"See-Though” versus “Double Face”

QUESTION: What is the difference between “See-Though” and “Double Face”?

ANSWER: Same thing, different words. The terms may be used interchangeably. Fireplaces which have two sides open, front and back, are termed “See-through” fireplaces. They require “Double Face” gas log sets. DF sets have two front logs (rather than a larger front and smaller rear logs used in Single Face sets) and a parallel grate (teeth upturned on the front and back), so that the appearance is the same from both sides of the fireplace.
