I found a old Hipolito stove in my mothers old camping equipment and have been trying to get it to work, using what I think is paraffin. I preheat using alcohol and then after a few moment put some pressure on the tank but nothing happened. There was no manual included in the set but I found a video online that uses the same method on a comparable stove which seemed to work beautifully. I would like to know if there are steps that I need to perform on a stove that hasn't seen any use in over 20 years. To help it back to life. Any help would be greatly appreciated. (I tried to find a topic covering this topic but couldn't find any in the time I was prepared to spend looking...and sorry for any mistakes in my grammar/spelling, Dutch guy here)
See if it will build up pressure by screwing in the air vent screw and the fill cap and the travel cap in the burner hole pump a few times. Then open the air vent to se if air escapes. If not then grease or replace the pump leather. To find an air leak you can pump a little pressure into the tank and put it in a bowl of water to see where and replace the seal or see if there is a crack somewhere. Also check the nipple/jet in the burner with the cleaning needles to see if it's blocked. Btw, the travel cap screws onto the pump knob when the burner is mounted so you do not loose it. Also the wind shield is upside down in the picture =)
Thanks for the fast reply Eamonn. Submerging the stove in water after giving the pump a few goes, doesn't show any leaks. But it would seem that there is no pressure buildup from working the pump; no hiss when turning the "air screw". There is some resistance while pumping though, and the pump leather although old doesn't seem to bad it isn't hardened. |imgRemoved|
Hi Andrew, Welkom! Good to have a fellow countryman on the forum. You've probably found how this type of stove works: Preheat and pump. Here's a good article about general principles & operation of pressure stoves: https://classiccampstoves.com/threads/90 From your description it seems that fuel does not come out of the burner. The most likely cause is that the pump is not working (thus the stove does not build pressure). Have you checked the pump? If not, then the first action should be to oil the pump leather and make sure that the pump builds pressure. Steps: 1) Soak the pump leather in oil. 2) Spread the leather a bit, so that it touches the inner pump tube well (and it builds pressure when pumping) 3) Then see if the stove builds pressure when pumping. Fuel should be coming out of the burner jet. Any oil can be used (although mineral oils are best); for instance WD40, motor oil or cooking oil. A word of warning: Do not use gasoline (NL: benzine), but kerosene/paraffin (NL: Petroleum). Benzine is too dangerous to use in a stove like this. Thnx for your update! Peter
Welcome to CCS. To pressurize without pumping you can submerge the stove, preferably empty, in hot water. The hot water will build pressure in the tank. You should get air bubbles from the jet/nipple. You can take the pump tube out if you would like because if the NRV leaks you will see bubbles from the pump tube. If so a PIP for the NRV, or a replacement NRV, is needed. If the fuel filler cap leaks a new gasket is needed. Gaskets are available from The Fettlebox. See the link on the right side of this page.

Thanks for the suggestion Peter, I have now treated the pump leather with WD40 but will not continue with the stove tonight. Thanks for the link to the "howto", that was what I was looking for to begin with, as the stove no longer has a manual. Thins is what I was using as fuel, meant for classic whick lamps: |imgRemoved| The guy at the outdoor stire (beversport) I visited looked at me puzzled when I asked him for paraffin oil, he sent me to a hardware store where I got a very similar look.
Hoi Andrew, welkom aan boord! You have oiled the pumpleather, great! Now you must be able to get some decent pressure into the fount. If this is not so (a lot of back-pressure on the pump but no air in the fount) it means your non-return valve (aka NRV) is stuck! This can be overcome by pouring some fuel in the pumptube (half full is ok), replace piston and aply pressure. This should make the NRV "pop". If not so, you'll have to undo the darned thing. It sits at the bottom of the pump tube. This takes a special tool, if you need it we'll give you the dimensions to make your own! This tool is also needed when the NRV leaks pressure & fuel into the pump tube. Over all, you have a very fine looking stove, in what must be the most practical size for camping with 1 to 3 people. The fuel you bought should do the trick, but is way to expensive! Slightly cheaper are the 20liter drums for heaters like Zibro kamin etc. Cheaper still is trying to locate someone that sells petroleum from the pump! Less than a € per liter! Anyhow, let us know how you get on, never hesitate to ask questions (remember, there are no silly questions, only silly/stupid answers!). Groetjes, Wim
That's the stuff. Some grill lighting fluids are the same thing. Don't use it if it can be lit by a match. I buy paraffin/kerosene at petrol stations or in the chemical lockers at well stocked supermarkets. Funny about names, paraffin oil here is food grade mineral oil used for treating cutting boards.
