I just installed a Jotul F500 Woodstove replacing an older Jotul Alpha. The stove sits on 12”X12”, 5/16” thick Porcelain Tile. Under the tile is ¼” Hardibacker Cement Board which is over a subfloor of ¾” plywood and ½” plywood attached to 2X10 joists 16” OC.
When I “crank” up the F500 the porcelain tile gets very hot which it never did with the Jotul Alpha. The tile under the stove is hot enough that I am concerned about combustion of the plywood under the flooring and/or damaging the porcelain tiles. Of course, my main concern is the possibility of starting a fire beneath my floor. I attched the heat shield that comes with the stove and it cut the heat transfer to the floor considerably but there are "hot spots" on the tile near the rear of the stove.
Question: Do I need to or should I place the new F500 on a hearth pad to insure our safety or is the current configuration adequate? Thank you.
