Sorry to burst in here.... I am a state licensed HVAC business owner and I couldn't help but notice your installation. Your furnace venting concerns me. If you do not have an appropriate rise in the vent (1/4" per foot) you need a power venter wired into the furnace for that horizontal run. It should be closest to the outside wall where the flue exits. From what I can see, with no rise or power venter, you will overheat the furnace's heat exchanger and eventually crack it. This leads to carbon monoxide poisoning which eventually leads to death. Sorry, just looking out for you. Bob
The unit does have a power vent, it's an Armstrong CGHA series, it was inspected the other day and was found to be to code, and installed per the vendors guidelines. My inspector had the same initial concern before we cracked the side cover so he could view the exhaust blower.

This system fires the exhaust blower first, then the heat exchangers, then the actual blower. The uint is controlled by a complex integrated circuit board that actually ****s down in the event that venting is not correct. On top of that I have affixed a digital CO meter in the garage for added piece of mind.

I chose this unit so I did not have to adjust for rise, I wanted a cleaner, easier installation.

Here is a link to the furnace specs:
