Venting a Propane water heater issue
I need to vent my propane water heater. It is located in my basement which had multiple points of air ventilation. Between the bulkhead doors and poor pointing in the stone foundation. I am in the process of “tightening up” and sealing the basement for heat loss.
The water heater was vented to a hole in the wall where the furnace flu was exiting the house. I have sealed that as well for the furnace work work more efficiently and have pretty much only one option for the water heater. I have a small window which is pretty much useless in the basement that I was going to seal up and have the duct work go through for the venting. My issue happens to be a window to our livingroom is directly above the window in the basement.(Approx. 2-3 ft above) If I run the duct throught the boarded up window in the basement, will any carbon monoxide seep into the house through the livingroom window?
The WH is about 4 feet away from the basement window. So the overall travel, or length of duct, would be maybe 5 feet straight from the WH through the window and elbow up. Is there any kind or duct work or fittings or anything special for this type of situation? It is almost impossible to vent through the two floors above the basement and come out the roof.
Thanks for any help, Dave.

Why did you remove it from the furnace flu?
The furnace is oil first off. 2nd the furnace flu and WH duct were never tied in together. The flu duct was 8 inches and was sitting inside a 9 or 10 inch hole of the block chimney. The WH duct just ended at the opening for the chimney which still had a gap around from an imporper sized duct.
I since have installed new duct from the furnace and adapted a 8 X 10 reducer and all fits together well into the chimney.
The guy at the plumbing and heating place said, " It shouldn't be done, but I've seen a propane appliance vented with an oil fired appliance".
I want to do it right so I figured I would have a seperate vent for the WH but the windows are my concern.
My first guess would be to tie both together and put a SS liner in the chimney. I would call a chimney sweep.
