I have a peerless purefire, and got a "blocking error #E05." What's the best solution for this?
The "Blocking Error #E05" on a Peerless Purefire boiler usually indicates that there is a blockage in the vent or exhaust piping, which is causing the pressure switch to open and prevent the boiler from firing. The best solution for this issue is to check the vent and exhaust piping for any blockages, such as debris or snow, and clear them out. Additionally, it may be necessary to check the pressure switch and ensure that it is functioning properly. If the issue persists, it is recommended to contact a licensed HVAC technician for further assistance.
