The Model UEAS natural gas-fired unit heater is designed for up to 93 percent efficiency. The unit heater contains a Tcore3® heat exchanger, single-burner combustion system, single-stage gas valve, multitry direct spark ignition with 100 percent lockout, and pressure switch to verify vent flow. Features include venter motor, aluminum venter wheel with housing, resiliently isolated axial fan and motor assembly, a high-temperature limit control, interlock door switch, and a built-in disconnect switch. The low-voltage terminal strip on the outside of the cabinet makes connecting control wiring easy with no panels to remove. The addition of a “G” terminal to the low-voltage strip, along with the new design of the circuit board, allows for fan-only operation (without adding relays). A propane conversion kit is included with the unit.
