    Second lighting observations.
    In this stove, Sterno paste (jelled alcohol) in the primer cup is perfect. It leaves a residue behind, but it stays put and it can be shaped into a mound for more volume. This stuff is awsome. It burns really hot. As soon as the stove is lit and can sustain itself on kerosene fuel, it gets red hot. The sterno residue burns away. "There is nothing like the smell of Napalm in the morning."

    Fuel: Add a small amount of fuel injector cleaner to the fuel. I found that lighting the stove worked well this way. I noticed some use a 30/70 petrol to kerosene mix. You can get by with a lot of kerosene and a small amount of fuel injector cleaner. I added about 20 ml to the bottle. I used this method with diesel (50-100 ml) in a different stove in the past.

    Sterno paste is great, but it leaves a residue. This is not a problem with the stove here, but it is really hard to clean off brass parts on a Butterfly pressure stove. The rule of thumb is if the primer cup sits in the fire, the residue goes away. If it sits under a burner, you will be painfully reminded of it every time you light the stove. It leaves its ugly mark in the primer cup.

    This stove is like using a flame thrower. It would be nice for boiling water rapidly or cooking in a wok. If you want to simmer, use a Butterfly pressure stove. They are much better for that. Overall, I like the Butterfly stove more than this one.

    I added a copper wire to the generator tube. I warapped it around the top of the tube. This helps greatly with lighting a heavy fuel. I will post photos soon.

    The instructions for this stove state that Kerosene and Diesel will burn in the stove. Diesel will never vaporize properly. I tried it as an experiment. Yellow flame results. After awhile, the generator tube will cool and the burner will resemble a camp fire. Luckily the flames are restricted to the stove's superstructure. I am using the correct jet for the heavier fuels.

    Kerosene will burn with a small amount of volitile fuel added. I use fuel injector cleaner. Basically, this stove will be my butane gas stove (with a jet switch). I am terribly afraid of using gasoline. Kerosene is about as good as it gets, and it is a hassle.

    Here is the stove burning diesel. At this point, the stove cooled and the vaporized diesel turned into liquid. What a mess!

    It may be a bit of an assumption but does 30 and 35 on the jets mean 0.30 and 0.35 mm ?
    If it does, these seem just a tad larger and smaller respectively than the values given by Primus in the manual for their Omnifuel. So I'd be curious to know if the Omnifuel jet will fit these Chinese versions and if they perform any better on kerosene for it.
    Primus state that diesel with a 0.28 mm jet will give a very sooty flame, take a long time to prime and need frequent cleaning so the behaviour here does not seem all that surprising.
    Regards

    I wrapped the generator loop with thick brass wire.
    It improves heat transfer or increases heating surface to vapourise the heavier fuels effectively.
    With that modification & the addition of extra material in the priming well I can burn 100% paraffin. Just because I can does not mean to say I would do so habitually.
    As they come the stove will not safely use paraffin.
    As for diesel.. As far as I know at present it is only a fuel of last resort even in a true multi-fuel stove offering from the likes of Primus, Optimus or MSR.

    BTW: I read Optimus outsources manufacturing of their stoves to China.
    I wondered why the Nova+ looks rather like my BRS-8.

    I know you posted this a while back but could I ask how the BSR - 8 is holding up for you? I just ordered one and I am trying to do as much research as I can on the stove. I am kind of surprised by the decent to good reviews. Anything you can add to what you have already said would be helpful. Thanks

    Hi,

    Firstly, the stove is LOUD and powerful! It burns very well on Coleman type fuel (white gas I think you call it over there) and bottled gas. I never tried mine on kerosene as I don't think it was designed to do so. Enjoy yours!

    Best regards,

    Wim

    Thank you very much. I have watched several you tube reviews and I am excited to get it. Thanks for your time.

    There's a leak on mine where the hose screws onto the pump but I got it for my scouts to use on butane and it fits the bill very nicely. It's cost was low enough that I'm not over fussed about liquid fuels. But I agree it's a loud beast.
    Regards

    I did that! I have a Trangia 25 (from the late 70's... it didn't have a burn adapter cut, so I purchased a newer windscreen), and an Esbit! Used it when I went on a business trip, and used butane to cook my meals! Works well, though you have to preheat the stove with butane!

    Hi,
    I've just bought a BRS-8B.
    I've tried 3 differents fuels.
    Is their some place where you can "translate"/find equivalent between the commercial name, the "scientific composition" and other common name. The bottels of fuel I have are written in 3 languages : French, Dutch and German. So I can't be sure of a correct english translation.

    How do you manage ?

    It was my first test and the manual of the BRS-8B is only in chinese. I've finally understood that their was 2 size : 30 and 35.
    Some fuels didn't work so it's maybe because I use the default 35 size.

    Here is my notation : french / german / deutch / scientific (fr/de/nl)

    Working with 35 : Essence à bruler / Brandbenzine / Brandbenzin / 50% Hexane & 50% n-Pentane

    Not working with 35 : Alcool à bruler / Brennspiritus / Brandspiritus / Ethanol > 83%
    Not working with 35 : Pétrole lampant / Lampenöl / Lamppetroleum / Kérosène/Kerosine/Kerosin

    I also have one. They are a quite good dual fuel burner that has a useful heat range. A little noise but less than a dragonfly. The weaknesses are well documented so keep an eye on loose crimps on the fuel hose and deteriorating o rings of which there are lots. Ive had failures in the pump o rings but common size and viton is a permanent repair. The originals are not viton. The brown colour suggests a butyl rubber which is a marginal choice at best. There are 2 o rings in the burner end of the hose which cant be replaced easily. Also watch for leaks in the pump body. I have fixed one by a method documented on this site but Im not going to put my name against that repair.

    I would advise using other 'O' rings than the spares supplied. Somebody said Viton??
    I had the 'O' ring in the gas connection start to leak, because it was flattened. I managed to turn the thing over as a temporary solution.
    I have not had the issues with leaking seals in the hose or pump problems - yet. Famous last words.
    These stoves do not seem to be made with materials to stand sustained rough use as they come.
    How hard is it to rebuild the stove using Viton 'O' rings?
    I still don't use paraffin much in this stove.
    Just because some of us have got away with it I am not advocating its use.

    @lhanneus

    Welcome

    In the 'Links' section of this site you find one for here.

    http://fuel.papo-art.com/

    I've not checked your questiin against the list, but I would be surprised if it doesn't answer yours.

    Tried to fire the BRS-8 burner adapted for the Trangia.
    Piddling fuel out of the rotating hose joint at the tap end.
    I need a complete set of 'O' rings for the entire stove to render one safe to use again.
    The spare burner's hose seems to be OK, but I don't trust it now.

    I bought mine from a on-line vendor based in the PRC.
    Are these stoves officially imported & do those use better quality 'O' rings?

    I am glad that I didn't have an inferno to deal with today.

    Does anyone have a list of the sizes of the 'O' rings needed?
    Viton is immune to attack by petrol/ petroleum spirit?

    @Primus 96 take the pump apart before you commit to buying o-rings. I think the plastic in mine was distorted so the new seals didn't have a chance.

    There is a 'B' version. I don't know if they actually have made improvements or not. Different pump designs and better seals to pass muster for sale in the EU would be essential.
    Mine lasted around seven years, which isn't bad.
