Need a little assistance with venting requirements for gas appliances. Focusing on the venting only, not exposed paper facing, flex ducts in garage, etc. Thanks gents…and ladies in advance.
Is a garage considered a confined space for combustion air? I have a high efficiency furnace and natural draft water heater in a single car garage that does not meet the 50 sq ft/1000 btu.
This water heater has a goose neck vent facing downward. I have never seen this application before and seems improper but I was not able to find anything specific on it.
