Hi MapleLady:
I like your idea of losing the buffet pans and getting the flat pan. Great move.
I have a flat pan with the valve also, I batch boil each time.
When it comes time to draw-off it is tricky unless your prepared.
What I do is, I have a setup with pallets stacked same height as the bottom of my boiling pan and pull the whole pan off the arch onto the pallets. I then use the spout to draw-off.
I have seen also a steel framed steel table used instead of pallets. Just use something strong and stable.
This prevents burning any sap, stops the boil immediately, gets you away from the fire while your drawing off.
It works for me and maybe can work for you. It also allows me to stop boiling at any stage and continue tomorrow if I want.
Good luck whatever you do and don't get burned from boiling sap !!
