In past we had around 400,this year we have 2200 with 3/16 tubing and at the top of the hill we put in 4 vacuum gauges just to see what we were pulling,ranged from 15-25 inches of natural vacuum. We boiled our first run in the new to evaporator. We drew off 12gal yesterday and our evaporator is full of partially cooked down sap. Takes us about 400 gallons to safely fire up. Our setup is a 3.5'x9' raised flue with a steam away on top with air injection to really get it going. The steam away raised the sap temp up to 188 degrees so it is good and hot for when it goes down to the evaporator. We also have constant hot water coming into a tank from the steamaway. I have a bunch of pictures on my phone but for some reason I cant get them to go to my comptor.We are looking for another run wed,thurs
