I saw one member , I think CWR stated his air is 320 degrees . WOW I thougt I was cooking at 225 degrees . At 225 My stove is getting pretty hot on the surface and the exhaust pipe is really hot. I have the US 6041 (MULTI-FUEL) . I think I would worry if was any hotter, the inside hopper surface facing the front of the stove gets pretty warm too I know all stoves are different quality and different max heat ratings, but what would be a good guess at My Max. output before the stove would shut itself down ??????? Thanks
