Kiln Venting Nabertherm Kilns
Nabertherm Kilns include an adjustable air inlet in opening in the kiln bottom for good ventilation and short cooling times. You can use stove pipe to vent out of your building or for the round top-loading kilns, get a Vent-a-Kiln hood type vent system which has the advantage of not only removing the fumes but also some of the waste heat although there is not a hood for the oval.
During ceramic firing, certain clays and glazes can release gases and vapors that may be harmful if inhaled. For this reason, kiln exhaust should always be safely vented outdoors. We recommend connecting an exhaust pipe directly to the kiln to properly remove fumes. For models up to the N 300/H, a 3.15" (80 mm) diameter zinc-plated steel or stainless steel pipe is suitable. The exhaust pipe must be installed with a continuous upward slope to ensure proper airflow. Good room ventilation is also essential so fresh air can mix with the exhaust gases. For planning purposes, the exhaust piping system should be rated for a maximum temperature of approximately 392°F.
⚠️ Safety Note: The bypass connection and exhaust piping can become very hot during operation and may cause burns. Any wall ducting must be made from heat-resistant materials. We strongly recommend having a qualified local ventilation company size and install the exhaust system correctly. For Top series models, the exhaust pipe must be connected to the bypass outlet using an upward angled bend, allowing the lid to open freely.
Thanks to Nabertherm’s optimized insulation design and precisely matched bypass system, no additional ventilation system is required to achieve excellent temperature uniformity. The manual air inlet damper allows fresh air to enter the kiln so residual moisture can escape through the bypass system and out through the side exhaust connection. Once the kiln reaches 1112°F, the damper can be closed to ensure consistent firing results and outstanding temperature uniformity.
