The Orton Vent Master is designed to vent the kiln while providing a fresh source of air (oxygen).

Available as an option on most Evenheat models.

See below for further details.

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. Ordering your new Evenheat 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 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. Some of our units such as the GT and GTS 22 cannot be used with the vent system. Feel free to contact us regarding vent usage on particular models.
