How to Fix / Troubleshooting
Safety first: Turn off power and gas before inspecting venting in adverse weather.
Steps to mitigate weather‑related shutdowns:
- Inspect vent termination: Ensure the vent cap is properly installed and rated for the installation. Replace damaged caps.
- Check for water entry: Look for signs of water inside the flue collector or on the burners. Correct flashing or vent joints to prevent leaks.
- Wind effects: If the vent terminates in a high‑wind area, consider a wind‑resistant cap or relocating the termination per Raypak guidelines.
- Seal cabinet: Replace missing gaskets or seals on access panels to reduce water intrusion.
Note: Persistent weather‑related issues may require a venting redesign by a professional.
