I've recently acquired a 535 and I'd like to run it on Coleman type fuel (Fuelite here in NZ) According to Base-Camp the burners are either No. 207 or No. 9007. The 9007 is listed as Paraffin/petrol. How can I tell which one I have? What is the difference between them and what would need to change on a 207 to burn properly? Any comments much appreciated. Thanks!
Hi There are good reasons not to run a 535 on coleman type fuels. Cost of fuel being a big one but also this stove is simply not designed for volatile fuels. It usually has an air screw on the filler cap rather than a safety valve so it can over pressurise. Also if the Non retern valve at the base of the pump leaked it would leak fuel out the front of the stove (down the pump tube). While it could be done on a kero burner 535 is would be very unwise (IMHO). As to the burners on your stove, a photo would help. Dan
Hi Dan, thanks for your reply. I've attached some burner images and one of the cap. You're right, it doesn't seem to be a pressure relief valve. But I may have one that will fit! I'd still like to know how to identify the burners - google images aren't much help here. Does anyone know how to tell a No. 207 from a No. 9007 burner? In the end I may just use kero - it will be the only one - my other stoves are all Fuelite burners. It would be nice to not have to take two fuels. Cheers Colin
Correction, sometimes these have an air screw but I don't think your does, pretty sure you bought yours on trademe recenty so I have seen pics of it, I am not sure but I think that cap may be able to release pressure some how.
Oh, we both posted at the same time. And there is the cap I was meaning. The centre part kind of floats from memory, I don't have one to check how it works. The burners are kero ones, not meths ones. They can burn white spirits but even with the cap I would not advise it. Someone will help with burner I.D. If you really want to burn white spirits in a stove of this size people swear by coleman suitcase stoves. Personally I have never had one of those but they can be very cheap. Dan P.S. Careful with the wick in the priming shoot that runs down the the spirit cup. The wick is asbestos.
I've looked at the Coleman suitcase stoves, I think somehow they seem to lack character. I've got a Campingo as my stove-in-a-box. Yes, scored it on trademe, second go at getting one as I was seriously outbid for one before Easter. I see you're looking at the parts one listed too. I've not pulled this one apart yet, but it may need some spares... Thanks for the heads up on the asbestos wick, I assume that it could be replaced with a oil lamp wick? Cheers Colin
You can do with out the wick. It does help with lighting, without the wick you need to be a bit quicker with the match after pouring the meths if you want to light from above. The 535 you have is a nice one. Should be good for years to come. Dan
Hello All, This thread made me look more determently at the caps I have on these 535's, plus one on a spare tank. Although a Primus tank NOS, it arrived with a typical Optimus 8/99 fuel cap, while the connectors on the tank are meant for paraffin burners. All caps have some kind of relieve built in, the Optimus version with the wellknown cross-slitted vent that is, of course, rock solidly seized. This happens to be sitting on a dedicated alcohol stove, but do realise how easy these caps can be interchanged. Finally, that rather mysterious cap this thread is putting in the limelight, and prompted me to take it apart. I think by depressing the centre you could release some pressure, but only when the cap is not screwed home, which sort of defeats that purpose. There is no spring or other gizmo present, so I can not arrive at some satisfactory conclusion. I also can not think of another model appliance I have seen these caps on other than the 535 dual stoves. As to the initial question, most appliances, if not all, that are designed to use paraffin like this one, will happily burn other, more flammable fuels like petrol etc. But the risks are already outlined by Dan and very valid. I see no real practical problem to get some paraffin /kerosene for this excellent stove, and the caloric value of gaseous paraffin ranks perhaps higher than lead-free petrol. Congratulations on this acquisition: these are very practical stoves, as they are low and hence stable. Also, if the taps are OK you can keep the pressure on, while using it during the day. To avoid a spill and thus quite a stench, it is best to release any pressure while away, like in cabins or boats. Regards, Mike
I have found some diagrams of the 207 burner, found on Base-Camp. But have not seen anything yet on the 9007, has anyone got info on this? One other thing, there is a number 303758 stamped on the control spindle support. Some sort of production code date stamp. How is it interpreted? Cheers Colin
Thanks Win, good to know. I suspected that might be the case. Looking at my inner cap it has no holes. The 207b diagram has holes so it's looking more like mine is a 9007. Is this possible for a 1958 535? Cheers Colin
Hi Colin, don't worry to much about the holes in the inner cap, they come with or without them and are otherwise the same size. These holes are supposed to work as a "damper", like a car muffler but their effectiveness is not really proven. Caps with or without the holes are perfectly interchangeable so yours is not necessarily the original one. All the best, Wim
Hello. I think the #9007 burner Basecamp are refering to, is a special solid cast Optimus kerosene burner that is usually installed in stainless marine stoves. A replacement for the Optimus kerosene 207 - 207b burners. Please see this link to an Australian provider - http://www.oillamps.com.au/Kero.html#KEROSENE In the Kerosene Stoves section on that page, look under the burner repair artical. There are 3 photos showing a damaged regulating burner, the Optimus #9007 marine burner and another undamaged Primus burner. My own preference would be to not use a petrol stove in a confined space like a boat cabin, caravan or house. I would rather stick to the far safer kerosene burning models like the 535 you have now. Cheers, John
So I got around to firing it up today... on kero you'll all be relieved to know but the filler cap leaked, on inspection the piece of cardboard washer wasn't up to the task. Not having much at hand I cut a disk from some gasket material which seemed to do the job. Both burners fired up without any hassle, nice! In a post above Mike shows the gasket from the filler cap. It looks like some sort of molded rubber button. What material is it and does it matter what is used here? Cheers Colin
It is a flat bit of nitrile rubber, shaped by being on the stove. You can buy a seal from brassmonkey on trademe.
