I'm at 5,400' altitude.
I have both chimneys on my two Aladdin lamps: one short, one long. Maybe it's just me, but I don't see that much difference between the two. But I've not yet used them very much, so could be I'm new to this learning curve.
You can buy the high-altitude extension from Lehman's Hardware online.
But being cheap, I made an extension from a piece of handy coil.
- Make the right diameter chimney jig. Cut several TP rolls lengthwise. (TP rolls are 4" long, about the length of the extension adapter.) Wrap/tape each around an uncut TP roll until combination is the diameter of my shorter (cheaper) chimney. (Took maybe 3-4 TP rolls to build up to correct chimney diameter.)
Cut a piece of handy coil 4"x7.5". Wrap handy coil around chimney jig: the ends will overlay ~.5". Tape handy coil tightly in place. Drill three holes along coil overlap and through chimney jig: you won't hurt it. Un-tape handy coil, remove chimney jig.
Remove tape residue. Secure coil with pop rivets through drilled holes.
Add two additional pop rivets (equally spaced ) opposite one of the end pop rivets. Those three pop rivets become the legs which allow the chimney extension to sit on top of the glass chimney.
In use the handy coil extension will turn dark.
In use, I can't really see much difference between using the lamp with/without the extension.
It is possible I should have made the extension a tighter/friction fit as there is a small gap between it and the glass chimney. So maybe too much air is leaking past and the lamp is not seeing enough additional vacuum to make it work better.
But even without the extension, the shorter chimney Aladdin is still bright, so plan to use it that way and not bother with the extension.
Just for grins, tried the handy coil extension on my flat-wick lamp to see if it would work better (chimney top diameter was comparable). Didn't see that much difference in brightness, but the flame was acting differently (maybe taller, more feathery edges; but it's been a while and I've forgotten), so more air was flowing through the lamp.
Bottom line. Will probably just use both lamps (Aladdin and flat wick) without the extension; and buy the shorter, cheaper Aladdin chimney as replacement.
