How to Fix / Troubleshooting
Safety: Flue systems are critical safety components. Only qualified personnel should alter or dismantle them.

- Note if E13 occurs mainly during high winds and inform your technician.
Technician checks:
- Inspect the entire flue run for correct assembly, support, and gradient.
- Check for signs of condensation leakage or corrosion inside the flue.
