Installation
The Incogneeto™ can be used with natural stone or “engineered stone” (crushed stone and polymer resin composite). It is not
recommended for use with “solid surfaces” (all polymer resin).
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.
Heat differentials that cause one portion of the stone to try to expand while other portions try to remain fixed, will cause excess stress.
This 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,
NO NATURAL STONE
was found to interfere with the performance of the wireless communications, or absorb
excess heat from the electro-magnetic induction waves associated with its Incogneeto™ and Magneeto™ II equipment.
Design Considerations When Using Incogneeto™with NATURAL STONE
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
insufficient ventilation will increase the stress on the stone. Tensile strength of natural stone is proportionately linear with thickness: 3/4”
(2.0cm) stone is 1/3rd thinner than 1-1/4” (3.0cm) stone, so that resistance to cracking is also reduced by 1/3. Applications with
prolonged intensive use are better served with 30mm stone above Incogneeto™ units. 1-1/4” (3.0cm) thick natural stone dissipates heat
much better than 3/4” (2.0cm), resulting in lower maximum temperatures. For prolonged intensive use applications, thicker stone is more
durable. The stone is not generally heated by the induction waves, but some heating will occur from radiation back from a hot pan. The
stone around the portion that is heated from radiation provides the mechanical strength “buffer” 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 1-1/4” (30mm) thick in high use applications. Synthetic or “engineered
stone” at 3/4” (2.cmm) is perfectly acceptable over the Incogneeto™ in all applications. (Note: 3/4” [2.0cm] tops in any material also
require plywood substrate.) It is further recommended that cabinets be built with sufficient ventilation to keep the interior compartment as
close to room temperature as possible. At least 8” of additional stone surface should be allowed from the edge of the Incogneeto™
location to the final edge of any piece of natural stone. This requirement is NOT necessary for use with engineered stone. Extra care
should be taken to not have a mechanical seam in the cabinet support above or close to the Incogneeto™.
General Guidelines
Note
: With engineered stone, none of these extra guidelines apply, as it is a much more uniform and generally stronger material.
Heat lamps should not be used above any Incogneeto™ units, unless they are interlocked to prevent heating when a pan is not present,
or damage to the disk may occur. Installation is only recommended under three countertop configurations:
1-1/4” (3.0cm) stone, with 1/2” (1.2cm) substrate; or 1-1/4” (3.0cm) stone with 3/4” (2.0cm) plywood strips; or 3/4” (2.0cm) stone with 3/4”
(2.0cm) substrate.
Countertop Preparation
(3.8cm - 4.2cm)
1-1/2”– 1-5/8”
(3.8cm - 4.2cm)
1-1/2”– 1-5/8”
(3.8cm - 4.2cm)
1-1/2”– 1-5/8”
The combined thickness of stone, wood and any air
gap MUST BE WITHIN A RANGE OF 1-1/2” to 1-5/8”
(3.8cm to 4.2cm). Too far away, communications
between the Magneeto II disk and Incogneeto may fail,
and/or insufficient thermal energy will be delivered to
the pan. Too close and too much energy could be
delivered resulting in damage the electronics in the
Magneeto II disk. Metals should NOT be used in any
part of the countertop construction directly above an
installed Incogneeto unit, although trace metals in the
stone or engineered stone ARE permissible. Metals in
cabinet construction may heat and / or interfere with
communication between the Magneeto II and
Incogneeto.
