Frequently Asked Questions - GGHDM-72 Vollrath

How do I light the griddle plate?

First, open the manual shut-off valve. Wait 5 minutes to allow any gas to dissipate. Hold a flame over the desired burner and turn the pilot adjustment screw counterclockwise to light it. Then, push and turn the main burner control knob from the Off position to the desired setting.

What is the daily cleaning procedure?

Leave the plate hot, use a grill brush or griddle brick to remove carbonized deposits. Remove, empty, and clean the drip pan. Clean the exterior of the appliance. Turn off and let cool, then apply a thin film of cooking oil to prevent corrosion.

How do I season the plate after cleaning?

Apply food-grade oil, solid vegetable shortening, or beef tallow to the hot plate. Heat at medium-high temperature for 30 minutes. Allow to cool, wipe off excess. Repeat a second time.

What should I do if I smell gas?

Immediately close the gas supply valve. Ventilate the area. Do not operate any electrical switches, light any flames, or use a phone nearby. Call a qualified service agent.

What type of gas should I use?

The appliance is factory-set for natural gas (heating value 1,035 BTU/ft³). It can be converted to liquid propane (LP) using the supplied conversion kit by a qualified technician.

How do I adjust the pilot?

The pilot should light the main burner within 4 seconds. Use a flat-head screwdriver to turn the slotted copper screw: clockwise to decrease intensity, counterclockwise to increase.

What is the required safety clearance around the appliance?

At least 6 inches (15 cm) of space must be maintained on all sides, especially at the rear, to ensure proper ventilation and prevent overheating.

Can I use soapy water to clean the cooking surface?

No. Soapy water can cause corrosion of the plate surface. Use only clean water, oil, and/or a food-safe degreaser. For the controls and sides, a cloth dampened with soapy water is acceptable.

Where can I find replacement parts?

Spare parts are available on the Vollrath.com website. For any repairs, contact Vollrath technical services at the numbers listed in the manual.

What should I do if the surface heats unevenly?

First, check that the rear clearance is at least 6 inches. If the problem persists, the air shutter adjustment may be incorrect. Contact Vollrath technical support for assistance.
