Ben H Posted December 6, 2011 Report Share Posted December 6, 2011 I know it's hard to see, but is this sectioned liner in upside down? You can see the end ridges on the connection pipe, right? I'm talking about the "background" connection, not the one the camera focused on. Click to Enlarge 50.66?KB Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted December 6, 2011 Report Share Posted December 6, 2011 It's OK. The joints are imbricated to direct creosote back to the firebox. Quote Link to comment Share on other sites More sharing options...

Erby Posted December 7, 2011 Report Share Posted December 7, 2011 Imbricating a wood stove or fireplace flue in the wrong direction allows creosote to flow out onto the exterior of the pipe and down on top of the fire box. A bad thing! http://b4uclose.tripod.com/cockamamieph ... k?i=28&s=1 On the other hand, imbrication of furnaces and water heaters is in the opposite direction.

Jim Katen Posted December 8, 2011 Report Share Posted December 8, 2011 . . . On the other hand, imbrication of furnaces and water heaters is in the opposite direction. Not really. In a B-vent, the upper liner sleeves inside the lower, just like on a woodstove. If you're using single-wall vent pipe, you should be sleeving it the same way, but few do. The result is condensation that runs outside the joints. Quote Link to comment Share on other sites More sharing options...

Chad Fabry Posted December 17, 2011 Report Share Posted December 17, 2011 That is OK. I agree with Chad Fabry. I have no idea who that poster is, but I know for certain that it is not my wife. Quote Link to comment Share on other sites More sharing options...
