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 9 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 9 below), replace the knobs and control panel, then repeat
Step 3.
Figure 9
Calibrate the valveusing the Thermostat Calibration
Screw locatedat the base of thestem. Turn the
screw counterclockwise toincrease the temperature,
or clockwise todecrease the temperature.
Measure each temperature
halfway back from front to
back anddirectly over the
corresponding burner (in line
with the controlknob).
