I was looking at my homeade arch today (oil tank) where I boil on. And noticed alot of heat fatigue, I realize it is going to be replaced at somepoint. I currently boil with a 2x3 drop flue pan and a 2x5 flat section syrup pan. Question if I bought a brand new CDL of Lapierre arch for these pans to go on (2x8). Is there a different arch for the drop flue than raided flue?? I will be buying a new set of pans at somepoint that will be raised.
