wiring honeywell fan control when flue damper exists

[skr0oface]

so this is how i normally wire them.
black wire.. transformer gets powered after limit
black and yellow. to L1
white.. neutrals
brown N/C.. removed
red.. to hot side of blower.

now when there is a flue damper involved.. i would be lost. if someone could offer me help it would be nice.

What are you working on?

Automatic flue dampers are pretty scary. Even with a spill switch and an end switch, I still wouldn't sleep aa wink.

Scary yea. If it is a furnce with a flue damper, probally needs to be inspected. Might be rather old.
