The parts identification guides on the following pages have been designed to give a quick reference to component parts used on pilot ignition agricultural building heaters. The guides identify components not only used on current production, but also on equipment that is of earlier design. To use the guides properly, you should know the model numbers of the heater and its design sequence. This information is identified on the dataplate. Some models may have the design sequence shown as the 4th digit of the model number. For other models, the dataplate will identify a configuration number. The design sequence is the first digit of the configuration number. In many cases you will find components are common between different designs of the model number. Parts lists and schematics are shown on the following pages for the respective heaters. The parts guides also identify part numbers for the most commonly requested components, wires, and hardware items used on the heaters. If a wire, nut, or screw, etc. is not identified, please contact the L. B. White Co. for parts ordering information.
