Oh man, SCORE!! Your system is going to come to life with that chimney improvement. Yeah, just plug right into it. It doesn't need to be airtight, but you can plug holes with fiberglass rope, furnace cement, cob, aluminum foil, foil tape, etc. Depends on the connection, but I bet it will have a thimble that you can just plug right into, maybe behind a wall plate? This is great news man! That will make a huge difference for your heater.
