Well, my fireplace (QF-7100) is still work in progress: they installed about a month ago, but no finish yet.
But since I couldn't wait and started satisfying my pyromaniac needs, I chose what seems like a good solution to keep for later too: I took my older stereo cabinet that I was going to toss, removed shelved and doors -- voila -- a stacking space that allows good drying ventilation!

Of course, additional impromptu wood stackings work too...
(Sorry for the bad quality image... )
Cheers,
Zevi.
