Bain Posted July 8, 2011 Report Share Posted July 8, 2011 I haven't. The chimney wasn't removed as far as I could tell. This is how the house was built fifty years ago I suppose the gas logs would draft okay once the flue--yes, I realize it's a single wall--heated up, but before that happened? Without a conical transition, I would think the effluent would hit the flat portion of the galvanized metal and backdraft into the house. Click to Enlarge 57.05 KB.

AHI in AR Posted July 8, 2011 Report Share Posted July 8, 2011 It's a good thing that fireplace hasn't been used much. It's just plain goofy. It appears to be constructed with relatively soft and porous "antique" brick. Not a good mix with a gas burning appliance. I suspect it was someone's attempt to create a budget chimney. I have less of a concern about the lack of a conical transition than I do the fact that it is single wall pipe. As big as the interior of the chimney is, I see a lot of potential for condensation. Looks to me like a good candidate to be relined. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted July 8, 2011 Report Share Posted July 8, 2011 I'd feel much better condemning that thing than blessing it. [] Quote Link to comment Share on other sites More sharing options...

Hearthman Posted July 8, 2011 Report Share Posted July 8, 2011 This is a Kervorkian fireplace. Someone went to a lot of trouble to kill themselves. this fireplace does not have a chimney What is there is severely downsized IT offsets more than 30* from vertical It is a death trap Whomever did this should be arrested There is listed factory chimney made to transition from masonry and vent vertically legally. This ain't it. Quote Link to comment Share on other sites More sharing options...

This ain't it. Ha, ha, ha. That's pretty much what I said. IS a 4" b-vent suitable for gas logs? I assume there's some sort of BTU-to-diameter ratio, but I've never looked into it. I told my buyers they needed to have a sweep determine whether a replacement vent would be acceptable. Quote Link to comment Share on other sites More sharing options...
