Hey Guys, Different question/problem with the peak 400A. Mine is from my Dad...probably mid-80's not used much till I got it last year. It was working great on a few trips, then it got dunked in a lake. I"m not sure if that caused the problem, but since then, when on there is a small amount of gas that bubbles up from the nut by the red leaver...its enough to catch fire if the wind blows the flame towards there. I've tried reducing the amount of fuel, reducing the amount of pressure, re-tightening the nut.....took it to REI to see what they could do. No luck. They recommended replacing that whole section, but it doesn't look like Coleman still makes replacement parts. Any other ideas/anyone else with a similar problem? I'm going on a Labor day trip, so I'm hoping to have it fixed by then.
Hello and Welcome!!!! Your problem is kinda a common and simple problem. Due more from age than the swim in the lake. Tightening the nut by the red lever should stop the leak. There should be 2 orings inside there that are starting to age and most likely should be replaced and is causing your leak Coleman doesn't offer that as a part but one can order a whole valve. If you are handy you can take the valve apart and replace the orings with new nitrile orings. The cleaning needle lever needs the same attention/oring too. I have a manual somewhere in my emails for the 400A. A great little stove. Cheers, Jeff
If its an oring then tightening past normal tightness wont help and may strip the thread. New orings is the only way. Take the inner section out and take it to a seal supplier. They can measure the oring and match to a new viton or nitrile one very cheaply. Viton is best but if they dont have it nitrile is ok
I recently bought a new valve + generator for my 400A, still to be found in the US, and I think Qvist in the Netherlands also has them (Qvist can be found in the "links" section). Would it not be possible to replace the O rings by graphite tape? Regards, Wim
There might be graphite in there. Some valves come with a oring and graphite. They are not user replaceable. Contact Coleman and ask for a new valve. Jeff
Hey all, I finally got around to taking the stove apart. I think there was some confusion about the nut that was leaking...it wasn't the tiny nut, but the larger one that attaches the generator system. In anycase, no o ring, but I did clean the system out, and the leaking seems to be reduced quite a bit, although not quite stopped. I think its reduced enough to take this weekend...we have a second stove in case it acts up. Thanks for the advice! I'll let you all know how it goes. This was my first stove taking apart/attempt to fix, so was pretty fun for me
If you run coleman fuel or any form of gasoline do not use if its leaking at all. The vapour will ignite and that will heat the joint which might seal it it but also might make the leak worse meaning more flame so more heat so more leak so bright flash and no hut or people in it. Not worth the risk
Hi, Q4, Geeves is absolutely, spot-in in his warnings about the very real possibility of a huge fireball, when using a leaking gasoline stove!!! I've experienced that, myself, only one time, and that was more than enough to convince me that it's not wise to take such chances. Kerosene is a much more forgiving fuel, in that regard, to gasoline. Don't take a chance, and best not use that Coleman 400 until you have stopped the leaking, completely, IMHO. Take care, and God Bless! Every Good Wish, Doc
