Gentlemen,
Inspected a home today with a 93+% efficiency gas forced air furnace. The 3'' schedule 40 PVC horizontal vent connector was over 42 feet long and vented out the sidewall of the home. The unit was in the basement of a very large home (unfinished) and the entire length was visible. I have never seen a PVC connector this long...ever. I can't find any info on the maximum length of a connector. The manuf installation instructions were there and i read them. It did not cover the max horizontal connector length just total height. It seems very long. It did say vertical was best option but nothing more. Any ideas or rules of thumb for total length of the connector?
