Hi, I will be installing a Harman 52i into existing fireplace (see picture), need help on how to raise fireplace inside floor:
There is a 7/8 inch difference between fireplace inside floor and the front (marble) hearth; how to raise the fireplace floor by just 7/8 inch and also to be able to mount the 52i frame on the new floor? I was thinking using two pieces of cement backer boards to reach 7/8 inch, would that be Ok? From the manual, there is no R value needed on the floor, i guess just need something the metal frame can be mounted on and stable.
Thanks so much. Have been reading and learning a lot from here.
