Replacing the kiln on the stand
Place the EnviroVent

unit on your kiln stand as
shown in the photo. The kiln stand must be 8” high.
Tilt the stand at an angle to avoid forcing the vent
tube through the opening. There must be air space
between the motor and floor.
If your kiln stand is not 8” high, obtain a new one or
use non-combustible supports to elevate the stand.
The use of shim blocks is acceptable provided the
kiln remains stable and level.

Type and Length of ducting
A flexible 4” aluminum dryer ducting is recommended for installation No more than four
90

bends may be used without reducing air flow in the venting system or reducing draw
into the kiln. Distances beyond 60 feet or installations with more than four 90

bends need a
transition to 6” ducting no farther than 20 feet from the plenum. It is possible to transition
directly from the plenum.
Selecting and Installing the Ducting
If you have more than one EnviroVent

, you may install them individually or connect each
unit to a central duct to remove the gases. If a central duct is used, hook the individual vent
ducts to that central line.
To determine what size of central ducting to install, use the chart below. A “Y” adapter can
connect two kiln ventilation systems together. However, a damper should be installed in
each duct line and left closed when the ventilation system is not in use. This prevents a
“back flow” of fumes into the unused ducts.

Discharge may be horizontal or vertical with the exit located a minimum of four feet from
any opening (window or door) into the building. Provide a shield to prevent rain or snow or
small animals from entering the ducting exit. For horizontal discharge, a flapper or hood
type dryer exhaust vent may be used. For vertical discharge, a cap type shield that does not
reduce the discharge may be used.
