I had the same problem and discovered that the kiln was built as a natural
gas kiln. It had the wrong orifice in it's burners. One way to check for
this is if it fires with with large yellow flames. Also check the kiln name
plate because the plate will say which gas type it is built to use.

Also some back pressure is needed so a broken shelf can be used to
partially block the opening on the top of the kiln.

If it is the orifice that needs to be replaced it is easy to do. A call to
Olympic will be answered by a very helpful person who has seen this
problem before. The burners are easy to screw off the manifold and they
come apart with ease. Replace orifices and put it back together. NG orifice
is larger than propane orifice so way more gas is trying to burn then the
burners are capable of efficient use so they burn dirty and cooler.

Good luck,
John McClure
