If you have more than one EnviroVent 2, you may connect them to a central duct. If a central duct is
used, hook the individual vent ducts to that central line. It is recommended that the central duct be located out-
side the kiln room if possible to maintain a vacuum system inside the room.
To determine what size of central ducting to install, use the chart below.
Number of Vents
1 2 3 4 5 6
Central Ducting Size 4” 6” 8” 8” 10” 10”
The duct 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 cover on the end of the discharge to prevent rain or snow
or small animals from entering the duct. 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.
Additional Considerations
• The EnviroVent 2 should not be directly hooked-up to another vent system that is a powered system - that
would create additional draw on the EnviroVent 2 system.
• If using a central duct system with multiple EnviroVent 2 blowers and all EnviroVent 2 blowers are not going
to be on at the same time (Due to one or more kilns not being used), then it is recommended to install air-tight
dampers on the output side of each of the EnviroVent 2 blowers. They should be closed when that blower/s
is not in use, in order to prevent fumes from re-entering the room via the kiln blower/s that are not turned
on.
• In order to maintain a vacuum system inside the room, it is recommended to locate the blower as close as
practical to the exterior of the room or the exterior discharge point.
• If mounting a blower up high, you may want to have the receptacle that the blower plugs into hooked-up to a
conveniently located wall switch for turning the blower on and off.

Ceiling mounting should be treated the same as wall mounting. It may be necessary to mount a receptacle high
on the wall to plug in the EnviroVent 2. Since the in-line switch on the cord will not be accessible in some instal-
lations, it may be necessary to also install a switch to control that outlet. Remember to turn the toggle switch on.
The EnviroLink may also be used to turn the fan on/off. See the Accessories section for more information.

On certain model kilns it is not possible to mount the vent cup under the kiln and it will be necessary to mount
the cup on the side of the kiln. In order to get the positive effects of Downdraft Ventilation, you will want to
mount it as low on the side of the kiln as possible. You will not need the plenum stand or plenum spring since
the plenum cup will be screwed into the side of the kiln. Don’t worry about the exposed hole at the bottom of the
cup.
To mount the cup you will need to drill 3 holes around the flange of the cup sized for the mounting screws you
are using. To find the size and number of holes to drill on the side and top of the kiln, find the closest chamber
size in the Vent Hole Chart and use those values. Once the cup is mounted the rest of the installation instructions
will be the same. Remember that it is always a good idea to consult with the Manufacturer of the kiln if it is a
brand other than Skutt.
