4. Allow the oven, or appliance, to heat and the thermostat
to cycle three times. After sufficient time, check the
temperature, if the temperature does not read with in
±20° of the dial setting,
re-calibrate as follows:
5. Pull the dial straight off without turning the thermostat
shaft.
6. Hold the calibration plate and loosen the two calibration
screws until the plate can be moved independently of the
control.
7. Turn the calibration plate so that the instrument of the
thermometer reading is in line with the indicator mark.
Hold the plate and tighten the screws firmly.
8. Replace the dial.
9. Note: If the above adjustment is prevented by the two
loosened calibration lock screws being in contact with
the ends of the screw clearance plate to the proper
location, reassemble the screws in the other tapped holes
designed for them.
If the thermostat is cycling beyond the 20° tolerance and the
appliance is under warranty
re-calibrate the thermostat
or
if not under warranty consult the owner for proper action.
If the thermostat is out of calibration more than fifty (50)
degrees, it will not like hold an attempt of re-calibration, we
suggest that the thermostat be replaced.

The Robertshaw UN throttle-type griddle control requires a
by-pass adjustment. To adjust, proceed as follows:
1. Be sure that the pilot flames are lit and adjusted.
2. Turn the dial to 200°F (93°C) mark and allow the griddle
to heat for approximately 5 minutes.
3. Turn the dial clockwise to “LOW” position. The control will
cut down to the BY-PASS flame.
4. Carefully remove the dial, making sure the setting is not
disturbed.
5. With a screwdriver, turn the by-pass adjustment screw
and adjust to the “LOWEST POSSIBLE STABLE FLAME
COVERING THE ENTIRE BURNER”. Turn the screw clockwise
to decrease or counter-clockwise to increase the size of
the by-pass flame.
6. Replace the dial.
7. Turn the dial to the “OFF” position.
Re calibration
Do not re-calibrate until the following has been checked:
1. BY-PASS FLAME for proper adjustment (see above).
2 Check that the control bulb is fully inserted into the bulb
tube.
To check calibration, proceed as follows:
Use a Robertshaw test instrument with a special disc type
thermocouple or a reliable “SURFACE” TYPE thermometer.
(Note: A drop of oil on the face of the disc will provide better
contact.
