I had a power vent gas water heater in my Michigan home for over 27 years. Well, it was three water heaters in the time I lived there, but the installation was original to the home, venting was with PVC (3"). There was a period of time when these were popular in Michigan but they are a bit more costly. Worthy of investigation as venting can be very costly or impossible in some cases. The PVC venting makes it VERY easy.
After our home was built there, the local rules changed about how far above grade the vent and in some cases, the intakes had to be so you saw all these "periscopes" added.
