There are potters that may be new to using propane and there are always =
questions about pressure regulators. I have found using a large volume =
regulator directly off the tank, going to =BE" pipe works well. The =
smaller regulator used to control gas to the burners is usually a 0-5 =
pound regulator or a low pressure gauge. =20

The gauge I found and have used for years is a Fisher FS 627-6210, type =
627, 5 -20 pounds and has a =BD" orfice in the regulator. I use =BE" =
pipe that runs to a large 2" pipe that runs the length of the kiln =
area. Using it this way you can operate several kilns at the same time, =
both low and high pressure as the regulator allows for large amounts of =
gas to flow to several kilns. I have the same regulator on a single =
kiln using s burners and the kiln fires like a dream. I have a single =
inlet to the burners and open the petcock and adjust all the burners =
with one regulator. The pipe surrounds the kiln so each burner has the =
same pressure. I have over 500 firings on this kiln and it just keeps =
on going. The secondary regulator is Fisher 0-5 pound regulator. The =
only problem with the large regulator is the cost, but worth every =
penny. The large regulator has adjustable pressure also. I have =
turned on the burners and adjusted the volume of gas and you can finely =
tune the burners, I am using Pyronics 80 ET medium pressure burners.

I was going through my paper work and thought I'd send out the regulator =
info for good measure.=20

I'm working in the studio, waiting to go to a Blues concert. Roy Rogers =
is a great slide guitar player. I'm listening to Ray Willie Hubbard now =
and if you like Texas style blues you'd like him.=20

I know I'm off the subject of pots......
