Reverse flow (backflow?) with HE260

I thought I successfully installed a Honeywell HE260 humidifier this weekend. Everything works well - wiring, water, bypass ducting. However, when the furnace is on and the water is flowing through the pad properly, the air flow actually moves from the supply ducting back through the bypass ducting INTO the humidifier (I took the cover off the humidifier to confirm), instead of the mist from the pad getting sucked up through the bypass ducting INTO the supply ducting.

How can I fix that?

Here is a picture of my setup, with the bypass ducting sloping up from the humidifier to the supply duct. That is the absolutely ONLY place to put the hole in the supply duct, due to interference with the gas line, and ceiling up above.

I actually found the answer to my question in another thread: http://www.doityourself.com/forum/hu...questions.html - thank you DIY for having the information I needed! I'm glad to see that my installation is correct, and look forward to years of good humidification!
