Too much is indeed something to worry about. An oven relies on the
radiation to the surroundings to get off excessive heat.
Looking at the photos, it is not THAT much. Not very thick at all. See
the naked 10811 next to it.

But the manual *do* recommend to put them in a turbolent free
environment, essentially on in the normal air-flow of fans.
You can do a lot just by blocking direct flow of air.
