It's not passing, you can feel it, put your hand there. Now it gets a minute to start drafting. Because it's got to heat the chimney out first. Yeah. So this is called spillage, and that's not good. But we're also putting a lot of negative pressure on the house. So then we'll try closing or shutting off all the fans in the dryer and see what happens. But that's not a good sign. But you're not normally going to have the house set up quite like this. Right. So you wouldn't have all the bath fans on and the dryer, well the dryer could be running all the switch. Dryer could be, yeah. So the dryer will be the main one we'll want to check, because that's a legit thing. We're coming right up on a minute, oh yeah, and you can feel the heat. Actually you can tell it's been back drafting, look at that right there where it's melted. Oh yeah. You're actually not supposed to have this quite that close to it, but it's also a sign if it's getting too hot. Yeah, we're past a minute.
