SECTION 1
UNDERSTANDING EverWarm Radiant Heat FILM
Carbonic Heating Film is a revolutionary solution to today’s radiant floor
heating applications. The Heating Film is manufactured to make radiant floor
heating more readily available, far more adaptable for unique applications
and designs, and far easier to install than many other radiant floor products.
Carbonic Heating Film is 40.6 inches wide (but can be cut to half the width if
desired for certain applications) and is available in many lengths to
accommodate your specific needs. The Heating Film may be cut to any
length with the use of scissors, a razor knife, or other cutting instruments. It
can also be cut at any angle needed for each application, including the
cutting of a hole for an electrical outlet, toilet flange, or floor register.
There are a few things to know about the structure of the Heating Film.
Electrical current-conducting copper bus bars run down the length of the
Heating Film (2 bus bars are required to create heat - see drawing). Should a
copper bus bar be cut during the installation of the product, you may repair it
by either adding an “Adder” at the end or by installing a “Jumper” at the cut
point. More about these later.
Under no circumstances should the active areas (gray) of the Heating Film
be allowed to overlap itself or an adjacent piece of the Heating Film. The
product includes three areas (the two white outer edge strips and the white
center “Cut Line” strip) suitable for nailing and stapling to sub-floor, if
deemed necessary, for the designed installation of the product. These strips
are non-conductive and non-heat generating. All fasteners used to secure
the Heating Film to the sub-floor (excluding adhesives), including staples or
nails that are to be used, must only be placed through these designated
areas and not in the active carbon (gray) heating areas. Failure to do so will
cause problems with the system and/or damage the Heating Film and
associated areas including the building structure. The Heating Film can be
installed with either side facing up.

SECTION 1
EXPECTED FLOOR TEMPERATURE
Heating performance is never guaranteed. EverWarm Radiant Heat is
designed to deliver 15 W/sq. ft., with an average attainable temperature
between 75°F (23.9°C) and 104°F (40°C), depending upon the subfloor, the
layers of materials included in the floor installation, and the type of flooring
used. The attainable floor temperature is dependent on how well the floor is
insulated, the temperature of the floor prior to start up, and the overall
thermal drain of the floor mass. Insulation is recommended under the
Heating Film for best performance.
WIRING ASSEMBLIES
Since this is a high voltage product, a connection system is required for
power. A “Harness” is used to connect the Heating Film to a thermostat and
power supply, and a Harness is used to connect multiple pieces of Heating
Film in certain installations. EverWarm Radiant Heat Harnesses, Adders,
and Jumpers are manufactured for either 120V or 240V applications. The
wiring assemblies are designed for maximum efficiency and will work well
for almost any layout requirements. It is important to note that there are six
crimping terminals per sheet for the 120v Harness and four crimping
terminals per sheet for the 240v Harness.
THERE ARE THREE TYPES OF WIRING ASSEMBLIES:
1. Harnesses (J, J2, J3, J4): Harnesses
are used for connecting sheet(s) of Heating
Film with a 12 foot long “cold lead” that is
run to a thermostat, or to connect to
another sheet of Heating Film. Harnesses
are available in 120 volt and 240 volt
configurations. For a single panel 120 volt
application a “J-120” (J indicates one sheet,
and 120 is the voltage) would be required.
For a dual sheet would be required.
For a dual sheet configuration using 240 volts a “J2-240” (J2 indicates two
sheets, and 240 is the voltage) would be required. Connections for a three
sheet system would require a J3. A J4 Harness will connect four sheets of
Heating Film together. If there are three and a half sheets needed, a J4 can
be used by trimming off the unused portion of the Harness.

2. Adders (A, A2, A3, A4): Adders are
used to attach one sheet of Heating Film
to another, when a thermostat cold lead
connection is not required. Adders are
available in 120 volt and 240 volt
configurations. To add a single sheet
of Heating Film to a 120 volt system, an
“A-120” (A indicates one additional
sheet, 120 indicates the voltage) would
be required. To add two sheets to an
existing sheet, use an A2. To add three sheets, an A3 will be required.
An A4 will connect up to four sheets to an existing sheet or sheet set.
3. Jumper (JP-60): A Jumper can be
used to reconnect a copper bus bar if it
has been cut for completion of the
layout. The Jumper is sixty (60”) inches
in length and can be used on both 120
volt and 240 volt systems. They are
helpful for going through door ways,
around corners, around posts, and
around columns. Jumpers can also be
used around cut outs for floor ports
such as receptacles, registers, and floor ports.

