Setup
1. Unpacking and Inspection
Carefully remove all components from the packaging. Inspect the heater and accessories for any signs of damage. If any damage is found, do not proceed with setup and contact customer support.
2. Placement
Place the heater on a flat, stable, and non-combustible surface. Ensure there is sufficient clearance around the heater for proper airflow and to prevent fire hazards. Maintain a minimum distance of 1 meter (3 feet) from walls, furniture, and other flammable materials.
3. Fueling the Heater
- Open the fuel tank cap.
- Fill the tank with clean diesel fuel. Do not overfill. Refer to the fuel level indicator.
- Securely close the fuel tank cap.
- Warning: Never use gasoline or other volatile fuels. Only use diesel.
4. Exhaust Pipe Connection
Connect the exhaust pipe securely to the designated exhaust port on the heater. Ensure the pipe is directed outdoors or to a well-ventilated area, away from any windows, doors, or air intakes. The exhaust must not be obstructed.
5. Power Connection
Connect the power adapter to the heater's power input port. Then, plug the adapter into a suitable 12V DC power source (e.g., vehicle battery) or a 220-240V AC outlet using the provided AC power cord. Ensure the power source matches the heater's voltage requirements.
