Performance
The Warmset system is a self-contained heating mat, designed for use em-
bedded in a layer of self-leveling compound and/or thin set. It consists of a
thin heating ribbon tted onto a mesh.
Although the mesh is designed to be cut in order to facilitate installation
around objects and corners, it is important to note :
The heating ribbon cannot be cut.
This includes shorting the lengths to t, or splicing two lengths together.
All Warmset products must be installed by knowledgeable and qualied
persons. An intermediate skill level in electrical wiring is required. Although
Warmset products may be installed by any qualied person (pending local
codes), it is recommended that a certied and licensed electrician roughs in
the power supply wiring.
Please check and adhere to all local codes as they may require all or part of
the installation to be performed by a licensed electrician.
With electric radiant oor heating, performance is never guaranteed. Warm-
set is designed to deliver the performance listed in the above specications
section. The attainable ooring temperature is dependent on the type of
oor, and the overall thermal drain of the oor.
Thorough Insulation is recommended for optimal performance.
Warning Under no circumstance should the heating ribbon be cut, pierced, or
held in place through the use of staples. Only the mesh can be stapled.

Never install Warmset mat under carpet, wood, vinyl, or other non-masonry
ooring without embedding it in self-leveling mortar, thin-set or thick-set.
Never install Warmset mat in adhesives or glues intended for vinyl tile or
other laminate ooring, or in pre-mix mortars. It must be embedded in
polymer-modied, cement-based mortar.
Never install Warmset mat under built-ins such as cabinets or vanities or
where air does not ow freely. Heating mats installed under built-ins such as
cabinets or vanities, or in small closets, can cause dangerous levels of heat
build-up.
Never connect the Warmset mat to the thermostat before the installation is
completed.
Never use sharp tools or power tools to clean grout lines. Cleaning grout
lines with sharp tools or power tools may damage the heating ribbon and
will void the Warmset Warranty.
Never cut the heating ribbon. If the heating ribbon is cut, it can cause
electric shock, dangerous over-heating, or re. If necessary, the cold leads
may be cut shorter, but never remove them completely from the heating
ribbon.
Never use metal penetrative fasteners such as nails, staples or screws to
secure the heating ribbon to the suboor. Only the mesh can be stapled and
not the heating ribbon.
Never try to create a larger heating mat by splicing one heating mat to
another. Multiple mat cold leads must be connected in parallel.
Never install Warmset mats in walls or ceilings.
Never remove any labeling from Warmset mats. Make sure all appropriate
labels are visible for inspection.
Never install Warmset mats near other heat sources such as light xtures
and chimneys or other ammable devices.

Warmset is an electrical product. The appropriate precautions and
care that are associated with electrical installations should be taken.
Always be aware of risks of electric shock, re, and/or injury to
persons. Please read carefully and observe all precautions listed in
these pages.

Caution
Always install a Class “A” GFCI or EGFPD circuit breaker with each Warmset
mat installation. Note: All Warmset thermostats come equipped with a built-
in Class “A” GFCI or EGFPD.
Always use caution when working with tools around Warmset mats. Be
careful not to nick or cut the heating ribbon.
Always completely embed Warmset mats in minimum 3/8”self-leveling
compound and thinset mortar, or other polymer-modied, cement-based
mortar.
Always adhere to all power limitations of the breaker, thermostat, and
chosen Warmset Mat. Be sure the Voltage and Current are appropriate for the
system.
Always install Warmset mats on a dedicated 20 A circuit.
Always make sure all electrical work is done by qualied people in
accordance with local electrical and building codes.
Always use copper wiring to complete the connections in the Warmset
system.
Always seek help or clarity if problems arise. If in doubt about any
installation procedures, or if the product appears to be damaged, please
contact Warmset before starting the installation process.
All Installations must be performed by qualied personnel
in accordance with all local regulations and building codes.
Thoroughly read and follow the installation instructions and
warnings before beginning installation.
Failure to do so can result in electric shock, re, property
damage, personal injury, and/or death.
Always

01 Before Beginning
In many applications, Warmset mats can be used as primary heat.
When installing Warmset mat systems, the local environment and
desired results should be considered.
Consider how much heat will be needed to counteract the heat loss
of the space, and try to insulate as effectively as possible.
Make a sketch of the room including all appropriate measurements. These
measurements should be made from wall to wall. Measurements should in-
clude the location and size of major obstacles and installations such as cab-
inets, bathtubs, toilets, etc. Determine the total area to be covered by the
Warmset mat by subtracting the area covered by these built-ins from the total
area of the room.
When planning your installation, consider the following:
Heat will not radiate well beyond roughly 1-1/2” on either side of the
heating ribbon. To avoid cold-spots, consistent coverage is important.
Heating ribbon must not be installed within 2” of a built-in such as a counter
or vanity.
Be sure not to install heating ribbon underneath cabinets or furniture
with no oor clearance. Excessive heat build-up can cause damage.
Do not place the heating ribbon within 4” of other wiring or piping.
When placing heating ribbon, be sure it will not be covered by trim.
The heating ribbon must be completely embedded in self-leveling com-
pound and thinset. Only power leads may exit.
All Warmset Mat mats have a width of 20”.
A gap of 4 to 6”around the edges of the oor should be maintained. This gap is
accounted for by calculating 90% of the total measured square footage. To nd
this value, simply multiply the total square footage found in part 1.1 by 0.9. Use
this result to determine the required Warmset mat sizes for the project.
