Install and Level the Legs Ensure the equipment is level in all directions. Begin by tightening each leg securely. Then, as needed at each corner, rotate the adjustable foot.

Gas Piping

• Gas piping must be sized to ensure sufficient pressure and flow to meet the full-rated gas input of the equipment.
• Connection to an existing system requires that the existing system have capacity equal to or greater than the full-rated gas input of the equipment.
• Joint compound (pipe dope) should be used sparingly and only on the male threads of the pipe joints. Such compounds must be resistant to the action of liquid propane (LP) gases.

Pressure Regulator

NOTICE

• All commercial cooking equipment must have a pressure regulator on the incoming service line for safe and efficient operation.
• Prior to connecting the regulator, check the incoming line pressure. The regulator can only withstand a maximum pressure of ¹⁄₂ PSI (14″ WC). If the line pressure is beyond this limit, a step-down regulator before the regulator provided will be required.
• The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/ 2 psi (3.5 kPa)
• The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to less than 1/2 psi (3.5 kPa)
• The arrow forged into the bottom of the regulator body shows the gas flow direction, and should point downstream to the equipment.
• The regulator provided with this equipment is configured for use with natural gas. Following the instructions in the LP Conversion Kit, it can be reconfigured for use with LP gas.
• The equipment comes fitted with a¾” N.P.T. male adapter for connection to the pressure regulator.
• Check the pressure of the incoming gas line. The regulator can withstand a maximum pressure of 14″ WC (¹⁄₂ PSI). If the line pressure is beyond this limit, a step-down regulator will be required.

2. To light the pilot burners, hold a flame source over the desired pilot burner while slowly turning its control valve screw counterclockwise, adjusting the flame to the desired intensity. Repeat for all pilot burners.

Test the Main Burners

After lighting all of the pilot burners, ensure that each main burner functions correctly.

After the lighting the pilots, the main burners can be ignited by pushing and turning the control knob from the “off” position to the desired setting. Visually check that the pilot light ignites the main burner.

The main burners can be extinguished by turning the control knob back to the “off” position. The pilot lights can be extinguished by shutting off the gas supply at the shut-off valve installed on the gas line.

FEATURES AND CONTROLS

• A Grill Grates. Angle can be adjusted.
• Gas Control Knob. Used to adjust the temperature of the grilling surface.
• Drip Tray. Collects grease and oil. This tray can be removed for cleaning. It is recommended to have a thin layer of water in the drip tray to reduce flare-ups and smoking, while still allowing plenty of volume for drippings.
• Pilot Light Access Hole. Allows access to the pilot light.
• Adjustable Foot. Used to adjust the level of the equipment.
• Leg. Supports the equipment.

BEFORE FIRST USE Setup For Lava Rock or Radiant Heat

• Lava Rock. Helps to deliver even heating across the entire surface, and also serve to collect drippings and to provide some smoke flavoring to the food. Should be replaced when they are no longer porous.

• Waffle Grate(s). Used with the lava rock setup.

• Lava Rock Cover(s). Used with the lava rock setup.
  NOTICE: Used for heavy duty models only to replace heavy duty radiants.
  NOTICE: Lava rock kits can be purchased separately as an accessory.

• Radiant Cover(s). Used alone in the radiant setup to protect the burner(s) and to help distribute the heat from the burner(s).

NOTICE: Can be left in place for medium duty models.

Convert to Radiant Heat

1. Remove the lava rock and save for future reuse.
2. Remove the waffle grate(s) and save for future reuse if still sufficiently porous; otherwise, discard.
3. Remove the lava rock cover(s) and save for future reuse.
4. Place the radiant cover(s) over the burner tube(s).

Convert to Lava Rock

1. Remove the radiant cover(s) and save for future reuse.
2. Place the lava rock cover(s) over the burner tube(s).
3. Set the waffle grate(s) into place.
4. Set the lava rock onto the waffle grate(s) and spread out evenly.

Burn-In the Equipment

1. Rotate the gas control knob(s) to the maximum setting.

2. Allow charbroiler to heat and burn-in for approximately 30 minutes.
   NOTICE: You may notice smoking during this initial burn-in; this is normal.

