you guys are the pros and hoping you can hep me with this issue....


had a home inspection done on a house we are looking to buy, turns out owners put a new direct vent furnace in 6 months ago so basically the water heater is only gas appliance venting through original chimney now. There was no liner added either. How do I know if this is ok or not? from what I understand there could be issues b/c the current flu is most likely too big to just vent water heater alone and can cause some negative pressure issues?


Lastly the water heater is 14 years old so I am trying to get owners to replace it with a direct vent model based on it's age as well as how it is currently venteed now.......


owners are saying that it is a functioning water heater with no issues...


any help is greatly appreciated.
