Q1: From the past, I've always read to direct acidic vent condensate to the outside on a horizontal vent run or capture/dispose it if going vertical for condensating tankless water heaters. I've been reading up on Navien and Noritz units and they both say to tilt horizontal lines back toward the unit so condensate drips back into the heat exchanger. Navien also says its okay to vent vertically straight up. I realize that the vent condensate combines with the heat exchanger condensate and drips out of the drain plug. Why has this changed? Are heat exchangers more robust now that they are using stainless steel instead of copper?
Q2: With PVC vents, it is recommended to put a Tee as a termination.
or an elbow. Is there scenarios where one should use either one?
In regards to the tees, it seems like rain and wind can come down the vent with this configuration. Can one use a cap like this one from Noritz PRC-1? Or is the tee used because it allows a better flow?
Thanks!
