Chris Bernhardt Posted January 10, 2007 Report Share Posted January 10, 2007 Can one connect B-vent directly to the draft hood of a gas fired hot water heater? My understanding is that your not suppose to. B-vent is designed and listed for connecting to other B-vent and that listed transition pieces have to be used to interface to different vent types.

Jerry Simon Posted January 10, 2007 Report Share Posted January 10, 2007 On a related note, and perhaps *might* explain why B-vent shouldn't be connected to a draft hood, an HVAC guy once told me screws are not allowed in B-vent. Don't know if either is true, though. Quote Link to comment Share on other sites More sharing options...
hausdok Posted January 10, 2007 Report Share Posted January 10, 2007 Hi, I think it depends both on the type of application and on the manufacturer. The B-vent instructions on the Simpson Dura-Vent site say that it's okay to connect B-vent material directly to an appliance, but when it refers to the flexible B-vent material it says that a draft hood adaptor is required.
