Chimney & Fireplaces/fireplace smoke coming in home


i have smoking coming into my home from my temco tlc363n fire place cant figure out why or how its been a very calm 40degree day no wind i dont understand !!!!

What is 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 (, there you can look up by zip code to find one near you) take a first hand look at what you have.
