Wayne,
Properly installed, a vent such as you mention for an electric kiln
should not significantly affect the firing schedule. Mine certainly has
not.
As you mention, the volume of air pulled through the kiln is low IF the
vent is installed properly. The idea is that a candle flame held to a peep
hole of the kiln should be gently pulled into the peep by the effect of the
vent. Most of the air moved by the vent fan is pulled from the room and
serves to cool the small volume of hot gas being pulled out of the kiln
itself. At least that's how my Bailey kiln vent works.
Good potting!

If a kiln vent sucks air from inside the kiln,
and exhausts it, how does that affect the heating of the kiln? Does it
considerably slow a firing (I'm thinking electric kilns here, not propane
or gas) or is the cubic feet of air exchanged low enough where the heat loss
is not enough of a factor to consider?
