It's time to fire up the coal stove, now i need to replace the vent pipe. It's been slowly rusting away, and over the summer the cap fell off. The top 6" of pipe is pretty rusty. Anyway - I climbed up there yesterday and realized I have no idea how that pipe is attached...? Is it cemented on to the roof flange? I've seen roof flanges and piping at home depot - seems like a simple job if you know how to connect them. I thought maybe it spun and locked on but it doesn't.
Thanks for the help!
