On kilns over 12 cubic feet, and up to 24 cubic feet, you will need a Dual Intake Kit to vent the chamber using two
plenum cups. This is to ensure the proper amount of air is vented without overheating the ducting. For oval
kilns use the charts and diagrams below to drill the proper holes in the lid and slab. If the kiln is over 12 Cu. Ft,
follow the instructions for installing an Envirovent 2 with a Dual Intake Kit.
For other kilns between 12 and 24 cubic feet contact the manufacturer before installing the Envirovent 2.

An 8 ft. length of flexible 3” diameter, aluminum ducting is supplied with your kit for installation. If the distance
from your kiln to the vent hole in the wall is greater than 2 ft. you may need additional ducting. This depends on
how high up the wall you are ducting and how much stretch you can get from your 3” flexible ducting.
When additional ducting is required you have several options.
Option 1
You may purchase one or more 8 ft. extension kits from Skutt or a Skutt Distributor. The kit comes with one 8 ft.
length of 3” flexible ducting, one 3” coupler, and two hose clamps. If you are going to vent the kiln further than
60 ft. or have 4 or more 90 degree bends, you will need to transition to 4” ducting no further than 8 ft. from the
plenum cup.
If it is necessary to step up to 4” ducting, we recommend you use PVC since it will not corrode and is relatively
inexpensive. A transition piece from 3” to 4” may be difficult to locate but is available through Skutt along with
the transition piece needed to go from the 4” PVC back down to the 3” motor mount. See the Accessories Section
for more details.
Option 2
If you prefer, you can transition directly from the 3” ducting to 4” PVC. Remember that you will need to pur-
chase the transition pieces from Skutt.
