• B Waffle Grate(s). Used with the lava rock setup.
• C Lava Rock Cover(s). Used with the lava rock setup.
• D Radiant Cover(s). Used alone in the radiant setup to protect the burner(s) and to help to better distribute the heat from the burner(s).

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.

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 within 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 that 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 that 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.

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.

• 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.
• 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 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 grate is worn, order a replacement.
   NOTICE: Do not operate the charbroiler with a worn grate. This will reduce 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 right off and risk a flare-up.
