DonTx Posted April 17, 2004 Report Share Posted April 17, 2004 The chimney structure is for a Heat-N-Glo model SL950TV-C and the short flue is from a SL550TR-C. Do direct vent flues fall under the 2/10 rule? The short flue was about 5 feet away from the Chimney structure and about 6-8 away from the roof to the right.

Brian G Posted April 17, 2004 Report Share Posted April 17, 2004 Hey at least they put a cricket behind the chimney, hardly ever see 'em here. They usually just flash straight across and caulk like hell. Brian G. Quote Link to comment Share on other sites More sharing options...
Konrad Posted April 17, 2004 Report Share Posted April 17, 2004 I just read this the other day in my Code Check tablet. Its a variation on the 2/10 rule, basically, 2/8: "If closer than 8 feet toa wall, vent must extend 2 feet above roof." That framed chimney isn't exactly a wall. I might try explaining that wind oscillations on the downwind side of the framed chimney would possibly cause backdrafting of the flue, on occasion. But more importantly, you appear to have the manufacturer's identity. They are the best advocate you can probably have. What do they say?

washirw Posted October 14, 2004 Report Share Posted October 14, 2004 So Donald, What did you decide to write up on this? That is, if you can remember something this many months ago. Thanks. Quote Link to comment Share on other sites More sharing options...
Steve Knight Posted October 14, 2004 Report Share Posted October 14, 2004 I just inspected a Heat-N-Glo gas fire place and found their product installation manuals on the web at http://www.heatnglo.com/products/fireplaces/index.asp. The model I inspected was SL-550TRS-D. There was a table in the installation manual showning minimum height from roof to lowest discharge opening (bottom of termination cap). The required height above the roof depends on roof pitch. The roof I inspected was 6/12 and required height above roof was a minimum of 12". The termination cap is also suppose to be 2' minimum from a vertical wall or horizontal overhang. Quote Link to comment Share on other sites More sharing options...
