    Default Raised flu sap level ?

    Just switched from a continues pan to a raised flu. How deep should I set the floats to before firing to be safe? 1" over flue and 1-1/2" in syrup pan? Never ran one and would rather start out cautious at first. 2' x 36" flu 2' x 18" syrup pan.
    Thanks!

    Those numbers are probably safe although 2" in both would not hurt till you get a feel for how she boils. It's ok if you occasionally see the top of the flues in the back pan when you have a rolling boil.
    Leader 3x8 Patriot raised flue
    800 taps on vacuum
    100 buckets around the yard
    A lot of help to make it fun

    Start at about 1.5 to 2" in both. As you gain confidence start lowering both.
    I now run my raised flue at 1/4-1/2" over the flues and the syrup pan at 1" deep.
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
