I'm more pissed off the CO detector didn't go off. I have the smoke detector ripped out because it started going off. Vacuumed it all out and just hanging in place. But didn't go off tonight, with a pretty good party going on. The basement has three separate exhaust fans, and double duty cold air returns so I guess the exhaust was getting out still pisses me off!
i know your a peng but they did replace the vent with the new white pipe .did he replace the venting with certified ulc s636 If so sounds like your ok with everything .
