INSTALLATION AND USAGE OF THE WSE UPGRADE BUTTERFLY
The WSE butterfly upgrade provides a valve to close the connection between the flue pan and the syrup pan. This
eliminates the need to drain the flue pan when reversing or cleaning the syrup pan. Closing the valve additionally helps
maintain the gradient as closed it minimizes the reverse flow of sap to the flue pan.
