The force of the explosion had to come from within the grate pipe because
the walls were blown out at the seam of the stainless steel layer. I don't
see how any explanation could be fathomed where the cooking propane was the
cause of this unless it miraculously found its way into the tubing of the
grate.

The company rep said he had never heard of this happening, but they sent him
a new part.

That's what the blow out of the seam that runs parallel to the bar on the
bottom side of the grate looks like. The bent ss was forced away from the
center of the bar. In case anyone missed the op, the bars that make up the
ss grate are at least 1/4" thick with another type of steel inside. The ss
layer wraps that, hence the seam.
