	This seems a little excessive, unless I'm not understanding
	something. All we do is put a blower running full tilt behind
	a blast gate.  When work comes out of fire, we close the gate
	and all blast goes away.  If we need some to maintain heat,
	we leave the gate cracked a bit.  Works very well and is as
	simple as it gets.
