3. Safety Information
Please read and understand all safety warnings before installing or using this product. Failure to follow these instructions could result in property damage, personal injury, or death.
- Professional Installation: Installation of exhaust systems should ideally be performed by a qualified technician to ensure compliance with all relevant safety standards and regulations.
- Ventilation: Ensure adequate ventilation during and after installation.
- Material Compatibility: Only use this kit with compatible heating systems and extractor hoods as specified by the manufacturer.
- Inspection: Regularly inspect the entire exhaust system for signs of damage, blockages, or leaks.
- Flammable Materials: Keep flammable materials away from the exhaust outlet.
4. Setup (Installation)
The Truma SL3002 exhaust chimney kit is designed for integration into existing or new heating and ventilation systems in leisure vehicles. The following steps provide a general overview of the installation process.
- Site Selection: Choose an appropriate location on the vehicle's exterior for the chimney, ensuring it is clear of obstructions and allows for proper exhaust dispersion.
- Hole Preparation: Carefully cut a hole of the correct diameter (approximately 65mm) through the vehicle wall at the selected location. Ensure all edges are smooth and sealed to prevent water ingress.
- Chimney Mounting: Insert the external chimney component into the prepared hole. Secure it firmly to the vehicle's exterior using appropriate fasteners and sealants to ensure a watertight and airtight fit.
- Hose Connection: Connect one end of the 65mm insulated hose to the internal connection point of the chimney. Secure it with a suitable clamp.
- System Integration: Route the insulated hose to the heating appliance or extractor hood. Connect the other end of the hose to the appliance's exhaust outlet, again securing it with a clamp. Ensure the hose run is as straight as possible with minimal bends to maintain optimal airflow.
- Leak Test: After installation, perform a thorough leak test of the entire exhaust system to confirm all connections are secure and no exhaust gases can escape into the vehicle's interior.

5. Operating Instructions
The Truma SL3002 Exhaust Chimney Kit is a passive component of your vehicle's heating and ventilation system. Its primary function is to safely channel exhaust gases from your heater or extractor hood to the outside environment and to provide thermal insulation for the ducting.
Operation of the exhaust system is directly linked to the operation of the connected appliance (heater or extractor hood). Ensure that the connected appliance is operated according to its own manufacturer's instructions. The chimney and hose facilitate the proper function of these appliances by providing an unobstructed and insulated exhaust path.
6. Maintenance
Regular maintenance of your Truma SL3002 Exhaust Chimney Kit is crucial for its longevity and the safe operation of your vehicle's heating and ventilation systems.
- Visual Inspection: Periodically inspect the external chimney for any signs of damage, cracks, or blockages (e.g., leaves, debris, insect nests). Check the insulated hose for kinks, tears, or disconnections.
- Cleaning: Clean the external chimney as needed to remove dirt or grime. Use mild soap and water; avoid abrasive cleaners that could damage the polypropylene material. Ensure the exhaust opening remains clear.
- Seal Integrity: Check the seals around the chimney's mounting point on the vehicle exterior. Re-seal if any signs of degradation or water ingress are observed.
- Hose Condition: While polypropylene is durable, prolonged exposure to UV radiation can affect its lifespan. Inspect the hose for signs of material degradation, especially if exposed to sunlight.
7. Troubleshooting
If you encounter issues with your exhaust system, consider the following troubleshooting steps:
- Reduced Exhaust Flow:
- Check the external chimney for blockages.
- Inspect the insulated hose for kinks or internal obstructions.
- Ensure the connected appliance's exhaust fan is functioning correctly.
- Unusual Odors Inside Vehicle:
- Immediately ventilate the vehicle.
- Check all hose connections for tightness and ensure they are properly clamped.
- Inspect the entire exhaust path for leaks or damage.
- If odors persist, discontinue use of the appliance and seek professional assistance.
- Visible Damage to Chimney or Hose:
- If any component is visibly damaged, it should be replaced immediately to ensure safety and proper function.
For complex issues or if you are unsure about any repair, it is recommended to consult a qualified Truma service partner or a professional technician.
