Thanks for making this so simple! Painted exterior looks really nice!

Nice install but one key point was missed: the duct hose must be insulated outside of the conditioned space. This prevents condensation from forming inside the duct hose in the winter and the outside during the summer.

Nice tip, thank you.

@@buildsbymaz You're welcome! For future reference the max run is 35 LF and each 90 deg turn deducts 5 LF from that run. You wouldn't believe how many of these I do each year where the bathroom fans duct into the attic spaces.
