What is this white board(s) and tubes that are in the top of my wood stove? How do I replace it?

PLEASE NOTE:  The non-catalytic wood stove models utilize a new technology, which includes a ceramic fiber board that is located in the firebox, and rests on top of 3 stainless steel tubes. (Stoves with a '30' in the model number have 4 stainless steel tubes, and 2 pieces of fiber board, and stoves with a '32' in the model number have 5 stainless steel tubes, and 4 pieces of fiber board).

DO NOT remove this fiber board! It is a necessary component of the firebox. 

Also, please note: The ceramic fiber board may become loose during initial shipping.  Be sure it is lying flat, on top of the stainless steel tubes, and pushed all the way to the back of the unit, with no gaps between it and the back wall. Consult your Owner's Manual, and call Technical Support at (800) 245-6489 if questions.
