5. Setup and Installation
Proper setup is crucial for safe and effective operation. Refer to the included English instruction manual for detailed diagrams and specific steps.
5.1 Site Selection
- Choose a flat, stable, and non-combustible surface for the heater.
- Ensure sufficient clearance around the heater (at least 1 meter / 3 feet) from any flammable materials.
- Position the heater so that the exhaust pipe can be safely routed outside the enclosed space.
5.2 Exhaust System Installation
- Connect the exhaust pipe to the heater's exhaust outlet. Secure it with the provided clamps.
- Route the exhaust pipe directly to the outside, ensuring no kinks or blockages. The exhaust must exit completely clear of any air intakes or windows.
- Install the silencer (if included) on the exhaust pipe to reduce noise.
5.3 Air Intake and Outlet Installation
- Attach the air filter to the air intake pipe and connect it to the heater's air intake.
- Connect the outlet air pipe to the heater's hot air outlet. Direct the hot air flow as desired, ensuring it is not obstructed.
5.4 Fuel Filling
- Ensure the heater is turned off and cool before adding fuel.
- Open the fuel tank cap and carefully pour diesel fuel into the 5L tank. Do not overfill.
- Securely close the fuel tank cap.
5.5 Power Connection
- Connect the 12V power harness to a suitable 12V DC power source (e.g., vehicle battery).
- Ensure correct polarity (+ to + and - to -) to prevent damage.
