Never ever walk away from an evaporator. Its amazing how much can go wrong in the blink of an eye! We always run with two of us, one at the evaporator and the other watching every thing else, and standing in for lifes necessary stops!

your not primitive any more. This is much more a production process, This evaporator will need pretty much constant attention, either getting wood, firing the evaporator, checking or rechecking the sap levels, watching the syrup temp near the draw off, checking the density of syrup. Repeat the process several hundred times per season. You will be busier. Best to have several people watching some of the first boils till you have made several gallons of syrup off the rig. Good news you have made a lot of syrup and you have been through the basics of making syrup. This is a different tool. You will like it!
I love the four wheeler and the sap tank!

Just with wood stoves... smaller pipe will give more draft. It's physics
6" is just fine. Reduce it at the Evap not at the ceiling.
I would worry about the steam getting out of the garage more. Are you running a vent of some sort?

Chimney Size Should Match the Appliance
Chimneys that are over-sized for the appliance they serve are common, partly because people used to think that bigger is better. Now it is clear that bigger is not better when it comes to chimney sizing. A given volume of flue gas flows faster and has less time to lose heat in a small chimney flue than in a large one. In planning wood heating systems, experienced installers will sometimes choose a chimney that has a smaller inside diameter than the appliance flue collar.
