Yours is better placement. I can hear when the fan comes on and I probably enclosed some air flow by boxing in the space under the mantle. I want to think that reflects listening to customer feedback and responding. When I left Bend Oregon with my Mammoth, I was warned that the plastic channel/track for the radius bath door was in the process of being redesigned and when it failed, I could have the new generation. They were still searching for a vendor and material to gently roll the radius without crushing it.
True to their word, I received the material and installed the rail and hardware. They shipped everything and more so I had enough 2.5" wood material to skin my metal track both outside (dining) and inside the bath area.
