<<small enclosed porch that has a low ceiling.

Open window, cross ventilation, Ceiling Fan, a cheap one (life will not be
long kiln in a "Kiln Room") - do not mount directly over the kiln. The idea
is to keep mixing the hot air on the ceiling with cooler air from below. At
the same time bring in fresh air and exhaust Hot air that may contain nasty
things you would want to breath anyway.

The amount of "fresh" air required is VERY small. I have a friend who wante=
d
her kiln installed in a large walk-in pantry (6'x10' as I recall) with no
windows an no outside wall. We ran a short piece of 4" dryer vent from the
floor of the new kiln room, across the basement ceiling, to a old vent
opening to outside.

A 4" muffin fan was installed in the vent to bring fresh air in the floor
and a "exit" vent was opened in the ceiling with a 6" furnace vent that wen=
t
through the attic and out the roof. A salvaged 6" muffin fan was installed
in this pipe along with a used electric flu damper - this closes when the
power is turned off to the fans.

We took advantage of existing openings walls and in the ceiling, roof and
outside wall. Her kiln room does get much hotter than the rest of the house
but it is not overly hot. I built a simple alarm that will sound if the
positive ventilation ever stops and a smoke detector was added.

Apart from a kiln in the basement, this was the worst place I have seen for
one, but by carefully looking at the options we found a solution to all her
problems. Not all are perfect solutions since we were dealing with a 100
year old farmhouse.
