Hi!
Petromax recommend their Alkan product as fuel:
http://www.petromax.de/website…images_zubehoer/Alkan.jpg.
However, I cannot find the actual components of this fuel on the site - just the picture!
Types of fuel which can be used with the Petromax HK 500 range widely from jet oil to diesel, even gasoline or petrol (whichever name is used for the stuff which cars run on and isn't diesel).
I assume Alkan is a purified kerosene or paraffin. Does anyone know (1)?
This vegetable or "bio" product from Denmark is quite new:
XXX (there is also an outdoor variant).
However, even Agowa cannot tell me if it works in pressure lamps. They "think" it "probably" can. Not impressive.
However, the lack of fumes from the oil may mean the HK500 can be used indoors, if the oil works. Has anyone tried it (2)? I will be getting some for ordinary hurricane lamps, but will be starting my new HK500 with Alkan (as this product presumably cannot backfire). I will then maybe briefly try the Agowa product, to see what happens.
I bought my HK500 from XXX who, when asked, stated the HK500 should not be used indoors because of "dangerous fumes". Does anyone know what is being talked about here: carbon monoxide or explosive gases (3)? Both (3)? I note Tilley lamps are advertised as being used indoors at home:
XXX
There seems to be a contradiction here!
Any answers to or clues arising from my three questions, (1), (2) and (3) above, would be greatly enjoyed.
