New to me 36" X 6' Drop flu pan and 36 x 48 syrup pan. No more dumping sap. Firebox q

OK, You guys have helped sober me up. My goal was just to not dump any more sap with the limited time I have to boil so I think what I am going to do is just scale my project back a little and build and arch for the 3X6 Drop Flue pan. I will still need to batch but I will get great rate of evaporation so a night of boiling should produce double the results or more of my old set up and still have enough sap to run the thing for a few hours at a time. I cant wait to have 300 gallons of sap just to fire this thing up, I need to be able to deal when the tank has just 100 gallons in it as well.
Building an arch for a drop flue pan that will sit directly over 24" of fire box may cause an issue because I do not want to damage the Flues when loading wood.Evap idea.jpg

Will the fire box be to low in this scenario?

Thank you all for your help.

Your 36 x 48 syrup pan is meant to be above the fire and the flue pan begins at the top of the ramp. So your basic drawing is a good start you just need to stretch the arch out more and slope the ramp beginning at about 2/3's the way up the fire box backside. You will need to remember that insulation and fire brick or vermiculite will be needed to fill in the space to within about 1/2 inch of the bottom of the flues. I may be incorrect on this measurement. Dave will probably be able to give us a better answer.

I am back! LOL! First lets just say that you guys / Gals are fantastic to share your knowledge. I will post some pics of the new arch. It is coming along nicely.
New question is will my 8" stack be ok with this new 3 X 6 arch or do I need to increase the size? Looking for a new roof flashing and want to get what I need and not just fit what I have.

Thank you!

8" should be fine.
