Answer 2

Both of these papers are bring up the concept of heat flux. That's what you need to be concerned about with wood stoves. Big stoves put out proportionally more heat at the same temperature because they have larger radiating surface areas. In a nutshell, heat flux is what clearances are all about, not stove temps. You could hold a bright-red glowing poker (>1400ºF) 6" away from a wooden wall for months and it wouldn't ignite the wood because the heat flux is too small due to its extremely small radiating surface area.
