Part # 138683 (01/08) Page 193. Continue to monitor the oven temperature, recordingthe readings at 5 minute intervals until three successivereadings are within 5°F, (2°C), of each other.If the temperature does not read within 15°F, (8°C), of the dialsetting, recalibrate as follows.1. Remove the oven temperature control dial, making surethe setting is not disturbed.2. Hold the calibration plate, (located directly behind thecontrol dial), and loosen the two calibration lock screwsuntil the plate can be rotated independently of thecontrol.3. Turn the calibration plate until the temperature indicatedon the plate corresponds with the reading on the testinstrument. Hold the plate in place and tighten thescrews firmly.4. Repeat step 3 in the previous section, checking thetemperature to ensure the adjustment has been madeproperly.5. Replace the temperature control dial.NOTE: If adjustment of the calibration plate is prevented bythe position of the lock screws, the screws can be moved toother holes that have been tapped for them.BJWA Griddle Thermostat(H/P 280 Series Only)When the griddle surface reaches the temperature for whichthe dial is set the control cuts down the flow of gas to theamount required to keep the griddle at that temperature.The control must be adjusted to pass enough gas to keep theentire burner ignited. To properly adjust the by-pass setting,proceed as follows:1. Light the burner by turning the dial fully “ON.”2. After 5 minutes, turn the dial clockwise to a point slightlypast, (to the right of), the first mark on the dial.3. Remove the dial by pulling it straight off.4. With a screwdriver, turn the by-pass adjustment screwcounter-clockwise to decrease the flame, or clockwise toincrease the flame, until there is a minimum flame alongthe entire burner.CALIBRATIONSCREWBY-PASSADJUSTMENTSCREWROBERTSHAW BJWATHERMOSTATCalibration1. Use a Robertshaw test instrument with a disc-typethermocouple, or a reliable “surface” type thermometer.(NOTE: A drop of oil on the face of the disc will provide forbetter contact.)2. Turn ALL griddle control dials to 400°F, (240°C). allow thetemperature to stabilize by waiting for the thermostat(s)to cycle three times before taking a temperature reading.3. Check the temperature reading when the control cutsdown to by-pass, by placing the sensor firmly on thegriddle surface directly above the sensing bulb of thecontrol. Test instrument should read from 350° to 410°F,(196° to 213°C). If the dial setting does not agree withthe test instrument reading within the above limits,recalibrate.NOTE: NO ATTEMPT SHOULD BE MADE TO RECALIBRATETHE GRIDDLE CONTROL WITHIN THE WARRANTY PERIOD IFTHE TEMPERATURE IS WITHIN ±20°F OF THE DIAL SETTING.RECALIBRATION SHOULD BE PERFORMED IF THE CONTROL ISFOUND TO BE INACCURATE BY MORE THAN ±20°F, AND LESSTHAN ±50°F. IF THE CONTROL IS FOUND TO BE INACCURATEBY MORE THAN ±50°F DURING THE WARRANTY PERIOD, THECONTROL WILL BE REPLACED UNDER WARRANTY.To recalibrate:1. Remove the dial and push out the center metal insert.2. Replace the dial without the insert.3. Holding the dial firmly in place, insert a screwdriverthrough the center of the dial and seat it in the slot inthe calibration screw. DO NOT TURN THIS SCREW! Exertpressure on the screwdriver to push the calibration steminward.ADJUSTMENTS Continued
