Furnace venting issue
Here is my problem...I have a 6 year old home that has a furnace that vents through the side wall of my garage. During the winter the steam freezes and builds up on the siding and creates a large ice patch that has discolored the siding. However, this is the least of my problems. I noticed that there was water stains on the inside base of my garage where the garage meets the foundation. I cut open around my vent on the insdie and there is a lot of moisture inside my wall. You can tell that my OSB walls have swelled from moisture build up. Now I am assuming that I need to remover my siding because of the integrity of my wall. What I want to know is there a venting sytem that I can use that will prevent this from happening again? I have PVC pipe vented out the side of my house connected into a basic dryer vent that has been caulked. I am assuming that this was completed incorrectly because I will have to replace both the iside wall and under the siding.
What do you think?
