Incogneeto™ Installation Best Practices

Important Characteristics of Natural Stone

Stone is a natural material with random natural defects in any given piece. Cracking can occur due to these defects alone.

Moreover, cracks can occur when pre-existing weak points are subjected to additional stresses or forces. Mechanical

forces caused by poor support, joints in the support structure that shi, and weight distribution will cause excess stress

on the stone. Heat dierentials that cause one portion of the stone to try to expand while other portions try to remain

xed will cause excess stress. is localized heating can come from a number of sources:

a. Heat lamps above the stone

b. Heat generated by equipment below the stone

c. Heat from hot items placed on top of the stone

In extensive testing conduction by CookTek, no natural stone was found to interfere with the performance of the wireless

communications, or absorb excess heat from the electromagnetic induction waves associated with its Incogneeto™ and

Magneeto 2™ equipment.

Design Considerations When Using Incogneeto™

• Any temperature gain that occurs inside the cabinet where an Incogneeto™ is mounted contributes to heating the

stone. Keeping the inside of the cabinets as close to room temperature as possible will therefore reduce stress on the

stone. Cabinets with poor or insucient ventilation will increase the stress on the stone.

• Tensile strength of natural stone is proportional linear with thickness: 20 mm stone is ⅓thinner than 30 mm stone



so that resistance to cracking is also reduced by ⅓ Applications with prolonged intensive use are better served with

30 mm stone above Incogneeto™ units.

• 30 mm thick natural stone dissipates heat much better than 20 mm, resulting in lower maximum temperatures. For

prolonged intensive use application, thicker stone is more durable.

• e stone is not generally heated by the induction waves, but some heating will occur from radiation back from a hot

pan. e stone around the portion that is heated from radiation provides the mechanical strength “buer” to help

prevent fractures. Allowing as much stone around the edge of the Incogneeto™ as possible will improve the strength

of the whole system.

Best Practices Design Guidelines for Installation Under Natural Stone

It is recommended that natural stone over the Incogneeto™ be 30 mm thick in high-use applications. Synthetic or

“engineered stone” at 20 mm is acceptable over the Incogneeto™ in all applications. (Note: 20 mm tops in any material

also require plywood substrate.) It is further recommended that cabinets be built with sucient ventilation to keep the

interior compartment as close to room temperature as possible.

At least 8 inches (203 mm) of additional stone surface should be allowed from the edge of the Incogneeto™ location to the

nal edge of any piece of stone. Extra care should be taken to not have mechanical seams in the cabinet support near the

Incogneeto™. Additionally, care should be taken when using heat lamps above Incogneeto units as they can damage the

Magneeto trivets when a pan is not in place to absorb the energy.

COOKTEK BY TURBOCHEF Incogneeto™ Installation Instructions Measure the countertop thickness where the unit will be installed (Figure 1). The top of the unit must be 38 to 42 mm (1.5” to 1.65") from the top of the counter. Figure 1: Measuring the Countertop Thickness Mounting the Unit The unit mounts in a square frame (supplied) underneath the counter. The frame is screwed into plywood, or narrow plywood strips (1¼" (30 mm) countertop thickness only), which are glued onto the stone, or stone’s backing.

Installing the Unit Attach the mounting frame to the wood sheet or strips with ½" wood screws. Make sure the frame is mounted square as shown in Figure 5. Next, snap the Incogneeto™ unit into place (Figure 6.) For assistance, call 1.800.908.
