2. Safety Information
WARNING: Failure to follow these safety instructions could result in fire, explosion, electric shock, or other serious injury or property damage.
- Carbon Monoxide Hazard: This heater produces carbon monoxide, which is an odorless and colorless gas that can cause death. Always ensure adequate ventilation when operating the heater. Never operate the heater in an enclosed space without proper exhaust ventilation to the outside.
- Exhaust System: The exhaust pipe must always be routed outdoors and away from any air intakes to prevent exhaust gases from entering the heated space. Regularly inspect the exhaust system for leaks or damage.
- Fuel Handling: Use only diesel fuel. Do not use gasoline or other volatile fuels. Refuel in a well-ventilated area and away from open flames or ignition sources. Ensure the fuel cap is securely fastened.
- Installation: Install the heater according to the provided instructions. Ensure all connections (fuel, electrical, exhaust, air intake) are secure and leak-free. Do not modify the heater or its components.
- Overheat Protection: The heater is equipped with overheat protection. Do not block the air intake or outlet. Ensure sufficient clearance around the heater for proper airflow.
- Electrical Safety: Ensure the power supply matches the heater's requirements (12V). Do not operate with damaged cables or connections.
- Children and Pets: Keep children and pets away from the heater during operation. The heater surfaces can become hot.
- Flammable Materials: Keep flammable materials, liquids, and vapors away from the heater. Maintain a safe distance from walls, furniture, and other objects.
