New old house, basement fireplace has a fan forced to duct, tie to cold air return or make a ceiling vent near cold air return?
So the fan is mounted on the outside of the house pulls fresh air around heater box and sends to a 8" duct. How should I finish this off? Drywall starts in 2 weeks and need to finish this off. Really pumps out the heat!
