jodil Posted January 29, 2009 Report Share Posted January 29, 2009 Arguing with the builder on a double wall steel flue that enters the master bedroom closet, closet shelf cut around the flue and touches it (particle board) clothes are up against the flue... Whats the rule. I know I should know this but sorry..brain is overloaded with ice dam info ...thats why I have you Thanks Quote Link to comment Share on other sites More sharing options...
hausdok Posted January 29, 2009 Report Share Posted January 29, 2009 Per Code Check Complete Type B Double-Wall Connectors Min clearance to combustibles per L & L (typical 1in) [2006 IRC 242710.5/2006 UMC 802.10.5] ONE TEAM - ONE FIGHT!!!

Bain Posted January 29, 2009 Report Share Posted January 29, 2009 What Mike said about the 1". But even if the particle board is cut, the buyers will forget about the pipe and pile stuff around it that may catch fire. The builder should install some sort of a chase around the flue pipe so that can't happen. Quote Link to comment Share on other sites More sharing options...
jodil Posted January 30, 2009 Author Report Share Posted January 30, 2009 Thank you... That was my arguement... The builder himself lives in the house and all his wives clothes were packed in next to a hot pipe.. I just dont think its safe.

Mike Lamb Posted January 30, 2009 Report Share Posted January 30, 2009 Call the AHJ and see if the vent needs an enclosure. It probably does. The clearance to combustible thing is pretty clear. Builder's homes are often the absolute worst in following simple building and mechanical standards. I'd keep these references in your library. http://www.americanmetalproducts.com/ve ... ctions.pdf http://www.duravent.com/docs/instruct/shbook.pdf Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted January 30, 2009 Report Share Posted January 30, 2009 The 1" clearance thing is of course a given........just curious: Have any of you seen issues due to the lack of proper clearances at a B vent, especially several feet away from the source. I write up the inadequate clearance issues frequently, and am yet to see any actual problems. Quote Link to comment Share on other sites More sharing options...

I will call it out because the manufacturer says it's wrong. I will call it out but it is stupid. An incandescent light bulb in a closet is a huge fire hazard. Not plywood touching a b vent. Somebody must know better, I reckon. Quote Link to comment Share on other sites More sharing options...

Richard Moore Posted January 30, 2009 Report Share Posted January 30, 2009 Nice use of duct tape! Jim, what's with the PVC piping around the top of the furnace? Is that a condensate line or a self-melting fire-supression system in case things get really hot? Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted January 30, 2009 Report Share Posted January 30, 2009 I took this approach: Tell the customer (in writing) what the spec is for the pipe, tell them to make corrections as necessary, and then walk away knowing that they won't bother with fixing it anyhow. Agreed Jim-- nice pic. I kind of expected someone to post a picture with melted plastic or paper near the source, but that is much more than I expected. The only problem I've seen was when someone stuck the installation instructions right next to the draft hood of a water heater. The instructions had caught fire and half of the booklet was burnt up--- could have been a bad deal. Here's a discussion regarding B vent clearances to drywall that has some good points/ info: http://www.iccsafe.org/cgi-bin/ultimate ... 2;t=002006 Quote Link to comment Share on other sites More sharing options...

John Dirks Jr Posted January 30, 2009 Report Share Posted January 30, 2009 Jodi, Sometimes you just have to disagree with others and let it be. Report what you see, your concerns, and recommendations. When you know you are right, be done with it and don't bother wasting time on who disagrees with you. Thanks for asking questions on here. I learn from your posts too. Quote Link to comment Share on other sites More sharing options...

As a professional, one should work to a reasonable standard that's upheld by the whole profession. Middle-school students (grades 5 - are expected to be "fully accountable" for their spelling. If you want to work below that level, expect folks to recognize your attention to detail and respond accordingly. WJ oki doki - but i was not writing a report or else i would have thunk more.

Jim Katen Posted January 30, 2009 Report Share Posted January 30, 2009 Originally posted by Mike Lamb Jim, isn't that single wall venting? The elbow & the horizontal section are certainly B-vent. I'm not sure about the vertical portion. It might be single wall or it might be one of those adjustable-length B-vent sections. Either way, the B-vent elbow got hot enough to scorch the vinyl insulation wrap. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