SECTION 1
EDGE SEALING TAPE
It is critical to seal any cut that is made to the gray
area of the Heating Film. The Edge Sealing Tape
comes in one length (42 inches), but in two
different widths, 4.8 inches wide and 2.4 inches
wide. The wider Edge Sealing Tape (4.8 inches
wide) is used to seal the edge of the Heating Film
to which the wiring Harness, or Adder is attached.
The narrower Edge Sealing Tape (2.4 inches wide)
is used to seal any cut edges where there is no
attached wiring Harness, Adder, or any other cuts (including holes cut in
between the copper bus bars) that have been made to the Heating Film during
the installation process. The Edge Sealing Tape is a highly-adhesive
fleece-backed butyl tape. The fleece backing that is the same as that used on
EverWarm Radiant Heat Film, making the Edge Sealing Tape compatible with
all types of adhesives.
REMEMBER: THE EDGE SEALING TAPE MUST BE USED ON ANY GRAY EDGE,
OR GRAY AREA OF THE HEATING FILM THAT HAS BEEN CUT.
THERMOSTATS
EverWarm Radiant Heat offers a variety of direct line voltage thermostats in
both programmable and non-programmable models. All EverWarm Radiant
Heat thermostats in the United States are GFCI-protected (required by the
NEC). Each thermostat includes a floor sensor, which EverWarm Radiant
Heat requires for each installation. Each thermostat senses both ambient air
and floor temperatures, enabling installers to set the floor temperature to the
flooring manufacturer’s desired set point, along with maximizing the potential
comfort of the room’s environment. The maximum load allowed on a standard
thermostat is 15 amps. The maximum amount of total Heating Film allowable
per circuit translates to the following:
110-120VAC: 31.25 LINEAR FT = 100 FT2PER ZONE (1 THERMOSTAT)
220-240VAC: 62.5 LINEAR FT = 200 FT2PER ZONE (1 THERMOSTAT)
Installations that require a larger amount of Heating Film per thermostat (over
200 square feet per zone) will require the use of a “master” thermostat that
controls a “slave” power unit. Up to 2000 square feet of Heating Film can be
installed and combined using 10 slave units. Up to 10 Slave Units can be
controlled by one Master Thermostat.

SECTION 3
INSTALLATION GUIDELINES:
THE FOLLOWING SECTION OUTLINES THE PREPARATION
REQUIRED PRIOR TO INSTALLING THE HEATING FILM.
FLOOR PREPARATION
1. Ensure slab or wood sub-floor is structurally sound (follow TCNA
installation guidelines for sub-floor rigidity).
2. Concrete slab must be free of waxy or oily films and curing compounds
(when present, mechanical scarifying is necessary). If these chemicals
are present, water will bead. If the sealer is left on the floor, the mortar
for the tiles won’t adhere. Remove sealer with a floor sander using
medium-grit sandpaper.
3. There should not be any protrusions sticking up from the sub-floor that
could impact or cause damage to the Heating Film such as nails, rebar,
or any other potentially damaging material.
4. Level the floor per TCNA guidelines. Allow the compound to dry
following manufacturer’s recommendations.
5. Mop or sponge the floor with clean water to remove any traces of dust.
6. Make sure the floor is completely dry before installing EverWarm
Radiant Heat Film.

(See notes).
NOTE: EverWarm PRODUCTS, LLC DOES NOT RECOMMEND THE USE OF
MODIFIED THIN-SET MORTARS TO SET TILE OVER THE HEATING FILM BECAUSE
THESE MORTARS MUST AIR-DRY TO CURE PROPERLY. WHEN “SANDWICHED”
BETWEEN TWO IMPERVIOUS LAYERS SUCH AS EverWarm AND PORCELAIN TILE,
DRYING TAKES PLACE VERY SLOWLY THROUGH THE OPEN GROUT JOINTS.
*Exception: Certain moisture-sensitive stones, (e.g., green marble or resin-
backed tiles) may require special setting materials. Please consult the stone
supplier for more information. For an acid-resistant covering, use an epoxy
adhesive to set and grout the tile.
