How to Fix / Troubleshooting
Safety first: If carbon monoxide is suspected, shut down the generator immediately, evacuate the building, and ventilate. Do not re-enter until it is safe.
- Verify installation clearances: Confirm the generator is installed at the minimum distance from windows, doors, and vents as specified by Champion and local codes.
- Check exhaust direction: Ensure the exhaust outlet is not aimed directly at the home or under decks or overhangs.
- Inspect exhaust extensions: If extensions are installed, verify they are not blocked or leaking.
- Install CO detectors: Ensure working carbon monoxide detectors are installed inside the home per code.
Relocating or reconfiguring the exhaust should be done by qualified installers following Champion guidelines.
