HERMOSTAT

The griddle temperature control is carefully calibrated at the factory—that is, it is so adjusted that dial settings match ac-

tual temperatures. Field recalibration is seldom necessary, and should not be resorted to unless considerable experience

with cooking results definitely proves that the control is not maintaining the temperatures to which the dial is set.

Recalibration should not be undertaken, however, until the griddle bypass flame has been adjusted (see previous

subsection).
To check temperatures when recalibrating, use a test instrument with a DISC type thermocouple for surface temperature

checking. Drop a couple of drops of oil on griddle surface plate and place thermocouple disc flat into the oil.
Proceed as follows (see Figure 12):
1. Turn the Bypass Screw clockwise all the way in the off position. (When the scew is all the way in you may still see a

very small bypass flame.)
2. Turn the thermostat knob to the off position if not already.
3. Place a thermocouple (temperature probe) in the center of the top rack.
4. With the oven empty other than the rack and thermcouple, light the oven pilot and turn the thermostat to the

350-degree setting.
5. Allow the unit to run until the temperature of the oven stabilizes. (Make sure the bypass flame is off or very low at this

time.)
6. If the temperature of the thermocouple is

NOT within 15 degrees of the 350-degree set point, remove knob and

calibrate the thermostat accordingly with the

Srew in the center of the thermostat in very smallincrements.

7. Clockwise turn the temperature down and counterblockwise turns the temperature up.
8. Allow the oven temperature to stabilize again after any calibration adjustments.
9. Repeat steps 6 and 7 as neccessary until the calibration is within 15 degrees of the 350-degree set point and reinstall

knob.
10. Turn the thermostat knob down until the set point is between the first two marks after the off position.
11. Turn the Bypass Screw couter clockwise until the bypass flame is abouot 3/4 inch high. (The flames on both sides of

the burner should be starting to touch above the burner.)
12. Calibration is complete.
13. Note: The high bypass on Southbend cafe ranges will not allow the range temperature to run away.
