msteger Posted September 11, 2007 Report Share Posted September 11, 2007 Did a 2006 build today and noticed that the condensing gas fired furnace's PVC vent pipe penetrated the roof and stopped. No cover or elbow installed. From the exterior (before going inside), I figured this was a plumbing stack vent. Common sense would tell me that this should have a cover of some sort to prevent rain water entry. Suggestions?? The gas water heater's PVC vent did have a cover installed at the top.

Richard Moore Posted September 11, 2007 Report Share Posted September 11, 2007 Any rain that enters, just like the regular condensate, will drain back to the pump resevoir and subsequently get pumped out. Not a problem IMO as long as it's the exhaust and not an intake. Link to comment Share on other sites More sharing options...
Scottpat Posted September 11, 2007 Report Share Posted September 11, 2007 Just to be safe, check with the manufacturer of the system. Some do have specific requirements that differ from the norm. Link to comment Share on other sites More sharing options...
