Generally, the furnace itself does not require a "break in" period. However, in the case of a new addition, several things are possible:

1) The fresh paint fumes you describe are probably being sucked into the cold air return only to be heated and recirculated through your home. This could be particularly noticeable if your painter used any Alkyd-based paints on the walls or trim. Alkyds have much higher VOCs (Volatile Organic Compounds) than latex paints and they typically continue to outgas for several weeks as they cure. You should definitely try to keep plenty of fresh air circulating throughout the new addition and avoid inhaling paint fumes. Keep your windows open -- even at night -- for the next couple of weeks, weather permitting. Also, check to see if your cold air return is located next to the source of fresh paint.

2) It's also possible (though unlikely) that the furnace is not properly venting or firing. This could lead to carbon monoxide poisoning which can also cause the symptoms you describe. If you have any questions or concerns, call your local utility supplier to have them run a routine check. They can check for gas leaks, proper combustion in the furnace, as well as carbon monoxide. Usually this service is free, particularly if you mention your safety concerns.

3) Finally, it's also typical that the first use of a furnace installed during new construction can result in significant circulation of dust that has accumulated in the cold air return and hot air vents. The airborne contaminants can include sawdust, fine white sheetrock powder (from sanding), and fiberglass insulation. Be sure to check your filter regularly and keep it clean. This isn't only important for proper furnace operation, but it's better for your health too.
