Vent slope


Recommended Posts

Power vented water heaters are not high efficiency systems that generate much condensate. They maintain cool exhaust temps by drawing in a large amount of air to dilute the exhaust. The vent doesn't slope back to the unit because they don't have a condensate collection and discharge system (unless there's an unusual situation).

Horizontal vent pipes should be installed to slope away from the blower, to drain any possible condensate to the exterior.
