New to this-think my first attempt got lost. Like to talk to anyone with
actual experience and hopefully some success with the four burner Propane
conversion kit from Summit kilns in Florida. I've fired mine 4 or 5 times-
biggest problem is temp difference from top to bottom- cold on top (cone 8)
and almost too hot on the bottom (cone 11) I added an extra lid and switched
the bottom shelf from round to octagonal- little or no difference. Read some
stuff about temporary flues etc. would like to hear more Thanks.

Jim - Post back with some more specific information about the kiln, flue
opening size, shelf arrangement, gas pressure and anything else you may have
changed each firing to try to even it out.
We did a conversion a few years back at school, but then got busy with other
things and finally raised the funds for a larger gas fired kiln and
building, so have never fired the converted kiln... I do remember some
reservations about the appearance of the burners, no primary air adjustments
and cheap pipe burners.
But, I've been firing an Olympic updraft at my own studio that I've done
some renovating to and though I fire to ^6, I've been able to achieve some
very even firings.
Most folks have problems with the top too hot, so I'd be interested in your
issue of hotter on the bottom. Sounds like the flue being too small or being
restricted/closed off too much.
