    The r value has to be 1.5 so i want a 1 inch ventilated air space. i wanted to use wonderboard on top of stell studs but i dont see how .5 in wonderboard will support my stove?

    also, why is this stove so heavy and with such big clearances. ie 20 inches on the sides to unprotected surface.

    The wonderboard will support the stove so long as it is supported by sufficient steel studdage.

    why do you want an airspace under the stove? Are you just looking to elevate the unit?

    My inspector made me put in additional supports (2-3" lolly columns) underneath the stove as well. Not sure what my Oslo weights compared to yours but I'm glad I did
