    PRODUCED BY THE IGNITION UNIT. AVOID FIRE, EXPLOSION, AND ASPHYXIATION HAZARDS NECO Heaters are designed for drying crop output in grain bins. They provide heated air via grain bin plenums (found underneath full-floor bins) or via in-floor ductwork. Consult the NECO factory before attempting to use heaters for EZEE-DRY applications.

Though not strictly necessary, NECO highly recommends using a burner control device with a modulat- ing valve heater. When a burner control device is not used, jump the two terminals on the terminal strip in the heater control box normally used for the control device.
