Dunno, you can try calling APE  ... but read on.

I'd suggest putting some sort of heat shield in place, even if its just a
piece of sheet aluminum.

A couple of suggestions for you:

1. Try making up two heat shield forms from aluminum and putting them on with
a small (a fraction of an inch) air gap between them. You'll find
cookie/baking sheets like this at your upscale kitchen stores (hmmmm, a new
supplier).

2. Make two forms, as per above, but locate some ceramic cloth insulation (I
think that's the term) used in lining boilers and place it between the two
sheets. I had some installed in my old oil burning house boiler/furnace as
insulation inside the fire pot and it worked great. It's a non-toxic
replacement for
asbestos.

I suggest the aluminum for three reasons - 1. it doesn't rust/corrode as
quickly as steel; 2. it has better heat transfer characteristics (to this
untrained person, YMMV); and 3. it's lighter. Number three is the most
important, of
course ... :-)
