Kiln Vent and Kiln Hoods
by L&L Kilns
WALL MOUNTED VENT BLOWER
The vent blower motor is mounted on the wall. This keeps the heat of
the kiln away from the motor (for long motor life) and keeps the motor
vibration away from the kiln (which can cause ware to move, damage to
the kiln, and misfiring of cones on a Dawson Kiln Sitter).
VACUUM IS SAFER THAN PRESSURE
The vent tubing is kept under vacuum instead of pressure (unlike
competitive brands). This insures that any leak in the tubing does not
blow noxious fumes into your room.
EXTERNAL VENTING IS BETTER
External venting is safer and surer than venting to the inside of your
kiln room with a filter.
The blower vents up to 130 CFM (cubic feet per minute). This will
handle up to a 20 cubic foot kiln (and usually larger). More than one
vent can be attached to a kiln. Only 1.37 amps.
SIX FOOT POWER CORD WITH ON/OFF
The blower motor features a 6 foot long 120 volt 15 amp power cord. An
On/Off switch is located on the cord.
ADJUSTABLE VENT CONTROL
A vacuum bypass on the kiln bypass/collection box adjusts the amount
of venting from the system. Don't waste heat and energy by venting more
than you need. Adjust vent to kiln size.
15-FEET OF FLEXIBLE ALUMINUM DUCT
15 feet of flexible expandable aluminum 3" diameter duct is included
along with necessary hose clamps. Longer lengths or lengths of 3" stove
pipe can be used as well. Length can be as great as 60 feet horizontal
or vertical with up to three 90 degree bends.
Skutt EnviroVent 2
VENT 2 KILNS W/ 1 MOTOR
Now you can vent 2 Kilns with one vent. The new 140 CFM Motor allows you
to vent 2 kilns up to 12 Cubic Feet each, or one kiln between 12 and 24
Cubic Feet, with one Envirovent 2 Motor.
WALL MOUNTED MEANS NO HEAT AND NO VIBRATION
The new design is wall mounted. This moves the vent motor away from
under the kiln so the motor is no longer exposed to the heat and can no
longer transfer any vibration into the kiln.
PLENUM CUP RETAINS SEAL THROUGHOUT FIRINGSPRING LOADED PLENUM CUP
RETAINS SEAL THROUGHOUT FIRING
As your kiln heats up the brick expands. When it expands the hot face of
the kiln floor, the inside, expands more than the cold face or
underside. This causes the slab to cup, or become slightly concave on
the bottom. The result is that the center of the kiln floor moves upward
at higher temperatures. The spring loaded cup follows the floor ensuring
a tight seal throughout the firing process.
NEGATIVE PRESSURE MEANS NO LEAKING
Since the vent is wall mounted it pulls the air through the duct work
instead of pushing it. This means if you were to ever form a leak in
your duct work the fumes would not be pushed into the room.
ABILITY TO CONTROL WITH KILNMASTER OR GLASS MASTER CONTROLLER
Now with the purchase of the new Skutt EnviroLink you can control
exactly when the Envirovent 2 turns on and off during a firing on a
GlassMaster or KilnMaster kiln.
SAME QUALITY VENTING
The EnviroVent 2 is a Downdraft Ventilation System designed to extract
fumes from your electric kiln and vent
them outdoors before they have a chance to enter the room. Because it is
a DownDraft Ventilation System the
EnviroVent 2 also improves the firing atmosphere in the kiln while it is
protecting you from the odorous fumes
that can be emitted from certain clay bodies and glazes when they are
fired. Venting FAQ's
Here's How It Works
A designated number of holes are drilled in the lid and floor of the
kiln either in the factory or on location. A spring loaded plenum cup
(see diagram) is placed under the kiln and tensioned between the floor
of the kiln and the floor under the kiln. The holes in the floor of the
kiln are drilled in a tight pattern so the plenum cup can cover them
all. The other end of the cup is connected by 3" ducting to a fan which
is generally mounted on the wall. On the opposite end of the fan the air
is ducted through the wall to the outside air. The plenum cup has 3
additional holes from which it draws room temperature air to mix with
the heated air from the kiln. This serves 2 purposes. Since the kiln air
is mixed with cooler room air the air coming out of the end of the vent
is never hotter than an average hair dryer. Secondly, the holes in the
plenum cup are sized to reduce the vacuum on the kiln chamber so only a
small amount of air is moving through the kiln. This ensures the firing
time is not affected and the ware is not at risk.

