Would it work to insulate the ductwork somehow? A layer of fiberglass or pipe wrap or some non-combustible material between the woodwork and the heat might give you better peace of mind. Although I think 192 is well below the ignition point for wood (400+ is in my mind somehow) and you're probably safe, it never hurts to be absolutely sure...

I may have the same issue - I just re-routed my one duct from Harman magnum to opposite side of room. There is a 2x12 boot that fits snugly in a hole I cut into the floor next to wall. Last night I fired up the stove and after the stove got going the one vent ( I had the front of stove blocked with fiberglass insulation), the temp of the hot air coming from the vent was probably about 170-200. Before I went to bed I took part of the insulation out of the front of the stove opening and the hot air coming from the vent went down significantly - however the upstairs living room was not as warm. Stove is in the basement.

I was thinkings of widening the hole where the boot fits in about 3\4" all around and then stuffing fiberglass insulation around the edges.

What do the coal-timers on here suggest. I saw the post that it takes 400 deg temps to ignite wood but don't want to press my luck either. I have a 1924 4 square with oak floor and "plywood" sub floor that I cut through to basement to link the boot and 6" duct to. I don't have a lot of wiggle room beneath the area of the floor to make any special duct box etc...
