3. Thermostat Calibration Section
Each control typically operates a pair of burners with a Snap action, Electric or Solid State. The controls were
set at the factory. However, if the griddle’s surface temperature varies greatly from the setting on the
thermostat knob, adjust the thermostat using the following procedure:
3.1. Snap Action and Electric Thermostat
1 Light pilots as described in section(s) 2.1.1 and
2.1.2.
2 Turn all the control knobs to the desired
temperature setting.
3 Wait 30 minutes (or 1 hour if griddle was cold)
for surface to stabilize.
4 Place a reliable Griddle surface thermometer, or
test instrument thermocouple, able to register
300°F (149°C), in the location above the
thermostat being calibrated as described in
section 2.2.2. Check the temperature every 5
minutes until the temperature stabilizes and
does not change by more than 30°F (16.5°C) over a 15 minute span. Figure 9
5 If the average temperature over any burner set is not within +/-15°F (8.3°C) of the knob setting, adjust the
corresponding thermostat. This is done by removing the knob, holding the thermostat knob stem, see
Figure 9, (do not allow the stem to turn or the temperature setting will not be accurate), then turn the
adjustment screw located within the center of the stem in small increments. Turn this screw counter
clockwise to increase the temperature, and clockwise to decrease the temperature.
6 Check the temperature after 15 minutes and repeat adjustment as needed until the correct temperature is
indication on the measuring instrument.
NOTE:
Hold the knob firmly when loosening or tightening the 5/16” (8mm) locknut that holds the knob onto
the thermostat shaft to keep from changing temperature settings.
3.2. Solid State Thermostat
1 Light pilots as in section 2.1.1.
2 Set all the thermostat control knobs to the desired cooking temperatures.
3 Wait 30 minutes (or 1 hour if griddle was cold) for surface temperature to stabilize.
4 Place a reliable Grill surface thermometer, or test instrument thermocouple, (able to register 550°F
(288°C)), In the location above the thermostat being calibrated described in section 2.2.2.
5 Check the temperature at each location every 5 minutes, and repeat until the temperature stabilizes and
does not change by more than 20°F (11.0°C) over a 15 minute time period. You will need to remember the
average temperature for the following steps.
6 If the thermostat is not operating within 10°F (5.5°C) of the temperature set point, you may need to adjust
the control.
7 To adjust the control, carefully remove the cap on the thermostat knob, See Figure 9a, set cap aside.
8 While holding the knob, loosen the 5/16" (8mm) nut on the thermostat shaft, (DO NOT REMOVE).
9 Once the knob is loosened from the thermostat
shaft, rotate the knob so the white indicator line
of the knob is aligned with the actual
temperature that you monitored in step 5.
10 Re-tighten the 5/16" (8mm) nut while holding
the knob in position, (do not allow the stem to
turn or the temperature setting will not be
accurate).
11 Set the control to the desired temperature and
monitor as in step 5, readjust temperature
control as needed until desired temperature is
achieved.
12 Make sure the control knob is secured, replace
cap.