3. Rotate the gas control knobs to OFF.

Seasoning Grill Grates

1. Allow the charbroiler to cool or heat to a warming temperature of approximately 200° F.
2. Rub cooking oil, shortening, beef suet, or the like on the charbroiler grates with a clean cloth.
3. Heat the charbroiler to medium high and allow it to operate for approximately 30 minutes.
4. Adjust the burner dial(s) to the lowest setting and allow the charbroiler to cool and stabilize at a low heat.
5. Remove any excess oil and wipe clean.
6. Repeat the process; oil, heat for 30 minutes, cool, and wipe clean.

OPERATION

WARNING Fire, Death Hazard If you smell gas follow the instructions provided by the gas supplier. Do not touch any electrical switches; do not try to light the burner; do not use a telephone in close proximity.

CAUTION Burn Hazard Hot surfaces and food can burn skin. Allow the hot surfaces to cool before handling. Do not drop or spill water onto the cooking surface as it can spray or splatter.

TIP: Set the grill grates at an angle. This will enable liquids to run down the grates and into the drip tray, which will reduce flare-ups.

1. Verify the drip tray is in place. Add water to the drip tray. Water vapor rising from the drip tray and through the combustion chamber will help to reduce flare-ups.
2. Lightly oil and wipe the grates clean to remove any contaminants that may have accumulated or have seeped from the grill and/or perimeter since last use and to ensure a clean non-stick cooking surface.
3. Rotate the gas control knobs to ignite the main burner(s). Adjust the knob(s) to the desired heat level.
4. Preheat the grill grates for 15 minutes.
5. Cook the food.
6. Empty the drip tray periodically to ensure it does not overflow. Check the drip tray frequently and add water as necessary.
7. Do not allow oil or grease to build up on the grill grates. Wipe down the grill grates to prevent carbon build-up, which could affect the performance of the grill.

Adjusting the Pilot Light From time to time the pilot light intensity may need to be adjusted to properly ignite the main burners.

1. With the pilot light ignited, use a flathead screwdriver to turn the exposed slotted brass screw. Turn the screw clockwise to decrease intensity and counter-clockwise to increase intensity.
2. Determine the proper intensity to ignite the burner flames. Burners should ignite from pilot in under 4 seconds.

CLEANING

CAUTION Burn Hazard Hot surfaces and food can burn skin. Allow the hot surfaces to cool before handling. Do not drop or spill water onto the cooking surface as it can spray or splatter.

To prevent flare-ups and to maintain the appearance and increase the service life, clean your equipment daily.

NOTICE: Do not clean the equipment with steel wool.

NOTICE: Do not use cleaning chemicals or soaps as these can be absorbed by the cooking surface and affect the flavor of the food. If necessary, use only clean water, oil, and/or a food grade degreaser for the cleaning process.

NOTICE: To prevent corrosion, do not allow the grate(s) to remain unseasoned or without a thin coating of cooking oil.

Daily

1. While the grates are hot (approximately 300° F), use a grill brush or grill brick to scrub them clean.
2. Inspect the grates and determine if they need to be re-seasoned. If they grates do not need seasoning, apply a thin coat of cooking oil to the grates to prevent corrosion.
3. Allow the charbroiler to cool.
4. Remove, empty, and clean the drip tray.
5. Clean the exterior of the unit.

Weekly Or More Often if Needed Radiant Bars

1. Remove the radiant bars.

2. Inspect for wear. If bars are worn, order replacements.
   NOTICE: Do not operate the charbroiler with worn radiant bars. This will reduce performance of the charbroiler and may cause flare-ups.

3. Wash the radiant bars in a solution of warm, soapy water.

4. Thoroughly dry the radiant bars.

5. Place the radiant bars in the charbroiler.

Lava Rock

1. Flip over the lava rocks. This will enable any grease that has accumulated on the top of the rocks to burn off.

2. Inspect the waffle grate for wear. If the grate is worn, order a replacement.
   NOTICE: Do not operate the charbroiler with a worn grate. This will reduce the performance of the charbroiler and may cause flare-ups.

3. Inspect the rocks for wear. Vollrath recommends replacing the rocks when the surface is no longer porous. Eventually, ash and contaminants will plug the holes and the lava rock will no longer capture the drippings and convert them to smoke. Instead, the drippings will run off and risk a flare-up.
