Temperature Calibration
Tools Required: Thermometer test instrument (not of bi-metal or mercury type), standard flat blade
screwdriver.
WARNING: DO NOT USE BI-METAL OR MERCURY THERMOMETERS WHEN TESTING FOOD
EQUIPMENT OR PRODUCTS. CHEMICALS WITHIN THESE INSTRUMENTS MAY BE TOXIC IF
EXPOSED TO FOOD.
1. Check the griddle temperature against the thermostat dial setting. Place thermocouple in center
of each individual griddle section. Each griddle section must be tested.
2. Light the main burner by turning the thermostat to 500°F.
3. Allow griddle to heat until the burner flame is heard cutting OFF. Wait about 10 minutes until the
burner flame has cycled ON and OFF several times. Then compare the test instrument reading with
the dial setting. If the reading is within ±15°F of the dial setting, its calibration is correct. If reading
is not within ±15°F, then recalibrate by performing Steps 4 through 13.
4. Pull the dial straight off the dial shaft (see Fig. 5).
5. Using a screwdriver placed through the dial shaft, push the metal dial insert out of the dial (Fig. 7).

6. Replace the dial back onto the range. Turn the dial to 400°F.
7. After the griddle has stabilized (at least 15 minutes), check the griddle temperature.
