How to Fix / Troubleshooting
Safety: This is potentially dangerous (carbon monoxide risk). Turn off the boiler immediately, ventilate the area, and do not use the boiler until the fault is rectified.
- Visual inspection: Check all visible flue joints and seals for gaps, cracks, or signs of soot leakage.
- Check terminal: Ensure the flue terminal is not blocked or damaged.
- Do not seal with tape: Do not attempt to repair flue joints with tape or non-approved materials. Flue components must be replaced with Klimosz-approved parts.
