Setup
- Unpack: Carefully remove the heater and all packaging materials from the box. Retain packaging for future storage or transport.
- Attach Feet (if applicable): Some models may require attaching feet for stability. Locate the two extra feet pieces and slide them into the designated slots at the base of the radiator until they are securely in place. This elevates the heater, preventing direct contact with the floor or carpet.
- Placement: Place the heater on a stable, level surface, ensuring it is at least 3 feet (0.9 meters) away from walls, furniture, and any flammable objects. Ensure the power cord is not obstructed or placed under the heater.
- Power Connection: Plug the heater into a standard wall outlet. Ensure the outlet meets the electrical requirements of the heater (120 Volts, 5.9 Amps).

Operating Instructions

- Adjust Heat Level: Turn the rotary thermostat knob to select your desired heat level. Options typically include 'LOW' and 'HIGH'.
