If this does not work - google to Jon Eakes and search for article in =
his database concerning improper venting etc.

Worth reading even if your kiln is not in the basement. MarjB

Venting is a critical problem in a home. Last year we had our gas
water heater replaced (22 years old) by a company that sells gas water
heaters. When the city inspecter came by to "inspect" the job he RED
TAGGED the water heater saying that there was no vent in the garage to
replace the air that was going up the 4" pipe that exhaused the burned gas
fumes out to the roof. Because of this the garage would create a negative
pressure and the carbonmonoxide would start to build up in the garage.

We had to instal a grated vent in the ceiling allowing fresh air into
the garage from the attic to replace the air going up the exhaust pipe from
the water heater.

Guess where my cerammic studio is??? IN THE SAME GARAGE. A year
before the water heater died I had replaced my broken garage door. I made
sure that the new door was insulated and sealed very well.

Isn't it "funny" how we sometimes go about improving things and in the
process may be killing ourselves. Sort of like the person getting small
shocks from his kiln and still using it.

Breathing better with better venting. MY 3 kilns are all vented to the
outside.

That's a good point. It is important to bring in fresh air to replace the
air vented from a kiln. This would be mainly for overhead hooded vent
systems.

interfere with furnace exhaust.

This was a problem when I built a home in MN in 1995. The homes were just
being built so tight that everyone on our street was having to buy something
called an "air exchanger". It was pretty commonplace there. We sold the house &
moved to CO just before we were going to buy one, but I know the prospective
new owners were already asking us whether they'd need one. I think this is
only a problem w/pretty new homes.

Hello,

Venting is very important for our health, but if you don't have a
(good and sensitive) carbon monoxide detector in your garage/studio,
and another in your adjacent living space, I'd strongly suggest you
get them to be safe.

Others on clayart have recommended a battery-operated model sold at
for $100. You can search the clayart
archives for "CO detector" to read why it's important.

Regards,
Maurice
