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. Calibration Procedures
3.1.1. 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.
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 picture above, (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.
NOTICE
The adjustment screw on the thermostat is sealed by the Manufacturer to protect the calibration. It may be
necessary to remove this seal to be able to adjust the thermostat.
3.1.2. Solid State Thermostat
1. Light pilots as in section 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 Grill surface thermometer,
or test instrument thermocouple, able to register
300°F (149°C), in the location above the
thermostat being calibrated 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 time period. You will need to remember the average
temperature for the next step.
5. Carefully remove the cap on the thermostat knob with the white indicator line see picture this section. While
holding the knob, loosen the 5/16" (8 mm) nut on the thermostat shaft, (DO NOT REMOVE), once the nut is loose
the knob can be rotated so that the cap line marker is aligned with the actual temperature that the Grill surface
thermometer is indicating.
6. 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). Replace cap.
