Loading the Kiln
The bottom kiln shelf needs to be supported at least one inch off the kiln floor to
allow sufficient air circulation. If the holes are blocked, venting cannot take place. If you are
using half shelves, a slight gap left between them will allow better air circulation in the kiln
chamber. If you are loading ware near the lid be sure not to place it directly under a vent
hole. This may cause discoloration in glazes or thermal shocking.
Be sure to close the lid and plug all of the peep holes. You can open any peephole during
the firing to check the bending of witness cones and the progress of your firing. Do not
prop the lid or leave any peepholes open during a normal firing. To do so can cause fumes
to enter the room and additional room temperature air drawn into the kiln may affect the
firing.
Important: Keep the kiln floor clean and the holes unobstructed for the
EnviroVent 2 to continue doing its job properly.
Motor Operation
The EnviroVent 2 motor is equipped with an in-line toggle switch in the power cord.
This switch must be turned ON in order to ventilate your kiln and collect the fumes.
Leaving the motor in the on position during cooling will reduce the amount of time it takes
to cool the kiln to a temperature where you can safely handle your ware. Turning the mo-
tor off will not significantly affect the kilns ability to maintain temperature or perform a slow
cooling therefore it is not necessary. If you would like to be able to automatically control
when the Envirovent 2 turns on and off, you can install an EnviroLink on KilnMaster and
GlassMaster Kilns. See the Accessories section for more details.
Fresh Make-up Air
It is essential to have a source of fresh air to replace the air vented outdoors. The
EnviroVent 2 fan moves 140 cubic feet per minute. Unless you know that the room ventila-
tion can handle the total volume of loss, leave a window or door slightly ajar for make-up air.
Remember: do not exhaust fumes near a fresh air intake.
Firing times
When the correct holes are drilled in your kiln, firing times should not be much longer
than normal. If firing times are significantly longer, see the Troubleshooting section for help.
