Possible Causes

Blocked condensate trap, Incorrect flue slope, Damaged condensate drain hose, Excessive condensation due to low return temperatures

How to Fix / Troubleshooting

Safety: Condensate is mildly acidic. Wear gloves and eye protection when handling.

  • 1. Inspect condensate drain: Locate the condensate trap and drain hose. Ensure the hose is not kinked or blocked and that it slopes continuously to the drain.
  • 2. Clean condensate trap (technician): Remove the trap, empty any debris or sludge, rinse with clean water, and reinstall, ensuring seals are intact.
  • 3. Check flue slope: The flue should be installed with the correct fall back to the appliance or to the terminal as specified by Beretta. A professional should correct any improper slope.
