "You will be lucky to get this man to work for you"

    Honour satisfied....
