One word of advise on your first outing, especially if the dealer didn't tell you on your walk-through......
Open all windows and door, turn on exhaust fans and turn your furnace on and let it run for a few minutes. This burns off any oils, residue, etc. off the burner and won't set the smoke alarm off.
Don't ask me how I know.......
