Why Do We Vent Kilns?
To Improve your Fired Product

All products fired in electric kilns contain organic materials that make carbon monoxide and other fumes when they are burned. These include clays, glazes, decorating products, decals and the like. Fumes released may contain sulfur oxides, hydrogen fluoride and metal vapors, depending on the products fired. Carbon monoxide and other fumes can affect the color and properties of the fired product if they are not removed from the kiln earlier in the firing. Red, green, gold and similar products are particularly affected by carbon monoxide at temperatures where the color develops.

To Improve your Work Environment

Removing fumes released from the kiln from your work environment is important, since these are unhealthy to breathe on a regular basis. Carbon monoxide can cause headaches and nausea. Other fumes can potentially cause health problems.

Methods for Venting
Typical methods for venting include:

Propping lid and keeping peepholes open until red heat - then closing up kiln
Hood above kiln to capture 70 to 85% of fumes released
Venting (such as downdraft venting) to pull fumes of kiln and pull in fresh air

Downdraft Venting
Orton invented downdraft venting some 15 years ago and it is the standard used to vent electric kilns. With downdraft venting, gases are pulled out of the kiln near the bottom of the kiln and then mixed with room air and exhausted to the outside through a duct.

Orton's downdraft venting systems are better than hoods because they improve firing conditions in the kiln and removes essentially all fumes from the kiln room. They will improve temperature uniformity in the kiln, extend the life of heating elements, Kiln Sitter parts and Type K thermocouples and reduce the cool down of your kiln by 4 to 6 hours. Also, with the Orton system, the kiln stays closed up during the entire firing. The Orton venting system is sold under the trade names KilnVent and Envirovent. Other manufacturers sell systems that pull fumes from the kiln during firing, but Orton has not measured their effectiveness.

The newer vents (VentMaster) have the motor mounted away from the kiln.  This keeps the motor cooler, and also if you pull the air out, instead of pushing the air from the kiln, you won't have fumes in your area even if your hose is leaking.

Oval kilns between 12 and 20 cubic feet should use a single vent master and an expansion kit.  One collector cup is installed on each end to promote more even venting.  Oval kilns larger than 20 cubic feet should use two Vent Master systems.

Here is a link to the Vent Master Installation Manual.  Please review for installation questions.  If you decide to operate the system entirely negative pressure, you'll want to purchase hose extension kits (read the manual and see the extension kit below).
