ADJUSTMENTS
CALIBRATION
1. Each thermostat controls a 12” zone of the griddle. Using
a Surface Probe temperature measurement device, observe
the temperatures at the center points of the cooking zones.
These points are located by starting 6” from the side splash
(left or right) and every 12” across the width of the griddle,
with all points located 12” back from the front edge of the
griddle plate. NOTE: Use of infrared thermometers is not
recommended. These devices are highly sensitive to
surface color (clean or dirty), angle of reading and distance
from the unit.
2. Set thermostats to 350°F and allow to stabilize, allowing
the burner to cycle ON and OFF at least two times.
3. Watch for burner to cycle OFF, then measure the
temperature for that zone. The temperature should be
350°F ±15°F. If not, continue to Step 4.
4. a. Carefully loosen the knob set screw. DO NOT allow the
knob to turn. Carefully remove the knob from the thermostat
shaft, exposing the temperature dial.
b. Loosen screws on the temperature dial and adjust to that
the temperature indicated by the knob arrow matches the
griddle plate temperature reading. Knob will have to be
placed back on the shaft to verify adjustment.
IMPORTANT: NEVER ADJUST THE SCREW IN THE CENTER OF THE THERMOSTAT
SHAFT. This will ruin the factory calibration; the thermostat will no longer operate properly and
may need to be replaced.
5. Once calibration is achieved, tighten the temperature dial screws and knob set screws.
