I located my air mix valve so that the engine air to the cabin was between the two support ribs (aft side of firewall) on the right side of center. Then I encapsulated in that area between the ribs with fiberglass board (as used in making air-conditioning ducts and plenums). I tapped into that box for two outlets to go to the rear seats/two outlets to go to the pilots feet/two outlets to go to the defroster diffuser. The I have no control over these taps. But it works. It's very quiet-he seems to be distributed fairly well. The windows are cold , but the windshield defrost nicely. I've had as much as a quarter inch ice on the windshield and it came off in about three minutes using full heat. Charlie K. PS My flapper valve is permanently closed.
