How to Fix / Troubleshooting

Safety: Flue systems are critical safety components. Only qualified personnel should alter or dismantle them.

User checks:

  • Visually inspect the external flue terminal for obstructions and ensure no structures have been added nearby that could affect airflow.
  • 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.
  • Verify fan speed modulation and pressure readings at the air pressure switch.
  • Adjust or replace flue components to meet Ravenheat installation guidelines.
