Hi everyone, This is my first post on this wonderful forum, but I've been browsing the old threads for quite some time now. I'm amazed how much passion the members put into their little stoves and, as a beginner in anything stove related, I would very much like to hear your opinions on the problem I have with my new stove. In short, I am the new owner of a Primus Omnilite Ti and I already ran into a number of problems during the trial runs. I have had it for about a week and it clogged twice. I used Primus Power Fuel and, after a couple of uses, the power diminished and eventually the stove stopped working. That happened twice and I had to clean the spindle and the tube in order to fix the problem. Today, I tried it for the first time with a gas cartridge. Everything worked great and, to my surprise, the stove was *a lot more powerful* on gas than on liquid fuel (I wonder if that's normal, too). However, my happiness was short-lived: after I finished cooking, I closed the shut-off valve hoping that the flame will extinguish. However, it went on almost unaffected (maybe there was a very slight decrease in output, but I can't be completely sure). In order to extinguish the flame, I had to close the spindle, as well. Would you consider this normal behaviour? It felt like the shut-off valve had no role whatsoever. May I ask what your thougts on the matter? Is there anything I can do / try? Many thanks and my apologies for my poor English, W.S.
@Winston Smith Your command of English is excellent! Regarding the blockages, I’m not sure if your stove is brand new or new to you, but either way it may be of benefit to flush neat liquid fuel through by removing the jet and opening the valves once you’ve pressurised the bottle. Outdoors of course and catch the fuel jettisoned in a glass jar. It may be that debris is visible in the fuel, maybe not, but the procedure should remove any lurking in the fuel line - if a new stove a residue of the manufacturing process is possible. Regarding the difference in output between liquid and lpg fuel, confirm you’ve been using the correct jet for each fuel. Otherwise, the extent to which you pressurise the fuel bottle can have a market influence on output. Finally, the time-lag between shutting off fuel at the pump valve and the flame going out at the burner (burner valve not shut) can be surprisingly long. The pressurised lpg remaining in the fuel line can take a good while to be consumed. John
Hi John, Thank you very much for sharing your thoughts. The stove is both brand new and new to me (my first liquid fuel stove). I can confirm that I used the correct jets (36 for gas cartridge and 32 for white gas). As for how I pressurized the fuel bottle, I filled it until the marking on the bottle and I pumped 20 strokes. Somehow, I suspect that the stove is not completely unclogged (although on gas it is scary powerful). I shall do as instructed on the following weekend (clean the fuel path by ejecting fuel with the jet removed). As for time lag, I shall give a try today and return with a follow-up. Many thanks, W.S.
Hi John and everyone else reading this, I can confirm that the shut-off valve functions well. I had never imagined that so much gas remained in the fuel path. My apologies for the silly question and many thanks for your help. Best, W.S.
If you look at your pump it says on and off position. With primus omnifuel or omnilite you flipp the bottle in off position to turn it of. After the flame extinguish you can close the valves or let the bottle de-pressurise. When the stove is hot dont close the simmer controll hard, when the stove cools of the simmer controll tend to get a bit stuck. I always leave it not fully closed with my omnifuel. Othetwise, nothing new under the sun. Primus stoves like omnifuel/lite are know for having residue from manufacturing causing the stoves to block up. I read about these problems all the time and I even sent primus a mail about it. Just give it a good clean and flush without spindle and jet mounted. Should solve your problems
I think so. For new stove, I use butane fuel as an inverted position more than 20min in order to clean the fuel line.
Hi. New to forum. I have a new Omnilite, and she continues to burn when I flip bottle over. I have to close the valve on the pump to stop the stove. Any ideas?
Sorry to waste your time. I flushed out system and she’s turning off when I flip bottle. Just needed to be patient. Thanks
I have an Omnilite Ti as well. Before I purchased it, I had read about issues with the stove clogging when new. Before I ever fired it I took the spindle apart and found metal shavings on the threads and some sort of heavy grease in the grooves on the tip. If you haven't removed the spindle and jet and flushed white gas through the internals to rinse out contaminants, I would. I could see any or all of what I found blocking the jet. Maybe the grease would have dissolved during use, but it may have taken a while.
Thank you. Yes. Like you I was worried by some of the post online, so I stripped mine right down. Couldn’t see any issues, but still had the usual clogging problems while running Kerosene. I particularly want to run kerosene because when I get to a hut at the end of the day, here in NZ the firewood always seems to be wet at the hut, and I need something extra to help get ihe fire going. So rather than carry firefighters I splash some kerosene on and that does the trick. But by mixing white spirits in with my kerosene and using the .36 jet, that should be gas only, it seems to be working fine, now I have resolved the pump issue. Thanks for the feedback.
