So I just had my new P-68 installed this week. As you can imagine, she throws some heat. My wife had some aesthetic concerns about the firebox on that unit, as it's nowhere near as ornate as the P-52i we have upstairs. I think the off white firebricks look pretty ugly. I wanted to ask folks if these bricks serve any purpose as it relates to the overall heating effectiveness of the unit? I noticed that the log set they sell for this unit requires you to remove these bricks as the logs sit behind burn pot and stack up on the back of the stove. Before I went this route, I wanted to check with folks on what they think about the bricks. There has to be a reason why Harman put them in there, right?
