I had a heat detector in a kiln room and the same thing happened anyway...It
went off 10 minutes after I left school that evening. The fire trucks and
everyone came rolling in and I heard about it the next day. They also had to
replace the heat detector the next day...I think they are only good for one

If they install a heat detector by your kiln be sure they do not to it directly,
or even diagonally, above the kiln. I had BRAND NEW classroom (2 years old)
with ventilation and kiln room built into the plans. It was not fool proof
either. However, a heat detector would most likely be better.

The part I found ironic is that after the detector went off they wanted my to
prop my door to the kiln room open while I was firing so the heat would not
build up in the room. I thought the whole purpose of having a door that shut
automatically to the kiln room was to keep both fire and fumes in the room.
There was a larger hood for the fan sitting in the closet for 2 1/2 years that
they kept saying they would put on...wouldnt it have made more sense to put the
proper hood on so the ventilation would work better? Oh well....

Good luck.
