Technical Specifications
1. After installing your oor, use the ohmmeter to record the nal resistance measurement of the QuietWarmth
®
heated
underlayment. The resistance must be within the range of the factory recorded resistance. If not, call our customer service
number for assistance. Damage may have occurred during oor installation. Keep a record of all three resistance measures as
they will be needed for warranty purposes (See Resistance Measures Chart, pg. 7 ).
2. Install the oor sensing thermostat in the 4” square electrical box according to the installation instructions provided with the
thermostat. Connect the power mat leads, oor sensor, and power supply wiring as shown in the thermostat instructions and as
diagramed on the back of the thermostat. For general wiring diagrams, reference, Fig.4 – Control Wiring Diagram on page 4.
3. Route QuietWarmth
®
lead elements up through the electrical conduit and into the 4” square thermostat box. Wire the leads
in parallel (not series) black-black and white-white. Then wire a short “pig-tail” (of correctly sized wire for the load) over to the
thermostat. The number of conductors per connection must not exceed the amperage rating of the circuit or local or national
codes. Field wiring must be 14 gauge, Type THHN as provided with the product.
4. Use the appropriate size cover ring to mount the thermostat to the electrical box.
5. Indicate which branch circuits supply the QuietWarmth
®
heated underlayment and retain the ETL labels for each QuietWarmth
®
pad in a convenient location, ie., taped to the circuit breaker box, for reference by the electrical inspector or homeowner. Leave
one ETL label attached to the QuietWarmth
®
pad. Attached warning label #1 in a convenient location (e.g., inside of thermostat
control door) in the room where QuietWarmth
®
is installed.
6. After all thermostatic controls are installed, power up the system to briey test operation of all components.
7. Refer to instructions provided with the thermostatic controls for proper setting. Keep instructions in a safe place for future
reference.
See section 1-A.See section 1-B.
Approved Surfaces for Applications: Plywood, wood, hardboard underlayment, association grade particleboard, concrete above
grade in the absence of excessive moisture and/or excessive alkali, and well-bonded VCT* and sheet vinyl* (non-embossed and
non-cushioned). Sub-oor must meet NWFA (National Hardwood Flooring Association) and local building code standards for
quality, thickness, and maximum deection.
• 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.
• 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 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.
Use only wood ooring adhesive approved by the ooring material
manufacturer below and above the QuietWarmth
®
.
3/16”x 3/16” Square-notch or U-notch
(Use plastic trowel for heating element side if available)
• Maximum 1/4” variance in 10’.
• Must be properly prepared per NWFA specications.
• All cracks in excess of 1/16” must be lled.
• Surface must be clean, dry and free of contaminants and sealers.
1. Lay out the QuietWarmth
®
heated underlayment.
2. Except for approximately 1” of space between the walls and QuietWarmth
®
to run the lead wires, be sure to run QuietWarmth
®
to the edges of the perimeter leaving no gaps. Where necessary, use Insulayment
®
underlayment padding to ll in the gaps.
Insulayment
®
(NOT QuietWarmth
®
) can be cut to size using a sharp utility knife and a straight edge. Duct tape all seams. Do
not tape over heating wire.
3. Pull back the QuietWarmth
®
heated underlayment.
4. Apply adhesive to the suboor as per manufacturer’s instructions.
5. Lay the QuietWarmth
®
back into the adhesive.
6. Immediately (within 10 minutes) roll the QuietWarmth
®
with a 35 lb roller in diagonal directions.
7. Do not walk on the rolled areas.
8. Seams should be butted together, leaving no gaps or overlaps.
9. Allow set time as per adhesive manufacturers instructions.
10. Install wood oor as per manufacturers instructions. Take care not to damage heating element.
Leave 1/2” to 3/4” space from the wall to run lead wires.
Small gaps like this do not need to be covered by regular
(non-heated) underlayment.
* A contactor may be required for large installations.
Consult an electrician.
** Sensor can be run down the wall or in a separate conduit
from the power leads.
Locate thermostat sensor probe equally spaced between two heating wires.
Tape wire in place.

Note: if installing a programmable
thermostat, do not install an external
timer. The timer will disrupt the
programming.
If interfacing with a building energy
management system, use a non-
programmable control.

*It is acceptable to use a utility knife to notch out a
1/4” x 1” piece of the padding material to imbed the
sensor probe so it does not create a high spot.
(DO NOT CUT THE HEATING ELEMENT)
