QuietWarmth
®
is approved for indoor, dry area tile applications. Do not use in shower pan applications or areas exposed to
excessive moisture. Kitchen and bath areas that receive incidental moisture are acceptable.
The underlayment must be conditioned at 70 degrees Fahrenheit with the relative humidity between 25 and 65% for at least 24
hrs before and 72 hrs after installation.
Clean, structurally sound, underlayment grade plywood, backer board, concrete in the absence of excess moisture and/or
excessive alkali, and well bonded VCT* or sheet vinyl* (non-embossed and non-cushioned). All sub-oor structures must meet or
exceed the American National Standard Specications (ANSI) standards for quality, thickness, and maximum deection. The sub-
oor must also comply with any local building code standards.
The following is a list of sub-oor surfaces NOT suitable for tile installations, masonite, all grades of lauan plywood, expanded
polystyrene (styrofoam) insulation board, particle board, paneling, stripwood oors, grease-saturated concrete, vertically displaced
concrete, sheathing and/or other oriented strand board, pressure-treated plywood, re-resistant plywood, curing compounds, felt
paper and scribing felt.
• If at all possible, remove the old sheet vinyl or VCT. It is almost always a better choice to install over the original sub-oor
surface.
• Wood sub-oors that are structurally suitable for vinyl, may not be suitable for ceramic tile or wood oors. Double-check the sub-
oor requirements. Verify that wood oor assembly meets or exceeds requirements for ceramic tile installation under TCNA (Tile
Council of North America) and ANSI (American National Standards Institute) guidelines.
• If not removed, the vinyl must be well adhered to the sub-oor throughout the entire oor.
• If installing on top of vinyl, make sure the mortar or adhesive is approved for use on vinyl.
• Allow additional drying or “set” time (at least twice the manufacturer’s recommendation) for the setting material used in each
phase of the installation.
Floor must be clean, smooth, dry and free of foreign matter that would interfere with a good bond. Fill all cracks and depressions
with a suitable oor patch. If adhesive removal chemicals have been used, make sure the oor has been properly rinsed and all
chemical residues are removed. All existing cracks in excess of 1/16 inch must be properly repaired with appropriate materials.
All sub-oor assemblies should be tested for moisture vapor emission rates by utilizing anhydrous calcium chloride test kits
for concrete. Do not install ooring material when in excess of ooring manufacturer’s recommendations for moisture vapor
emissions.
12. Depending on the Amperage requirements of multiple QuietWarmth
®
heated underlayment pads, a relay may be required.
Consult with an electrician to determine the type and size of relay required.
1. Plan the heated area of the oor so that the desired trafc areas can be heated with a combination of the two available mat
sizes (3’x5’ and 3’x10’). When planning your heated oor area, keep the following important points in mind:
• Non-heated areas of the oor must be covered with Insulayment (for ceramic or porcelain) or QuietWalk underlayment
(for laminate, bamboo, or wood). Cut the proper underlayment to t the areas of the oor that cannot be covered by
QuietWarmth heated underlayment. This will keep your oor level.
• Do not cut QuietWarmth
®
heated underlayment.
• Do not cut or pierce QuietWarmth’s heating wires.
• Do not overlap QuietWarmth
®
heated underlayment.
• Do not duct tape over QuietWarmth’s heating wires.
• Lead wires should run along the end of the mats to the nearest wall and electrical junction box. Check local and national
codes regarding the use of conduit from the oor to the junction box. A licensed electrician must make all electrical
connections.
• Do not run lead wires over or under mats.
• Do not install QuietWarmth
®
heaters under cabinets, built-ins or furniture with a solid surface base. Excessive heat will
accumulate under these items and may damage QuietWarmth’s heating elements. IT IS IMPERATIVE FOR THE LIFE
OF YOUR QUIETWARMTH PANELS THAT YOU CREATE AN AIR GAP UNDER ANY SOLID BOTTOM FURNITURE,
FIXTURES OR OTHER ITEMS WITH THE USE OF LEGS OR SPACERS TO AVOID EXCESSIVE HEAT BUILDUP.
(Example: bookcases, trunks, etc.)
2. With all approved oor types, be sure the suboor surface is clean and dry*. The oor must be completely swept of all debris
including all nails, dirt, wood and other construction debris. Make absolutely sure there are no objects on the oor that might
damage the QuietWarmth
®
wires.

3. Before starting, remove the QuietWarmth
®
heated underlayment from the box. Attach both lead wires to a high quality digital
ohmmeter to measure the resistance. Compare the resistance you measured to the resistance range recorded by the factory
on the label attached to the padding. If the resistance is not within the range of the factory recorded resistance, call our
customer service number for assistance. Damage may have occurred during shipping. Do not proceed with the installation.
Keep a record of resistance measures as they will be needed for warranty purposes.
4. Leave the factory labels attached to the padding and the lead wires for later inspection. Save warning label #1, it must be
placed near or on the face of the thermostatic control.
1. Lay QuietWarmth
®
underlayment over the suboor with the heating wires facing up. (Photo 1)
2. Layout lead wires so they run to the nearest wall with an electrical box. ( See Fig. 2 on page 3.) Connections will be made
later. (Photo 2)
3. Allow approximately 1” of oor space between the wall and QuietWarmth
®
to run the lead wires to the conduit. Use thin strips of
duct tape to hold lead wires in place – DO NOT STAPLE.
4. Padding should be completely at, butted together ush, do not overlap the pad.
5. Tape the seams with duct tape or other water and tear resistant, utility-grade, poly-coated cloth backed tape that has a very
aggressive adhesive. (Photo 3)
6. The thermostat sensor wire should be installed on top of the QuietWarmth
®
heated underlayment and routed up the wall to the
thermostat electrical box. Place the sensor wire evenly spaced between two QuietWarmth® heating wires extending about
6”-12” into the QuietWarmth
®
heated underlayment. (Refer to Fig. 3 Sensor Wire Location on page 3.) It is acceptable to use a
utility knife to notch out a piece of the padding material to imbed the sensor wire (DO NOT CUT THE HEATING WIRE). You can
tape the sensor wire in place but do not tape over the sensor probe as this will cause heat to build up causing the thermostatic
control to reduce power to QuietWarmth
®
. Do not tape over QuietWarmth
®
heating elements.
1. When installing the oor, be careful not to damage QuietWarmth’s heating elements. If the oor covering is not immediately
installed, protect QuietWarmth
®
heated underlayment with corrugated box material or plywood.
• Keep trafc to a minimum on installed QuietWarmth
®
heated underlayment prior to oor covering installation.
• Avoid dropping, rolling or dragging objects or tools over the heating elements.
• Be careful that nails, screws or other fasteners do not penetrate the oor in the area of QuietWarmth
®
.
QuietWarmth’s heating elements can be damaged by fasteners penetrating the oor.
•Do not attempt to repair damaged heating elements.
2. Install the oating laminate or oating wood oor as per manufacturers instructions.
