1. Important Safety Instructions
Please read all instructions carefully before using your KAMINIO Leni Electric Fireplace Heater. Keep this manual for future reference.
- Electrical Safety: Always plug the heater directly into a wall outlet. Do not use extension cords or power strips. Ensure the voltage matches the rating label on the appliance.
- Overheating Protection: The unit is equipped with an automatic overheat protection system. If the heater overheats, it will shut off automatically. Unplug the unit, wait 10-15 minutes for it to cool down, then plug it back in. If it continues to shut off, contact customer support.
- Clearance: Maintain a minimum distance of 1 meter (3 feet) from combustible materials such as furniture, curtains, bedding, paper, clothes, and other objects.
- Ventilation: Do not block air intakes or exhaust openings. Ensure proper ventilation to prevent overheating.
- Water Exposure: Do not use the heater in bathrooms, laundry areas, or similar indoor locations where it may come into contact with water. Never immerse the heater in water.
- Children and Pets: The exterior surface of the heater remains cool to the touch (Cool-Touch surface), reducing the risk of burns. However, always supervise children and pets around the appliance.
- Open Window Detection: The heater features an open window detection function, which automatically turns off the heating if an open window is detected, saving energy.
- Maintenance: Unplug the heater before cleaning or performing any maintenance.

- Placement: Place the fireplace on a stable, level surface in your desired room. Ensure there is adequate clearance from walls and furniture as specified in the safety instructions. The stable construction prevents tipping.
