Standard Configuration Versus Same Side Reverse System

The Drop Flue Pan Set diagrams below illustrate the difference between a Drop Flue Pan Set with and without Same Side Reverse. On the standard configuration, you can reverse the flow of sap in the front pan by turning it 180º. In contrast, the Same Side Reverse System allows you to change direction of flow without ever moving the pan or dealing with plugs. You would simply swing the handles of two specialized Ball Valves.

The purpose of reversing the flow in the front pan is to eliminate the build-up of sediments on the floor of the pan. The frequency in which you will need to reverse the flow is dependent upon the speed at which sediments are being deposited the floor of the front pan. Typical volume of sediment varies greatly from region to region.

  1. Will Ewen

    I bought the 2×4 drop flue set with same side reverse. I also added the sight glass for the float box (highly recomended). Customer service and craftsmanship are 2nd to none! Even on my home made arch I’m getting 30 gal/hour and some of the nicest syrup I’ve ever made! The more I use this set, the more I realize how much thought went into the design. Smoky Lake has a life long customer in me!

    We have a 2×8. Hitting 90 gallons/hour with dry slab wood. The blower makes awesome heat available for boiling. 10 – 20 gallons syrup each day. Simply enjoyable to use. 2019 season is about done, cannot wait for next year!!!

  3. Lyle & Patti Bauer

    I went into Smoky Lakes looking to upgrade. After talking to Jim and giving him the information he needed we came out with a 2 x 5 drop flue pan set we also added a sight glass on the float box, awesome feature to keep a eye on your sap level. We put it all on a corsair arch and upgraded it all to stainless steel. We have had great customer service willing to answer any questions we had and the quality of their product is top notch. I managed to boil 35 to 40 gallons per hour off of natural draft. Such an upgrade to go from boiling all weekend to getting it done in one day. Loving my Smoky Lakes boiler and I can’t wait for next season.
