Wiring Diagrams

Find Your Nameplate Data

Before ordering parts get your serial number, model number, voltage, phase, and other information on your data nameplate. See here for how to find this.

Find Your Wiring Diagram

Search for your wiring diagram below. Enter the beginning base number of your model (i.e., e23T for an e23T-240-1Ph kiln). Then, match the whole model number, voltage, and phase. If you don't find it, send an email to service@hotkilns.com with your model number and serial number, and we will send it to you.
