Hi All My first post, so I hope it's in the correct place. I've been trying to run a Coleman folding oven with a single burner Coleman 533. My first trial (some time ago) was aborted because the fuel tank became too hot to touch. The oven reached about 120C/250F. I had the stove on a large rectangle of aluminium and the oven on a frame above it. ChuckW gave me a couple of ideas by email, so I've just tried again with the stove on a brick paver (on the ground) and the oven on a frame about 1" above the burner. The oven reached 150C/300F in 4.5 minutes but by then the top of the fuel tank was too hot to touch. Also, this time, I had made an aluminium reflector collar for the stove, in an effort to keep some of the reflected heat off the tank. I've got pix of it, if it's any help. Perhaps the 533 and the oven are not going to be successful running mates but I thought they should, given others use single burner stoves to fire the oven. By the way, I have a Kovea Booster+1 which I use in a Trangia 25 (with the Optimus adaptor). I tried this little stove (on Coleman fuel) under the oven, with the oven on a couple of bricks and the burner about 1" to 1.5" below the stove. It got to 220+C/430F (from cold) quickly and maintained it. Air temp about 25C/80F. I'd prefer not to have to use the Kovea under the oven because I use it in the Trangia. If anyone has any ideas, I'd appreciate it. Cheers Leigh
Hi leigh, welcome to the Forum!!! Try using Alu foil to wrap the oven, that way you can throttle back a bit! The 533 is a great little backpacking/car camping stove, but the 'suitcase' stoves do a better job with the oven... Show us a picture of your setup, suggestions will flow!
Usually, the ovens are used on the Coleman suitcase stoves where the fuel tank is nowhere near the burner, as you know it is outside of the case when in use. Also the burner on a suitcase is about 2 inches below the grate where it sounds like you are a bit closer. Maybe try a bit further up so the heat isn't being caught by the 533 and can escape out the sides? I believe the oven, since the heat has nowhere to go but back down from the oven is overwhelming the 533. On a suitcase, the sides of the case get quite hot. Hopefully, you'll come up with some ideas for this. Good luck! sam
Steve and Sam, that was quick. We've got the suitcase stove but we now travel in a small campervan, so space is limited. We never cook inside the vehicle. Steve, here are the pics of the oven and 533 and the reflector collar on the 533. I'll also try to include the pics of the Kovea Booster+1 and oven.
Leigh, your stove is really to small for the oven. Yes it will work but there are so many things which have to be exactly right to make it work proper you are better off using a different setup. I strongly suggest a larger stove if you have one in order to get the heat up to a proper cooking temp for any kind of baking. As already suggested you need to wrap the oven in aluminium foil to prevent all the heat loss out the hinges etc.. lance ps I'm not saying this stove won't do it but the dangers related to it's use are not worth the benifits. lp
the 533 puts out a massive amount of heat. Its one of only 3 of my stoves that boil a litre of water in under 3 minutes 30.With normal pots the tank doesnt even get warm. maybe makeing the heat shield fit a little lower might help
I think your heatshield on the stove needs to be moved so that the entire burner assembly is above it. Try to make is so that there is an air gap between the shield and the tank as well. The burners on these get REALLY hot and that appears to be radiating the fount with gobs of heat. I think the stove will put out plenty of heat without the foil wrap around the oven, but will certainly conserve fuel so you don't have to run it in blast furnace mode. Just my observation. Mike
Hi All Thank you for your ideas. I can't get back to this before the weekend. I'll try another (lower) heat shield and see how it goes. I'll also try the stove on the ground, giving about 35mm between the burner and the oven base. Leigh
Try a Coleman model 500/500A - this would be nice compromise between a full size suitcase and a smaller "back-pack" type stove. The 500's have plenty of power for an oven I suspect and a much more stable platform for your oven. Tom
Hi Folks Thank you for your suggestions. I tried changing the position of the heat shield and lowering the burner further from the bottom of the (Coleman) oven but the tank still got too hot to touch. I also tried the stove with an oven I made - it's 9" X 9" X 12" (works well with a Kovea Moonwalker). The Coleman 533 was OK with this for 25 minutes (after which the tank started to get hot). It took only 3 minutes to get it to 200C and then kept it there, with a bit of juggling of the fuel control. Looks like I might stay with the home-made oven. Leigh
Hmm.... Did you make a new shield with a smaller opening that shields the radiant heat from the burner, or just lower the original? I would have thought that would have made a huge difference with an air gap and tight fit around the box housing. But perhaps there is just too much heat conducted south with that big burner. I guess I was wrong about the foil too. Those "ovens" are pretty loosely built. Mike
Greetings, Folks, IMHO, the Coleman oven was never meant to be used with the smaller, single burner stoves. Instead, it works best with larger stoves, and the regular Coleman suitcase stoves. Some have had fairly good luck, too, using "plug and play" stoves, which have a separate fuel tank. But, putting a small stove underneath a fairly large oven (compared to the stove) is just tempting fate, and not worth the return, as far as I'm concerned. If you want to use an oven with your small stove, look for an Optimus Mini-Oven. It will work perfectly, as it was designed to be used with small stoves. I do not believe that the Coleman oven was originally meant for such use. For what it's worth.... Take care, and God Bless! Every Good Wish, Doc
