For all the Englander 10-CPM owners out there, I need help figuring out what size hearth pad I need for this unit. I need dimensions for a corner pad that I'm planning to make myself. Can't justify paying $600 for a pad with slate stone. I'm planning on a basic portable one to go right on top of the carpet with tiling and a wood trim. Would a 48"x48" be too big for this stove? Any suggestions would be greatly appreciated! Thanks! Pictures would be awesome!
