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 will need to 
be replaced. 
5.  Once calibration is achieved, tighten the 
temperature dial screws and knob set 
screws.
