For a stack, we used a galvanized metal culvert, 12" dia, about 16
feet tall. The stack goes well above the roof's peak... The gable roof of
the shed utilizes metal roofing which can be purchase or ordered through
any lumber yard... Frame out (head out) your roof rafters, ridge poles,
ceiling joists, etc.. so that the stack clears those wooden structures by
10" or more... In addition to the above, you can also use sheet rock to
construct fire wall barriers (sheet rock spacers plus sheet rock) along
these wooden members that are in close proximity to the stack... You must
obviously use something like tin snips in order to cut the metal roofing to
provide a space for the stack to pass through the roof's peak. I used
guide wires on turn-buckles to help secure the stack...
If your kiln is inside a closed-in building then fire codes most
probably requires that the stack has to be constructed with hardbrick
instead of galvanized metal culvert...
Why go to all this trouble... once you do a glaze fire in a gas
kiln in a reduction atmosphere you will see and understand... not to
mention the econony of firing propane, both bisque and glaze, in contrast
to the expense of electricity... Marshall

Hi Dave,
I have been firing reduction outside with propane with an unprotected no shed
kiln since 1972, but now that I am moving about 13 miles t o s new site I
wanted some weather protection for it.In the past a transits sheet covered a
single arch covered with a blanket of fiber.I will be able t o get a natural
gas line at my new site but need to make certain that i get consistant
pressure and not some high "commercial" rate.I have been informed that
natural gas will be cheaper. The roof thing I am trying to figure out is
whether a hole lined or protected or a two level roof design of sorts was
best.Our weather is ungodly hot in August and i was trying to make certain
the hear wasn't trapped under the canopy. Thank you very much for your
help.It is going to the 60's here today.
