Hi all - We are installing an Explorer II in our new construction home and just realized the clearance above the stove is 55" - wow! We wanted to do a rock hearth with mantle, but now it seems like that won't be possible. Is there any way to get around this? Any other materials, a different set-up or reconfiguration that would make it possible? We are VERY new to all of this, so I really appreciate your help (and patience with a newbie)!
