Okay.

So I adjusted the rods, changed the jet (I think the apature was wrong (crap Anchor one, I wonter if Pmax will fit and is better quality?),crushed one needle and got one that worked.

This time I started the lamp and it lit properly.

I noticed a lot of heat at the tap.

Half frosted glass, I looked under and saw a hole straight through the bottom of the mantle, and a rocket jet blowing down.

Other than that the mantle was burning well, but I don't know how it would have looked without that hole.

I turned it off and worried for my glass.

The tap didn't shut it off this time, I had to release pressure, but it was very hot, so maybe rod adjustment is still ok.

I am waiting for it to cool to try another mantle.

I wonder if this is just a rubbish brand mantle? It comes from German place that makes Anchor globes.

I will try one more of these, then if that blows I have only one Coleman mantle I will try that.

I think that only the jet (nipple) controls the pressure?

My last resort will be to send for another jet and see if that fixes it. Do you think a Pmax jet will fit the Anchor vaporiser?

Now I got my parts, so I fitted them and started to heat the lamp.

To my surprise, the fuel started flowing when the vapouriser got hot.

I think the rod must have expanded and opened the valve, so I will adjust it.

Also when it was running it seemed like too much fuel was coming, the flames came right through the mantle.

I will adjust the height of the mixing tube and see if it makes a difference.

For some pictues (because the text is in german) you can also look in Petrowikia --> LINK

Thanks for that.

One difference between the Anchor and petromax may be that when the Anchor manometer is fitted tightly it rests upside down.

How stupid is that?

Zitat von Andreas Finke

I think, it's because the two valves and the pumptube. If You use the normal pump, the pressure is high enough to open the valve. When You use the pumpadapter, the pressure must at first fill the pumptube and then it must be high enough to open the bottomvalve against the pressure of the metallfeather in the valve and against the pressure in the tank.

I think you are right.

Other people don't report a problem but maybe they use a foot pump and maybe it puts more pressure. I will have to try it.

I didn't do the butane test but the standard pump works well so I think the manometer is ok.

Thanks for the reply.

I just checked the seal, it looked fine, unlike the fuel valve which the seal kept popping out of, until I put a little nick in the edge of the housing to keep it in.

(I have to point out that I have read users on this forum that had this same problem with the Petromax also from new).

I have a feeling that the check valve may be getting stuck on some burr on the air exit holes in the valve body when there is pressure in the tank. these holes seem to be smaller than on the Petromax. I may strip the valve again and try some sandpaper in there. I could also try and sand the valve piston.

I am hoping that after it has been used a bit it will work easier.

I'm still waiting for parts before I can use it. The parts I ordered came and when I went to fit them the burner fell ti bits.

I still cannot explain why the standard pump will push air through wheras the bicycle pump won't.

I haven't tried it on a compressor airline yet.

I know there is a difference between Petromax and its clones but I don't think it is as terrible as the difference between a BMW and a Chang Jiang.

I looked to find mention of people complaining about Anchor being rubbish and I never found it.

This lamp has cost money due to damage from not working properly to begin with, but I think the same could have happened with a Petromax.

Any comparisons you can make between the two would be appreciated.

I got an Anchor 500CP and from new it seemed to take forever to get any pressure in it and would not go past the red mark.

So I got an EZ pump.

The check valve would not let any pressure in through the EZ pump.

I diisassembled the check valve, nothing wrong and refitted it.

This time I can hear the air going into the tank when I pump, but it stops at manometer reading 1.

I let some pressure out and try again, and two more times the valve works up until pressure "1".

Now I refitted the normal pump and the thing pumps up easier than ever, and to full pressure, and I can hear air going into the tank with each stroke.

So I refit the EZ pump and try again, and the check valve doesn't operate.

I put back the standard pump and again it works fine.

How can this possibly occur?

Thank you. I also would like one of these oxy burners.

I will leave the stainless one now, thanks to your advice.

They need to produce a mixing tube/mixing chamber/burner all from stainless and then maybe the problem would be solved.

Why is the stainless one crap?
I was just going to buy one of those.

Why is the "oxy ceramic" one so good?

Thank you Frank, that gives me confidence now that if I fit them that way they will be ok.

The lamp cost me £40 and I am about to spend £52 on parts!

But I have seen it running well, and it will be well worth the cost when sorted I'm sure.

Thanks.

When I got my Anchor 500CP recently I had to strip it almost immediately and when I reassembled the needle and jet, I did so with the needle in the raised position.

Once the lamp had been run, when I raised the needle it did not come through the hole but it crushed.

The same thing happened with a replacement needle.

When I fitted the last needle, I put it in the lowered position before fitting the jet and now it goes up and down fine.

Has anybody else come across this problem?

Hello everybody.

I have an Anchor 500CP that never worked properly from the beginning.

It was great for the time it burned properly, but the rubber from the tank valve kept coming unseated.

I solved that by putting a nick in the edge of its housing, but the top had overheated and the air screw fused, and then the mantle sooted up and broke so I turned it off, but the globe broke on cooldown.

Now I think I can sort it out and improve it by using some petromax parts.

I read here already that the thread on the mixing tube is different, but if I use Petromax mixing chamber and nozzle then that is not an issue.

I would be extremely grateful if anyone can confirm the compatability of the following parts with my Anchor 500 CP:

Mixing tube.

Globe.

Mantle support.

Pump piston (O-ring).

EZ pump fitting.

Needle.

Thanks in advance for any help.
