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 dierentials 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 insucient ventilation will increase the stress on the stone.
• Tensile strength of natural stone is proportional linear with thickness: 20 mm stone is ⅓thinner 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 “buer” 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 sucient 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.
