I recently purchased a Mt Vernon AE Insert. Once installed I will be about 2"-3" short of the clearance requirement to have 6" of space to a non-combustible surface from the glass to the edge of the hearth. So I assume I am looking at a very small portable hearth pad of some sort to place on the hardwood floor in front of the raised brick hearth . Any recommendations on something very small to save me from spending a bundle of $$$$
