How to Fix / Troubleshooting

Safety: Condensate is mildly acidic; wear gloves and eye protection. Isolate power before opening the boiler.

Steps:

Locate the condensate trap and drain line. Remove and clean the trap of sludge and debris; flush with clean water.
Check the condensate pipe for blockages or freezing (in cold weather). Thaw and insulate as necessary.
Inspect the trap for cracks and replace if damaged.
Verify that the flue is correctly sloped towards the boiler or condensate drain as specified by Protherm.
Check flue seals and joints for leaks and reseal or replace components as needed.
