• Ventilation: Ensure adequate ventilation in the area where the heater is operating to prevent oxygen depletion.
• Fuel Handling: Use only diesel fuel. Do not use gasoline or other volatile fuels. Refuel in a well-ventilated area away from ignition sources.
• Overheating Protection: The heater is equipped with overheating protection (≥ 270 °C). Do not obstruct air inlets or outlets.
• Electrical Safety: Verify correct voltage (12V/24V DC or 110-240V AC) before connecting. Protect against short circuits, overvoltage, and reverse connections.
• Placement: Place the heater on a stable, non-combustible surface. Maintain a safe distance from flammable materials.

5. Setup

Proper setup is crucial for the safe and effective operation of your diesel heater.

5.1 Placement

• Place the heater on a flat, stable, and non-combustible surface.
• Ensure there is sufficient clearance around the heater for air circulation and to prevent fire hazards.
• Do not place the heater directly on carpet or other flammable materials.

5.2 Exhaust System Installation

IMPORTANT: The exhaust pipe must always be routed outside and away from any occupied space to prevent carbon monoxide poisoning.

1. Connect the exhaust pipe to the heater's exhaust port using the provided clamps.
2. Route the exhaust pipe securely to the exterior, ensuring it is not obstructed and is positioned where exhaust gases will disperse safely.
3. Install the silencer (if desired) onto the exhaust pipe to reduce noise.

5.3 Air Intake and Outlet Pipes

1. Connect the intake pipe to the heater's air intake port. This pipe draws in fresh air for combustion.
2. Connect the air outlet pipe to the heater's hot air outlet. This pipe directs the heated air into the desired space.
3. Ensure both pipes are securely fastened and free from kinks or obstructions.

5.4 Fueling

1. Open the fuel tank cap.
2. Fill the tank with clean diesel fuel. Do not overfill.
3. Securely close the fuel tank cap.

5.5 Power Connection

The heater supports dual power supply options: 12V/24V DC and 110-240V AC.
