I have a computerized kiln equipped with a downdraft vent. Yesterday I discovered that a peephole plug is missing. Can I run the kiln safely with a missing peephole plug?

A motorized downdraft vent requires peephole plugs. You can still fire the kiln with a missing plug, but the vented kiln will not fire as evenly as it would with the plug. The vent will also allow some of the fumes to escape from the kiln if a plug is missing. So, we recommend that you wait until you get another peephole plug before firing the kiln with the vent.

As long as the kiln is installed correctly and you follow the safety guidelines listed in our instruction manuals, there is no safety hazard in leaving out one of the plugs. Also, there will be little heat loss through the open peephole as long as fans are kept away from the side of the kiln that has the open peephole. Please monitor the kiln during operation.
