Possible Causes
Incorrect flue slope, Failed flue seals, Cracked flue pipe, Blocked condensate drain in boiler
How to Fix / Troubleshooting
Safety: Condensate is mildly acidic; wear gloves. Turn off boiler before working on flue.
- 1. Check flue slope: Ensure the horizontal flue sections slope back towards the boiler as specified by Brötje, so condensate returns to the trap.
- 2. Inspect joints: Examine all visible flue joints for signs of water staining. Reseat or replace seals as needed.
- 3. Condensate trap: Clean the boiler’s condensate trap and confirm free flow to the drain.
- 4. Replace damaged flue parts: Any cracked or deformed flue components must be replaced with genuine Brötje flue parts.
