Frequently Asked Questions - HEG72E Vulcan

Why won't the griddle heat up (indicator light off)?

Check the main power supply and circuit breakers. Ensure the thermostat is set above 300°F. If the indicator light does not glow, the thermostat may be faulty. Refer to the thermostat replacement procedure in the service manual.

Why does the griddle heat up but the indicator light stays on?

If the indicator light is on but the griddle does not heat, the heating elements may be inoperative. Check voltage to the elements and replace if necessary. See heating element replacement instructions.

How do I calibrate the thermostat?

Place a surface temperature probe in the center of the thermostat's sensing area. Set the thermostat to 350°F and allow three cycles. Note the on/off temperatures. If the average is within 15°F of the set point, it's calibrated. If not, remove the knob and adjust the calibration screw (1/4 turn = 18°F change). Recheck and reseal with nail polish.

What causes hot and cold spots on the griddle?

Possible causes include uneven loading of food, heating elements not clamped tightly to the griddle plate, incorrect voltage elements, or air drafts. Ensure elements are torqued to 30-35 inch-pounds and the thermostat bulb is flush against the plate.

Why does the grease smoke excessively?

The temperature may be set too high. Also, moisture in food can turn to steam. Reduce the thermostat setting or allow the griddle to stabilize. Clean the surface if residue is burning.

How often should I clean the griddle?

Daily cleaning is recommended to prevent gum build-up. Follow the cleaning procedures in the Installation and Owners Manual. Use a griddle stone or mild cleaner; avoid abrasive pads that may damage the surface.

Can I replace the heating element myself?

This procedure should be performed by a trained Vulcan service technician. It involves disconnecting power, lifting the griddle plate, and removing the element pressure plate. Torque nuts to 30-35 inch-pounds and use anti-seize compound.

What does the indicator light mean?

The red indicator light energizes when the thermostat calls for heat and de-energizes when the set temperature is reached. It cycles during cooking to maintain temperature.

What is the recommended voltage for the HEG72E?

The griddle can be configured for 208V, 240V, or 480V, single or three phase. The total power is 32.4 kW, requiring two separate fused branch circuits. Refer to the wiring diagrams for proper connections.

How do I lift the griddle plate for service?

Remove thermostat knobs and front trim panel. Unbolt the griddle plate from each side. Lift straight up and place two 4x4 blocks between the plate and the unit sides, about 6-7 inches high. Ensure the grease chute does not raise past the heater panel.

SERVICE PROCEDURES AND ADJUSTMENTS

THERMOSTAT CALIBRATION PROCEDURES

1. Clean temperature test section that is not working. Center temperature tester surface mount probe in center of thermostat probe. See table for proper testing locations according to griddle size.

NOTE: All readings taken 12" from front of griddle.

Griddle Size	Distance(s) From Left Edge of Griddle
24" 6", 18"
36" 6", 18", 30"
48" 6", 18", 30", 42"
60" 6", 18", 30", 42", 54"
72" 6", 18", 30", 42", 54", 66"

1. Set the thermostat to a temperature above 300^ F.
2. Allow the thermostat to cycle three times.
3. Note the tester reading when the indicator light turns ON and OFF.

NOTE: If the difference between the ON and OFF temperatures is greater than 25^ F, replace the thermostat.

1. Add these two temperatures together, then divide the sum by 2 to obtain an average temperature.

A. If the average temperature is within 15^ F of the set temperature, the thermostat is calibrated.
B. If the average temperature is not within 15^ F of the set temperature:

1) Remove thermostat knob.
2) Insert a flathead screwdriver into thermostat dial stem until it reaches the calibration screw.

Fig. 17

3) Turn adjustment screw CCW to increase and CW to decrease temperature.

Fig. 18

NOTE: A 1/4 turn equals 18^ F change.

1. Replace knob and repeat steps 3 and 5 until average temperature is within 15^ F of set temperature.
2. Reseal adjustment screw to prevent movement.

NOTE: Finger nail polish can be used to reseal screw to prevent movement.

1. If thermostat cannot be calibrated, replace thermostat as outlined under THERMOSTAT REPLACEMENT.

TESTING VOLTAGE TO HEATER(S)

WARNING

Disconnect the electrical power to the machine and follow lockout / tagout procedures.

1. Test supply voltage to verify it is correct.
2. Turn power off to griddle.
3. Place griddle into GRIDDLE SERVICE POSITION.
4. Connect voltmeter to leads of heating element in question.

5. Set meter on the appropriate range, determined by line voltage rating stamped on griddle data plate.

6. Turn on electrical power.

7. Turn thermostat to 350^ F.

A. Pilot light will energize.

1. Reading should agree with the voltage rating stamped on the griddle data plate.

A. If voltage reading is incorrect, and the line voltage is correct, the thermostat is not functioning properly.

B. If current draw is correct, then heating element is functioning properly. See table below for proper values.

2. The electrical connection(s) to the griddle are made in the junction box.

A. Detailed information about the electrical connections to the griddle is contained in the "Installation and Owners Manual".

1. From the junction box, one electrical connection is made to the thermostat. The other electrical connection is made to the common side of the two heating elements which the thermostat controls.

2. With the dial set to "OFF", the thermostat contacts are open.

3. Turn dial to 350^ F.

A. The thermostat contacts close, electrical power is applied to the heating elements, the griddle begins to heat.
B. The indicator light energizes.

1. When the griddle surface reaches 350^ F, the thermostat contacts open and electrical power is removed from the heating elements.

A. The indicator light de-energizes.

1. The thermostat will cycle the heating elements and indicator light to maintain the griddle temperature.

72" WIRING DIAGRAM

Notes:

1. For supply connections, use copper wire sized in accordance with the national electrical code and suitable for at least 90^ C ( 194^ F).

2. SERVICING ONLY

Each half of this griddle is wired separately and terminates in its own junction box. Each junction box requires a separate fused branch circuit power supply as the griddle is not fused. Both power sources have to be disconnected before servicing the device.

1. Lead marker numbers are the same as lead item numbers unless otherwise specified.

2. Wiring to be:

A. 10G,m 532515 - leads 1, 4, 8, 10, 11, 15 - 19, J, J2 and GRD.

B. 18GA., 532518 - leads 2 and 3.
