inspectorwill Posted April 23, 2010 Report Share Posted April 23, 2010 There are two heaters installed in the home. One on the 1st floor and one in the 2nd floor attic. The 1st floor vent extends up through the attic where the 2nd floor vent connects and then extends through the roof. The 1st floor unit has been replaced with a high efficiency unit and now vents through PVC elsewhere. The original vent was cut off just below where the attic unit vent is joined. Looking for any opinions as to the potential for venting problems. Many thanks. Photos attached for detail.

Bill Kibbel Posted April 24, 2010 Report Share Posted April 24, 2010 Is the remaining B-vent oversized now for the single system? Quote Link to comment Share on other sites More sharing options...
hausdok Posted April 24, 2010 Report Share Posted April 24, 2010 That's a good point, Bill. Did you record the model and Btu/Hr of the unit? You might be able to pull up the install manual online and see what size flue is required. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