lamp oil might be the right stuff but it might also be too thick with to high a boiling point. Even so it should light although not well. I have some lamp oil here I tried and the stove lit but very yellow and spitting little fireballs everywhere
Hi Andrew, Very nice complete stove. You should have it working well in short order. Pretty much any oil will work for the pump, but WD40 is very low on the list; probably no damage done but it contains volatile solvents and will just dry out again. Better to use something heavier like clean motor oil (non-detergent if you have it) or clear mineral oil (food grade/pharmaceutical stuff). You want the leather well saturated -- just put the whole pump rod with leather cup into a small can or jar with about a centimeter of oil in the bottom for a few hours or overnight.
I am a little concerned that you are using the correct fuel. In Australia it is Kerosene or "Kero." I agree with Geeves that your fuel may or may not work. In Australia, Lamp Oil is more viscose than Kerosene. Here is a link to the table of international fuel names: http://fuel.papo-art.com/#tableoffuelnames Can I suggest you reread Dutch Peter's and Wim's post and make sure you have the correct fuel. Norm
Thanks for all the comments guys, haven't had time today to do anything with the stove. I'll put the pump leather in some other oil and try Wim's trick for the valve, because I do believe that that is where the problem is. I'll also look into the fuel, is diesel perhaps a good fuel?
After some cursory research I found the the fuel I started with (the bottle in the picture) should have a boiling point between about 170 and 320. That sounds about right, right?
Hi Andrew, About the fuels: The difference between fuels can be a very confusing subject, although very interesting and a good read. For instance http://en.wikipedia.org/wiki/Fractional_distillation or http://en.wikipedia.org/wiki/Kerosene The lamp oil will work in your stove, although it is a bit too heavy. That is, the burner does not generate enough heat to vaporise the heaviest hydrocarbons in lamp oil. As a result, the stove will burn dirty with smell and sooth. That sooth will block the burner in the long run. I think that the lamp oil is good enough for testing and getting it running, but you would want real "Petroleum" (EN: Kerosene) for cooking! The best "Petroleum" (Kerosene) for stoves should have only the lighter fractions, with a boiling point far below 330. Then the burner will be able to vaporise all the Petroleum and, as a result, the stove will burn clean. Best is to get proper "Petroleum". It's sold at hardware stores (NL: De bouwmarkt) for about 5 Euro per bottle or 35 Euro for a Jerrycan. The "SEL Gezuiverde Petroleum" is very pure, very good, not expensive and can be bought from olielamp.nl. Problem is the shipping costs; you have to buy in bulk to compensate for shipping .. A cheap option and easy option is the "Grill lighter fluid" as sold in some supermarkets (Jumbo, AH). From the label it has the same content as the "Gezuiverde Petroleum" and is also manufactured by SEL. Again, please do not use gasoline (NL: benzine, wasbenzine) as this is too dangerous. So, I hope this information is of help and I'm looking forward for more updates in this thread The best update would be a flame shot of the Hipolito Cheers, Peter
That was a good suggestion Peter, I bought the bbq lighter fuel which work like a charm. The other important suggestion was the one from Wim, pouring some fuel in the pump and then pushing with the piston gave a clear noise from the tank, where there first was none. I wouldn't call it a pop but I guess it was close enough. You can't really see the flame but I guarantee you it's there, roaring beautifully : |imgRemoved| Now I only have to find a useful little squirt bottle in which to put the ethanol for lighting. Thanks for all the help people...I didn't think it would be this easy. I can remember that using the primus always was a pain. But now having used it I can't really imagine why that was. It's not a s easy as a butane stove but I guess it shouldn't be...
congrats! i remember the first time i fired up a kero stove - it was a great feeling - hope you have lots of good times with your stove - it is a special item! willie on the kero burnin' Gulf of Mexico