Kiln Stand Vent Adapter
The stand adapter is a
bracket that is designed to fit in between the cross
supports of your Skutt Rolling Kiln Stand. The
EnviroVent2 collection cup is spring loaded so it
can move up and down with the bottom of the kiln as
the brick expands and contracts.

WHAT IS THE ENVIROLINK?
The EnviroLink is an electrical switching device that can be controlled
by an automatic kiln to determine when a vent turns on and off.
CAN BENEFIT FROM AN ENVIROLINK?
Teachers - Even though most vents do not draw a lot of energy, most
teachers do not feel comfortable letting the fan motor run all weekend
or even overnight. The EnviroLink will shut the vent off when the
program is complete or when the kiln reaches a speciﬁc temperature.
Since it works with ConeFire Mode, it is very easy to program.
Potters - Crystal Glazes and Cone 6 Glazes can be very sensitive to
cooling rates. Artists can now use the Ramp/Hold programming mode to
control whether the kiln vent is on for each segment of the ﬁring
Glass Artist - Artists who ﬁre glass want to cool quick and hold
steady. With the EnviroLink they can pro-gram the vent to come on when
crash cooling and then turn off during annealing when they are trying to
hold the temperature steady.
WHAT KILNS WILL IT WORK ON?
The EnviroLink will work on any Skutt KilnMaster or GlassMaster Kiln
which was manufactured after January of 2001. If you are not sure how
old your kiln is write down your serial number along with the model
number, voltage and phase and call Skutt.The EnviroLink will also work
with many competitive brands. Call your particular kiln manufacturer to
WHAT OTHER VENTS WILL IT CONTROL?
It will control the EnviroVent, The EnviroVent 2 and any other DownDraft
Vent that draws less than 12 Amps. Consult with your Vent manufacturer
to be sure.

is an easy-to-install system designed for the
removal of kiln firing emissions. With Vent-A-Kiln, unpleasant fumes,
odors, and heat are captured at the source and safely removed from the
Pre-engineered, Variable-Height Electric-Kiln
Electric kilns use large
quantities of high-current electricity to generate the necessary heat to
properly fire artwork. In some instances, internal temperatures can
exceed 2200º F. Further, the clay medium experiences a metamorphosis,
which can result in toxic and odorous fumes exiting the kiln. These
heated fumes can accumulate and create an uncomfortable and dangerous
environment to work in.
Vent-A-Kiln was the first to
create a solution to this problem. By using heat's natural tendency to
rise, fumes and heat are safely exhausted away from the work area. This
allows the craftsman to create new work while firing ready pieces.
Please measure the exterior dimension of your kiln and choose among the
following systems that best fit your size. Remember, if you have a
square, rectangular or oval kiln, you must measure the longest
dimension; that is, corner to opposite corner. Round or multi-faced
kilns need only have the diameter measured.

Orton Vent Master
How does the Orton Vent
A small amount of air is drawn into and
through the kiln, collecting fumes and odors while improving firing
conditions. Small holes in the kiln lid let air into the kiln. Air is
drawn through the kiln drawing fumes and odors out through the floor.
The removed gases are then exhausted through ducting to the outside.
Where does it Attach to the Kiln?
There are some vent holes which must be
drilled into the floor and lid. We know, it's a new kiln and you don't
want to drill holes in it. We don't blame you, but it has to be done.
Ordering your new kiln complete
with a vent system relieves you of the need to drill. We'll do it for
you!! The Vent Master fits underneath the kiln using a small intake
plenum. Simply position the plenum under the kiln, taking care to
position it within the vent hole area and tighten the turnbuckle for a
Why is it important to vent the Kiln?
Many fired products contain organic materials
that consume oxygen during the early portion of the firing. Carbon
monoxide and carbon dioxide are formed. New air is needed to replace the
oxygen that is used.
Many fired products require an oxygen atmosphere to develop properly.
Oxygen allows for brighter and more vibrant color, especially red,
gold's, luster's and decals. Oxygen also allows for the complete burnout
of organics which reduces glaze fit problems like crazing. It also
eliminates porcelain mildew due to carbon.
Will it fit on my kiln?
Generally, yes. Most kilns do offer an open
area between the bottom of the kiln and floor surface. It's this area
that is used for the Vent Master kiln vent. Please feel
free to contact us regarding vent usage on particular models.
