The Orton KilnVent very efficiently removes fumes from the kiln room by pulling just enough air from the kiln to create negative pressure. This prevents fumes from leaking out of the kiln. On most kilns the vent is positioned between the bottom of the kiln and the kiln stand.
The Orton KilnVent is very effective at removing firing odors. But if you can still detect an odor during KilnVent operation, check the following:
1) Make sure you can hear the fan spinning. This is basic but easy to overlook in a busy studio.
2) The holes that draw air out of the kiln must be free of obstructions. If the exit air holes are in the bottom of your kiln, the bottom shelf should be positioned 1” above the kiln floor. The shelf must not close the holes.
3) The intake and exit vent holes must be of the correct number, size, and location in your kiln. See the Orton KilnVent instruction manual to be sure, or call Orton: 614-895-2663.
4) Insert all the peephole plugs. Leave the lid fully closed.
5) Check the vent duct for leaks.
6) Make sure the duct is free of obstructions and that the vent flapper on the outside of the building can open freely.
7) If you fire ware that contains many impurities, you may need to fire smaller loads.
