I’m having a good season in MA, Probably finishing up this week, with 125 taps, Hopefully 25+ gallons. Here’s an evaporator question. My Lapierre Jr 2x5 has run great, no complaints (with the exception of a
minor rust issue posted previously here, I’m getting good support from Lapierre). But I get a good hard boil Only in the middle section of the flue pan, and I’m wondering if relates to the arch and bricking design, because I’ve read others here saying different things about the gap between the top of the arch rails and the bottom of the raised flues (around .5” seems to be recommended). My arch has that gap of about .5”, but only for about 1’ of length, right in the middle where I get the hardest boil. From the fire box back, the fire box is around 24” long til the ramp starts which goes about 1’, then it flattens for about 1’ where the gap is .5”, but then the last 12-18” drops down 4-5” before it reaches the stack. It’s that 4-5” drop I’m wondering about, do others have that, and is it the cause of a slower boil that last 18” in the flue pan? Should the whole Pan boil hard like the middle? Would you add sand in that last 12-18” before the stack to make the gap a consistent .5” the whole way? I plan to call lapierre about it also since it’s their design and they obviously know what they’re doing.
