- The serial number is on a data nameplate affixed to the control panel and represents the date the kiln was made.
- Usually, the last two digits (before any suffixes) are the year in which it was made.
- For instance, a kiln with Serial Number 0992A would have been made in 1992. The "A" in this number is just a sequential number for the day.
- Recent serial numbers have the distributor coded in a suffix.
