THERMOSTAT ADJUSTMENT
Each burner’s control knob operates a snap-action thermostatic valve that was adjusted at the factory. If the
griddle surface temperature is different from the thermostat dial setting, adjust the valve using the following
procedure:
1. Turn all the control knobs to the 300°F.
2. Wait 30 minutes (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 over a burner (in line with the burner’s control knob, see
Figure 14 below). Check the temperature over each burner every five minutes until the temperature over
each burner stabilizes and does not change by more than 30°F between two consecutive
measurements.
4. If the temperature over any burner is not within 30°F of the knob setting (300°F), adjust the
corresponding thermostatic valve. To do so, remove the knobs and control panel, adjust the calibration
screw on the thermostatic valve (see Figure 14 below), replace the knobs and control panel, then repeat
Step 3.
Figure 14
Calibrate the valve using the Thermostat Calibration
Screw located at the base of the stem. Turn the
screw clockwise to increase the temperature, or
counterclockwise to decrease the temperature.
Measure each temperature
halfway back from front to
back and directly over the
corresponding burner (in line
with the control knob).
