COMMERCIAL FOOD SERVICE

General Requirements

• •Adequate support is required directly underneath any load. The stone should not be used to transfer any bending and/or shear loads from external equipment to supporting structures.
• •Must accommodate expansion and contraction to minimize the buildup of any mechanical and thermal stresses.
• •All external loads must be limited to compressive loads. Compressive loads should never exceed the limits as provided in the EuroStone Technical Specifications.
• •EuroStone must be insulated from heated food service equipment.
• •Provide adequate distance between the material and any adjacent walls and/or cabinets or any other possible constraint. We recommend a minimum of 1/8" clearance between the surface and any columns or brackets that penetrate through the material.

Support Drawing

Notes

• •Flexible expansion joints are highly recommended. In the event these joints are not acceptable to the end user, a minimum of 3 layers of Nomex insulation are required.
• •All underlayment support materials should be moisture resistant.
• •If shimming is required, shim from below the underlayment and not between the underlayment and the stone.

Food Service Hot & Cold Cutouts

• •Provide a minimum 1/4" radius on inside corners of cutouts.
• •Ease all top and bottom edges.
• •Cutouts must be at least 6" apart.
• •Smooth the entire interior of the cutout to remove any chatter or chipping. Use a minimum of 120 grit diamond.
• •Provide space for insulating materials and extra equipment support. Always isolate the weight of a drop-in food well with additional supports.
• •Use a minimum of two (2) layers of Nomex insulation as referenced in General Requirements. Affix the Nomex insulation with a minimum 4ml aluminum tape, ensuring that the tape does not create a direct heat transfer to the stone.
• •Provide a minimum 1/8" gap between the appliance and the edge of the cutout to allow for expansion and/or contraction.
• •Support materials (underlayment) should be moisture resistant.
• •All deck (surface) seams require structural support. The structural support should be flush with the supporting substrate. If shimming is required, shim from below the underlayment, not the stone.
• •Hot & Cold Wells should be separated by a minimum of 12" between cutouts.
• •Do not undermount in any manner which causes the stone to become part of the tray.

Surface Seams

• •Surface seams should be flexible expansion joints a minimum of 1/8" filled with 100% silicone (highly recommended).
• •Cover strips such as "T" molding may be used to cover expansion seams.
• •Hard seams are acceptable if the stone is insulated with a minimum of three (3) layers of Nomex insulation.
• •Avoid seams through cutouts or inside corners.

Heat Lamps

• •Do not attach heat lamps directly to stone; attach to the supporting structure.
• •Drill through the material and attach the heat lamp to the support structure below.
• •Provide minimum 1/8" radial clearance between the stone and any columns or brackets penetrating the material.
• •Do not create any hot spots on the stone by focusing the heat lamp only on a particular section. Provide uniform heat across the entire surface of the stone.

Sneeze Guards

• •Mount sneeze guards directly to the support structure.
• •Do not attach sneeze guards directly to the stone.
• •Provide minimum 1/8" radial clearance between the stone and any columns or brackets penetrating the material.
