I am still trying to decide on an insert but the 13NCI is high on the list but I have some specific questions. 1st off, is it possible to get a bigger surround. I am not sure that the one included will be large enough. My current insert has a surround of 34"x46" and I believe (haven't taken it off to verify) that it is really not extending very much over the brick. The nci surround is listed at 30"x42" and I am not sure that would work. Also, what is the burn time one of these? Is it capable of having all night and all day (8-10 hour) burns? Lowes said they could special order it for 1150. Should I be able to do better on the price?
