rEparation
• Unplug the kiln
• At the time of purchase it is possible to order the kiln factory drilled. If your kiln has already been drilled for
the EnviroVent 2 by Skutt, you may skip to Step 6.
• Before drilling the holes in the kiln it will be necessary to empty all of the ware and shelving from the cham-
ber.
• Nearly every Skutt kiln uses a 8” high stand. The EnviroVent 2 is designed to fit under this 8” stand. If your
stand is lower you can either shim the legs until it is 8” off the ground or replace it with a correctly sized Skutt
Stand. If your stand is higher than 8” you can shim the plenum cup up so the bottom of the base is 8” from
the bottom of the kiln or replace the stand with one with 8” clearance.
• If your kiln has been previously drilled for an EnviroVent or any vent other than an EnviroVent 2, it will be
necessary to patch the existing holes before drilling new ones. Failing to patch incorrect holes in the kiln
floor could cause the vent not to perform as designed. It is usually not necessary to patch holes in the lid
unless they are drilled further than an inch away from the kiln wall. The amount of air vented is regulated by
the holes in the floor so additional holes in the lid will not affect performance but could affect your ability to
test the vent. See the Testing section of this manual. If you find that you need to patch holes in the lid follow
the instructions below.
Patching Existing Holes
• Disassemble the kiln to allow full access to the kiln floor. (This will need to be done to remove an existing
EnviroVent anyhow).
• Cover one end of the openings to existing holes with tape.
• Use Skutt Sairset (part# 0290) to fill the holes through the uncovered opening. Use a paper clip or element pin
to help fill the hole. When you can’t get any more in the hole use a spackling knife to clean up the excess ce-
ment.
• Turn the kiln floor over, remove the tape, and fill any voids with Sairset.
• Re-assemble the kiln and allow the patch to dry for 1 hour before turning on the vent.

Use the Vent Hole Chart and Location Diagrams to determine the number, size and location of the holes for your
particular kiln. The chart and diagrams are based on standard multi-sided top loading electric kilns greater than
1 cubic feet in size. If you are planning on venting a kiln smaller than 1.1 cubic feet please contact Skutt for hole
drilling instructions.
The Vent Hole Chart refers to the number of “sides” a kiln has to determine the chamber width. This number
refers to the number of brick used to form the circumference in a round or oval shaped kiln. This measurement is
fairly standard between brands. Some kilns with 3” brick have smaller diameters but will not change the number
or size of the holes drilled.
Kilns that are square or rectangular with multiple bricks per side will not fit this rule. For these kilns find out the
total cubic feet of the kiln and use the closest value in the chart.
