What does "get it going" mean? How come "going" was used here?
To "get something going" is a phrase that means to succeed in starting something. In this case, Ross is referring to starting the fire in the fireplace, but it can also refer to starting a machine, vehicle, a process, etc. Ex: Let's get the car going so we can get out of here. Ex: I'm going to get the tea going while you work on that.
