HEAVY DUTY COUNTERLINE ADJUSTMENTS

ADJUSTMENT OF GRIDDLE THERMOSTATS

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 18 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 average 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 18 below), replace the knobs and control panel, then repeat Step 3.

Figure 18

Measure each temperature halfway back from front to back and directly over the corresponding burner (in line with the control knob).

Calibrate the valve using the Thermostat Calibration Screw located at the base of the stem. Turn the screw counterclockwise to increase the temperature, or clockwise to decrease the temperature.
