Setup & Installation
This VIVOSUN garage heater is a 240V unit with a no-plug design, requiring direct wiring to a dedicated circuit. It is crucial to follow all local electrical codes and safety regulations. We strongly advise hiring a licensed electrician for installation.
Installation Steps:
- Turn off Power: Ensure power is turned off at the main circuit breaker panel before beginning any electrical work.
- Access Wiring: Remove all screws from the bottom panel of the heater to access the wiring compartment.
- Run Wiring: Run the appropriate gauge wiring (e.g., #10 AWG for 40A breaker) through a cut-out on the side of the heater. Connect the wires to the Power Block inside the heater. This heater requires connection to 240V double live wires and does not require a neutral wire.
- Secure Connections: Torque all terminal screws and power block lugs tightly with the required torque (40 in-lbs).
- Mounting: The heater can be mounted on a wall or ceiling. Use the provided mounting bracket and hardware. Ensure the mounting surface can support the heater's weight (approximately 20 lbs) and that there is sufficient clearance around the unit (minimum 13 inches from wall, 7 3/8 inches from ceiling, and 8 feet from floor).
- Adjust Angles: Once securely mounted, adjust the vertical angles and louvers to direct heat as needed.
- Restore Power: After installation is complete and all connections are secure, turn on power at the main circuit breaker panel.

Troubleshooting
If you encounter issues with your VIVOSUN garage heater, refer to the following common troubleshooting steps:
- Heater Not Turning On:
- Check the main circuit breaker to ensure power is supplied to the heater.
- Verify that the heater is properly wired for 240V. If the fan runs slowly, it may indicate incorrect voltage (e.g., 120V instead of 240V).
- Ensure the power button on the unit or remote is pressed.
- Heater Not Producing Heat:
- Check the selected mode; ensure it is set to 'Low' or 'High' heat, not 'Fan only'.
- Verify the thermostat setting. If the ambient temperature is above the set temperature, the heater will not activate.
- Check for any overheating alarm lights. If illuminated, the unit may have shut off due to high temperature. Allow it to cool down.
- Remote Control Not Working:
- Replace the batteries in the remote control.
- Ensure there are no obstructions between the remote and the heater's sensor.
- Unusual Noises or Odors:
- Turn off and unplug the heater immediately.
- Inspect for any foreign objects in the fan or heating elements.
- If burning smells persist, contact a licensed electrician or VIVOSUN support.
