NOTE:
A finish trim piece is shipped with your fireplace to extend the base
1/2" to be flush with the finish flanges on the side of the fireplace. This
filler is shipped on top of the fireplace wrapped in foam. If desired this
piece can be placed on the base of the fireplace. It is secured with bend
tabs on either side. Lay the extension in front of the base then secure by
bending tabs on each side over to secure to the base. While this piece is
provided it is not required.
