scotty said:I just went over this same thing with the local inspectors. They do not accept Hardibacker board or any other thermal barrier as automatically decreasing a stove's required "distance to combustibles". The only way a decrease is accepted is if the stove manufacturer's installation manual specifically describes the method of constructing the thermal barrier and also states the resulting decrease in distance. Just meeting National Fire Codes is nice, but not sufficient.
