Orton KILN VENT MASTER 120V M9 VENT MASTER

The patented Orton Vent Master not only vents fumes but also improves firing results.

It pulls fresh oxygen into the kiln for brighter colors, especially noticeable with red and orange glazes and decals. Fire red and green glazes in the same load without glaze contamination. The Vent Master draws air from the kiln, dilutes it with room air, and pushes it outdoors through a vent hose. The extra oxygen and increased air movement help burn carbon out of the clay, which helps eliminate a host of firing problems: bloating, dark patches in the clay, porcelain mildew, pinholes, pitting, blisters, and bubbles.

The Vent Master removes fumes containing volatile metals, fluorides and sulphur oxides. You can fire even lusters, decals, metallics, and pate-de-verre glass without strong odor.

The flow of fresh air helps even out the temperature throughout the kiln. The vent also extends the life of the Kiln Sitter tube assembly, since fumes by-pass the tube. You will enjoy the convenience of the Vent Master. Throughout the firing, keep the lid closed and peephole plugs inserted. You no longer need to remember to lower the hot lid from vented position.

The Vent Master increases firing time by about five minutes for firings up to cone 4; 12 minutes for firings from cone 4 to 10. It has little effect on maximum temperature. At 132 watts, electrical consumption of the Vent Master motor is only pennies per firing.

From the shut-off temperature down to 1000�F, the Vent Master has little effect on cooling time. From 1000�F to room temperature, it reduces cooling time by about two hours.

As with Paragon kilns, the Orton Vent Master can be made for any electrical system in the world. Approved for use in the 1992 Uniform Mechanical Code. UL/CSA approved for UL Listed kilns. ETL Listed, CE Certified. Two year limited warranty.

The Vent Master requires a separate 120 volt wall plug unless your kiln is equipped with the AOP vent.

Orton Vent Master Operation

How does the Orton Vent Master Work?

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.  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 snug fit.

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. . Feel free to contact us regarding vent usage on particular models.
