ADJUSTMENT OF BYPASS (MINIMUM BURNER) FLAME

This is the flame which must be maintained on theburners when the Fry Top has reached the temperature set on

the dial. Enough gas must be bypassed by the control to keepthe entire burner lit. The thermostat regulates the flamefrom high to low in accoraance with the Fry Top temperatureand will automatically turn down to this bypass flame whenthe temperature set on the dial is attained.

Special care should be taken to see that the thermostat

bulb is in its proper place and no part of the capillary tubeis in any flame or heat zone. The Fry Top plate should neverbe removed without first removing the thermostat bulb(s) frombeneath the plate. Never allow capillary tube to be kinked orcrushed.

THE BYPASS MUST BE SET CAREFULLY AND ACCURATELY ASFOLLOWS:

1. Light burners and turn Dial (A) counterclockwise and toa point midway between the "Gas On" mark and the nextgradutation to the right of it (shown by "X"). If theburner goes out entirely, the bypass is closed.

2. Slip off Dial (A). Remove the valve panel from the frontof the range.

3. with a screwdriver, turn bypass adjustor (8). Turning itout counterclockwise increases the bypass flame; turningit in clockwise decreases the bypass flame. Adjust untilthere is a flame approximately lIS" high over the entireburner.

4. Replace dial, rotating dial clockwise until it snapsinto its original position.

5. Reinstall the valve panel on front of the range.

FRY TOP THERMOSTAT CALIBRATION CHECK:

The Fry Top temperature should be che:ked or re:ali-orated with the Fry Top hot. NOTE: See "Adjustment of Bypass(Minimum Burner) Flame" before recalibrating this thermostat.

HOT CHECK METHOD:

1. Place reliable thermometer in cente: of the top of theFry Top over the thermal bulb.

2. Set Dial (A) to 350' F.

3. Wait until temperatu:e rises and remains constant.

4. If dial does not agree with thermometer readings, slipoff Dial (A) and push out metal insert.

5. Replace dial, turn to 350' F mark.

6. Hold dial firmly, insert screwdriver through center ofdial and push calibration stem (C) inward. DO NOT TURNTHIS STEM.

OVEN THERMOSTAT

The Model BJ Robertshaw is a combination thermostat and

gas valve. The gas is turned on and the temperature settingis made by a single rotation of the dial. This valveautomatically locks itself in the "OFF" position. To use,push dial inward, rotate counterclockwise to the desiredtemperature. To shut gas off, rotate clOckwise to "OFF"position.

This thermostat is a precision instrument carefully madeand properly calibrated (i.e. the' dial is properly set) atthe factory to control temperatures accurately. It shouldcontrol temperatures for the proper cooking of food withoutrecalibration. The calibration of this thermostat should not

be changed until considerable experience with cooking resultshas definitely proved that the thermostat is not maintainingthe proper temperature.

THE RECALIBRATION SHOULD NOT BE MADE UNTIL THE BYPASS(MINIMUM BURNER) FLAME HAS BEEN PROPERLY ADJUSTED.

ADJUSTMENT OF BYPASS (MINIMUM BURNER) FLAME

This is the flame that must be maintained on the burnerswhen the oven has come up to the temperature set on the dial.

Enough gas must be bypassed by the control to keep the entireburner lit. The thermostat regulates the flame from high tolow in accordance with the oven temperature and will auto-

matically turn down to this bypass flame when the tempera-tures set on the dial is attained in the oven.

The oven temperature should be checked or recalibratedwith oven hot. NOTE: see "Adjustment of Bypass (MinimuiTIBurner) Flame" above before recalibrating this thermostat.

HOT CHECK METHOD:

1. Place reliable thermometer in center of oven.

2. Set Dial (A) at 350· F.

3. Wait until temperature rises and remains constant.

4. If dial noes not agree with thermometer readings, slipoff Dial (A) and push out metal insert.
