I have a Coleman 533 dual fuel single burner stove, that is acting strange.. I filled it with new Coleman fuel, and after pumping it up, and lighting it, I get the large orange flames until it settles down and heats up, then it starts to sputter, and burns blue, then orange, then blue, then back to orange, and never settles down to just blue. pumping up the stove to increase pressure does not solve the problem. Then when i turn the stove off, a flame appears at the bottom of the burner assembly where it sits on the fuel tank and where the generator goes into the assembly. First time i lit the stove, I had to use a hose to put out the flames, after i shut it off by the valve. I took the generator off and noticed that the cleaning rod does not go all the way through the orifice at the end of the generator. I took the cleaning rod (really a wire with a needle at the end) and stuck it through the orifice manually to clean it. I put the stove back together, but as of today havent gotten around to trying it again. I cant remember where i read this, but i remember a thread on some board that mentioned the cleaning rod and pricker on the 533 doesnt go all the way into the orifice at the end of the generator like it should and it causes alot of problems with the stove. has anyone else heard about this? and is there a way to fix the problem? I have a nice Coleman 508 single burner that just loves to run, and I have never had a problem with it. I would like to have this 533 be just as useful along with the added ability to burn pump gas if the need ever arose
is the 533 new or did it have a previous owner? you can use a generator for the 442 stove, which has the needle coming out the jet (that's how these babies work) NOTE: According to Coleman, the 442 is DISCONTINUED - and so, yet another liquid fuel camping appliance fades into the dustbin of history! make sure everything is tight and hopefully not stripped - else you'll need some graphite tape the 533 works similarly to the 442 (same burner, generator, etc.) - at least mine do - YMMV
the 533 had a previous owner, but when i got it, it had Coleman fuel in the tank, and didnt look like it was used all that much. yep....another liquid stove dies.. it is getting worse everyday...
Don't dispair, try 'Old Coleman Parts', or something like that. Others, I'm sure, know the correct name. Also check e-Bay regularly. There are some generators up occasionally. Paul
442 and 533 use same generator. The 442 is gone but the 533 still sold new. Try and buy a generator for a 533. It sounds like generator problems
I'm with Geeves. My 533 burns like a rocket. Also you might pull the top off of the stove and look at the wadding they put in the little square box under the burner pan. It should be about half full front to back and full to the top of the box.
Yep, that cleaning needle should go from the valve control and on through the jet. Could it have broken off at the end? It also sounds like the generator is clogged full of carbon and not allowing the fuel to vaporize very well, so when you first start your stove, fuel just fills up the cubicle mixing chamber. It takes longer to get to blue flame and you get the occasional flare up too at the end of a burn. If there is fuel in the mixing chamber when you are done, the burner will continue to burn with yellow and small flames will come out of the mixing chamber. Time to get a new generator or the heat & quench process may work. You can try what is called a heat & quench on the generator to try and clear it. Basically, you heat the generator with a torch and then drop it in cold water. Once cooled, you blow out the broken down carbon with compressed air. Rinse and repeat. Not sure how successful you will be with the curved generator. Works great on straight ones that are on the double burners. sam
My first liquid stove was a 533. It did the same thing as yours. I sent it back, got another one. Did the same thing. It was me. The 533's need to be pumped up prety tight, not like a lantern or my 502. Pump it up high and mine works well, but it won't simmer at all. At low pressure, the manifold gets fuel in it and can burn down there. Before you get all crazy, try following the lighting instructions to the letter.
I clogged the generator on my 533 burning regular unleaded to heat water (for washing etc). It took several summers of regular use to clog it, so it was probably worth the fuel cost savings. I replaced the generator last year, and it runs great and simmers better than ever, so now I use it to cook and thus only burn Coleman fuel.
If your doing the heat/quench routine, pull the cleaning wire and remove the jet. This will allow the larger chunks to get out easier and you won't risk ruining the cleaning wire. If you have a compressor, heating it with a torch while blowing low pressure air through it will quickly get rid of nearly all the gunk inside. You will get smoke and/or yellow flames out of the end during the process. Once the crud quits smoking/burning, do a heat quench and blow it out with high pressure air and you should be in business.
