Condensation white powder on boiler and vents. What's the remedy?
Posted by Michael Drehl, on
Hi. I have a Laars JVS boiler venting into a chimney liner. It is properly sized. The boiler was installed two years ago. On the vents and the air intake on the boiler is showing some white powder and solidified white drippage on the vents. The vents are starting to corrode. I am thinking it is because of condensation from the boiler. It is not from the chimney as it all looks good on the cap of the chimney at the top. No leakage there.
