DynaChem has a 1967 Kewanee, 250 HP, gas-fired, fire-tube boiler
with an E-type burner.We need an electrical schematic for the gas fired system. Since the Kewanee is older than 1970,Are any manuals, drawings or schematics available for this unit. The boiler name plate is as follows:The serial number : NB-23335.The Order Number: 416840AManufacturing year: 1967
JA: Thanks. Can you give me any more details about your issue?
Customer: Jim Hartman, EngineerThe boiler will not go to automatic fire from low fire. When manually put into automatic fire, the boiler operates OK. There are some changes that need to be made . The boiler tuner recommended a new 135 ohm pot and a L91A controller. The wiring is in poor condition. That is why we need the wiring schematic.
