4 . Carefully remove the thermostat dial, not disturbing the
dial setting .
5 . Hold the thermostat shaft steady with a small flat blade
screw driver . Turn the calibration screw located inside the
shaft clockwise to decrease the temperature and counter
clockwise to increase the temperature . NOTE: each ¼ turn
of the screw will create a change of approximately 35° F
(20°C) .
6 . Replace the thermostat dial and repeat steps 1 though 3
to verify that the correct adjustment has been made .

Griddle
1 . Use a test instrument with a special disc type
thermocouple or a reliable surface type pyrometer . NOTE:
a drop of oil on the face of the disc will provide better
contact with the plate .
2 . Set all griddle thermostats to 350°F (177°C) . In order
to allow the griddle temperature to stabilize, the
thermostats must be allowed to cycle twice before taking
a test reading .
3 . Check the griddle temperature when the thermostat just
cycles “OFF” by placing the thermocouple firmly on the
griddle directly about the sensing bulb of the thermostat .
The reading should be between 335° F (168°C) and 365°
F and (185°C) . If the reading is outside of these limits,
calibrate as follows:
4 . Carefully remove the dial, not disturbing the shaft
position .
5 . Hold the shaft steady and with a small flat screw
driver turn the calibration screw located inside the
shaft clockwise to decrease temperature and counter
clockwise to increase temperature . NOTE: Each ¼ turn
of the screw will create a change of approximately 35° F
(20°C) .
6 . Replace the thermostat dial and repeat steps 1 through 3
verify that a correct adjustment has been made .
