Adjustment of Thermostatic-Griddle Thermostat
Each 16”-wide section of a thermostatic griddle has a control knob that operates a snap-action thermostatic valve. Each
valve is adjusted at the factory. If the griddle surface temperature is different from the thermostat dial setting, adjust the
thermostatic valve using the following procedure:
1. Turn all the control knobs to the 300°F.
2. Wait 30 minutes for the griddle temperature to stabilize (or 1 hour if the griddle was cold).
3. Place a reliable thermometer or test-instrument thermocouple (able to register 300°F) halfway back from the front
to the back of the griddle and directly in line with the 16”-wide section’s control knob (see drawing below). Check the
temperature of each section every five minutes until the temperature does not change by more than 30°F between
two consecutive measurements.
4. If the average temperature of any section is not within 30°F of the knob setting (300°F), adjust the corresponding
thermostatic valve. To do so, remove the control knob (being careful to not turn the stem, which would change the
temperature setting). While holding the stem in place, turn the calibration screw (see drawing below). If the actual
measured temperature is lower than the dial setting, turn the screw counterclockwise. If the measured temperature is
higher than the dial setting, turn the screw clockwise. Replace the control knob.
5. Wait for the griddle temperature to stabilize, then again check the temperature (as described above).
Figure 20
Measure temperature of each 16"-wide section
half-way back and in line with control knob.
Each knob is attached to a thermostatic
valve located behind the valve panel.
Calibrate the thermostat by holding the
shaft in place while turning the screw
counterclockwise to increase the temperature,
or clockwise to decrease the temperature.
With a control knob removed,
its valve shaft will extend out
of the valve panel.
