I have only boiled sap on a block arch before but recently inherited a old sugar orchard and decided to make the leap to evaporating with a continuous flow flat pans. The pans that are currently in the sugarshack are quite a bit larger than I am comfortable using or capable of filling with sap for at least a few years. However, rather than try to remove a nice 5'x12' arch from the sugarshack, I am thinking of building a smaller arch to fit the new pans within the old rig.
Is there anything I should be wary of or consider for this?
The main things that I can think of are: making sure the new frame is level, making sure the fixings for the draw off clear the lip of the old arch walls with valve close to the pan, and looking out for places where heat might escape.
Thanks in advance for any advice given. I imagine that once I get to rebricking the arch I will be back for more help...
