How to Hook Up a Smoky Lake Preheater:

At the rear of the preheater, the lower left pipe is where your cold sap will enter the system. It is recommended to use a head tank that has a shut-off valve. This will allow you to close off raw sap from your system at the end of a boiling day. Just don’t forget to open the valve again the next time you start boiling!

The hot sap will exit the system and go to the float box from the upper right.

The vent can be extended up from the upper left.

The lower right can be used as a drain. Most commonly a valve is added here. When you are finished boiling for the day, you will want to use this drain to remove the sap from the preheater. Otherwise, sap could freeze inside the pipes and cause damage.

If you desire, you could cap the upper left and the lower right and you can then branch the drain and vent off elsewhere else in the system.

The bottom left pipe of the preheater is connected to a head tank. The head tank will feed raw sap into the preheater. This particular head tank has a sight glass attached to it so that the operator knows how much sap is in it at all times. The top left pipe from the preheater is a vent. It must extend higher than your head tank.

We recommend using "Shark Bite" for plumbing

“Shark Bite” fittings will allow you to disconnect the pipes after the season. Otherwise, if you were to solder the pipes, it would be very difficult to remove your hood at the end of the season.
