So I get a call from a Gentleman in a 9 year old condo who is concerned his fireplace logs are deteriorating I agree to squeeze him in over the lunch hour. The fireplace is a basement direct vent with venting through a mainfloor chase and throught the roof. His fireplace has realistic logs with ember chucks that look like they fell off but thats the look of a good fireplace. I explain how the logs are made and don't burn. Anyway I see a couple dead bees in the firebox and decide to look up at the termination for signs of a nest. To my surprise all I see is a 4" B-vent termination on the roof. I knew this was wrong so I put a call in to the Manufacturer (on speaker phone) so the customer could listen in. It was clear that this was very dangerous so I had to shut it down.
After leaving I take a walk around the whole complex and see almost half or about 15 units with the same B-venting. Some had 7" DV terms and some had no vents. After some thought I realized that if the idiot that installed the B-vent could be soo stupid, who's to say he installed the DV term venting properly. I figure all units have to have drywall torn down from roof to basement to see if venting is continuous.
Anyone see this before? who was held liable? Builder? Technician? Condo Corp?
There are 40-50 Condos and the repairs are going to be $2000-$5000 per unit.
TSSA has been called in.
