How To Clean An Auto Draw-Off Valve
Your Great Lakes Guardian will diligently monitor the temperature in your stack so that you can maintain your heat within a target zone. This will help you maintain a nice even boil for great fuel savings.
If you are having any issue changing the efficiency setting, make sure that the LCY mode is set to 0. From the home screen on the Stack Temperature module, press and hold SET for 4 seconds. The efficiency setting will appear. From there, give the SET button another quick tap to toggle to the LCY mode. Change the LCY mode to 0. Then, quick tap SET to return to the efficiency setting.
For more information about changing efficiency settings, see page 31 – 32 of the Great Lakes Guardian Instruction Manual.
You can ask ten different sugar makers what their preferred stack temperature is and you will likely get ten different answers. Everyone’s setup is a little different, and there are a lot of variables which influence this answer. Keeping all other variables the same, take note of the amount of wood required to achieve different stack temperatures as well as the evaporation rate at each of those stack temperatures. Divide the number of gallons evaporated in an hour by the amount of fuel used. Whichever yields the largest number is your most efficient stack temperature.
