I think the Petromaxes are too complicated and thus a little bit unreliable for torch fishing (in Finnish tuulastus) in a moving small rowboat?

Better to use some very bright halogen (as a car flood light) or led lamp with a rechargeable battery.

Yes, the main differences are that HK500 is much bigger in size and also the light output. Petromax say that HK150 will output some 100W and HK500 some 400W compared to an old incandescent lamp bulb.

When I pump my HK500 to the red mark in manometer it will burn at least for 6 hours without pumping.

The light from HK500 is very bright and and it is not pleasant to watch it straight. Therefore I use in my HK500 a side reflector (s5) and also now and then a top reflector (top5c).

In my HK500 I had the same problem with "top burning", very big flames coming out from the upper part of the lamp.

The reason was a much too large mixing tube gap. When I adjusted the gap using the toolset (66-180) I got rid of the top flames.

Thanks for the tank cleaning advice, i will do that.

One more thing: Earlier i told that I am using the ceramic clay burner. But now when I investigated it, I noticed that it was the metallic one! Now I have replaced it with a spare ceramic burner, but I must first clean the tank before I again try to ignite the lamp.

Hi again,

I tried the watertest after I had emptied the tank of kerosine. I pumped the pressure to some 2 atm and there was no bigger leakages, only some bubbles from the manometer. The manometer dial was filled with water during my testing and then the bubbling stopped. Is this normal, or should the manometer be replaced?

When i emptied the tank, I found that there where very much brown dregs (sediment) in the tank. Is it possible to clean up the tank by washing with water?

One more question: Because my lamp only leaks kerosine when it is burning, is it possible that there will be somewhere a leakage due to thermal expansion of some part?

Best regards

hi Keneth,
did you remove the old lead washer coplete before remounting the new lead washer, becuse you should have to do this every time when changing the lead washer.

Yes, I remowed the old lead washer, it was quite deformed.

please ckeck if the nozzle spray vertical upside, but be careful and catch the outgoing gasoline with a towel or tissue:
Mischrohrglühen, schon alles versucht..

Hi,

Yes I think my mantle is too high up, i have fixed it to the first ledge of the burner! The burner is ceramic, not metallic.

I shall also soon try the underwater test and bigger mantles. The airflow I have already checked and it is ok.

Thanks for advice
Kenneth

That looks lite a mantle for a 150hk lamp. The 500hk mantle is much bigger than the burner.

The mantel in the picture is a Colemann Goldtop 1111. And on the packages it says that it is for 500 CP.

Hi, many thanks for the advice!

I will try to find the leakage by the water test. I fastened the generator to the lead seal very tight when i renewed the seal.

Will also try to add the brass gaze (from Pelam shop) to the upper part of generator.

I have normally used Luxor 400/600 CP, Pelam 500-600 CP/HK or Coleman Gold Top 1111 mantles.

I linked to a picture of the mantle (Coleman) after my lamp has burned some time:

Hi,

I have a
Petromax 829 500CP that I have not used for a couple of years. I now have renewed almost all seals and also many other parts, as the generator needle. The lamp isnow burning ok, but there are still a few problems:

- The generator is leaking kerosene from its lower part I think. This happen only when the lamp is burning. When it is pressurized but not burning there is no kerosene leakage. Could the fault be in the lead washer (also renewed
this)?

- When the lamp is burning it has a somewhat pulsating noise (once a half second) and also the light intensity is slightly pulsating. Is this normal?

- After every burning of my lamp I have to change the mantle because there has become some holes in the top of the mantle. Is this normal?

- What are the best mantles for Petromax 829 Rapid 500CP?

Many thanks
in advance for answers to my many questions!

Best
