Question
Why is my fireplace putting smoke into my home? The flue is open

Answer
Hello Teddi, it is called a damper that is "open"  is this some thing new? What could be happening is you are getting Negative Pressure in your home (house stack effect) that is hot air rising in your home (and getting out through the attic vents, doors, lights, another fireplace (is it closed?)) your house is a better chimney than your chimney. Also kitchen/bathroom exhaust fans, clothes dryers, Radon systems and the boiler/furnace all take house air out of the house (mechanical negative pressure) your house needs make up air, perhaps an open window in the basement? Or stop the air from getting out the attic and other area’s.
Trail and error until you get this fireplace to work for you, maybe close off the room from the rest of the house to use it (close doors)
Or it could be dirty? I would have a local Certified Chimney Sweep (www.csia.org, there you can look up by zip code to find one near you) take a first hand look at what you have.
