Time Installer Line at 1.800.778.9276 for valuable
installation tips.
HOW TO TEST NUHEAT MAT
Insulation Test
To ensure Nuheat Mat conductors are fully insulated:
1. Acquire digital ohm/multimeter with
alligator clips or equivalent device.
Set the ohm/multimeter to measure
resistance (ohms).
2. Place one probe clip on the metallic
braid (ground wire) and the other
probe clip on the conductor inside
the white lead.
3. Confirm that the reading is OL or infinity (open circuit).
Resistance Test
To ensure continuity in each Nuheat Mat:
1. Acquire a digital ohm/multimeter
with alligator clips or equivalent
testing device. Set ohmmeter to
appropriate setting. Place one clip
probe on conductor in the white
lead and other probe clip on the
conductor in the black lead.
2. Confirm your ohm reading is within
+10% / -5% of the factory reading
listed on the mat tag. Record the ohm reading in the Mat
Resistance Log (page 4).
Nuheat Mat must be tested before, during and
after the installation to validate the warranty.
ELECTRICAL INSTALLATION
All wiring must follow specifications set out in Part 1 of Canadian
Electrical Code, or Article 424 of the National Electrical Code ANSI/
NFPA 70, or whichever is applicable to local electrical inspection
regulations and authorities. All Nuheat mats must be connected
to the electrical service through a Class “A” Ground Fault Circuit
Interrupter (GFCI). A GFCI is built into all Nuheat controls. The
supply leads of Nuheat Mat may need to be routed inside suitable
conduit according to local electrical codes. Check with the local
authority having jurisdiction to determine requirements.
1. Connect braided ground wire to
electrical box grounded copper
conductor using approved wire
connectors.
2. Attach corresponding lead wires to
junction box using CSA Certified /UL
Listed cable fittings. Make electrical
connection only after flooring is

supply conductors. Supply conductors shall be suitable for
residential wiring according to local and national electrical code.
In all cases, do not exceed box fill for conductors. Typically, only
3 Nuheat mats may be connected to a supply conductor in a
standard device box.
WARNING: Risk of electric shock and fire. Damage to
supply conductor insulation may occur if conductors
are routed less than 2’” (51mm) from heating wire.
Refer to installation instructions for recommended
means of routing supply conductors.
3. Affix supplied orange label to panel board beside appropriate
circuit indicating branch circuit supplying power to Nuheat Mat.

Should you have any questions or difficulties installing or controlling
your Nuheat Mat, please contact Nuheat directly at 1.800.778.9276.

NUHEAT INDUSTRIES LIMITED
PART 1: SECURE NUHEAT MAT TO SUBFLOOR
WARNING! RISK OF ELECTRIC SHOCK AND FIRE.
DAMAGE TO SUPPLY LEAD INSULATION MAY
OCCUR IF LEADS ARE NOT ROUTED ACCORDING
TO NUHEAT MAT INSTRUCTIONS BELOW.
1. Ensure subfloor is clean and free of debris. Mark location of supply
leads on subfloor. Lay out path of leads to junction box around
the perimeter of Nuheat Mat. If leads do not reach designated
junction box, connect the leads to an accessible junction box.
Run power to this junction box from the designated junction box
using suitable electrical wiring. Where possible, connecting leads
should be laid in low traffic areas.
FOR INSTALLATIONS REQUIRING COLD LEAD
TRIM OR SPLICE, ELECTRICAL RATINGS LABEL
SHALL BE FIXED TO THE COLD LEAD AND
VISIBLE AT TERMINAL JUNCTION BOX.
Conduct insulation & resistance tests and record
reading in the Mat Resistance Log (page 4).
2. Dry fit Nuheat Mat to ensure it fits
room contours and provides proper
coverage. If Nuheat Mat does not fit,
contact your place of purchase. The
mat should be installed a minimum
of 2” away from walls.
3. Prepare acrylic / latex modified thinset
to adhere Nuheat Mat to subfloor.
Dampen any folds in mat with water to assist adhesion.
4. Using at least ¼” x ¼” square notch trowel, spread a minimum
0.25” coat of fresh acrylic / latex modified thinset over the area to
be covered by Nuheat Mat. Make your thinset grooves parallel
to the mat wires. If laying Nuheat Mat in a large area, make sure
to work on one manageable section at a time.
5. Place Nuheat Mat onto the fresh
thinset pressing firmly with grout
float or lightweight roller. Create
100% contact between heating mat,
the thinset and the subfloor. Press
out any air bubbles or wrinkles and
ensure that the surface is flat.
6. Route supply leads to junction box
according to path laid out in Step 1. Ensure leads are flat;
temporarily tape down as necessary.
Conduct insulation & resistance tests and record
reading in the Mat Resistance Log (page 4).

reading in the Mat Resistance Log (page 4).
4. Install vapor barrier, if applicable, and underlay as per
manufacturer’s instructions and guidelines.
5. If installing a Nuheat floor-sensing
thermostat with GFCI, ensure that
the floor-sensing probe is installed at
this point. Ensure the tip of the probe
is approximately 12” in from the edge
of Nuheat Mat. Secure the probe on
top of the thinset using duct/electrical
tape. Please see floor-sensing
thermostat instructions for proper
connection procedures.
Sensor probe MUST be placed above the underlay
to avoid compromising performance of Nuheat Mat.
6. Install laminate/engineered wood floor as per manufacturer’s
instructions and guidelines.
After installation, gradually increase Nuheat Mat
temperature to maximum setting (82°F or 28°C)
over a 72 hour period or according to flooring
manufacturer’s guidelines.

probe is placed between two heater
wires. Ensure the tip of the probe is
approximately 12” in from the edge
of Nuheat Mat. Secure the probe on
top of the Nuheat Mat using duct/
electrical tape. Please see floor-sensing thermostat instructions
for proper connection procedures.
3. Apply a minimum 0.25” coat of thinset on top of Nuheat Mat
according to tile or stone manufacturer’s recommended
thickness. Install tile or stone on top. Tile must be installed
according to requirements of ANSI A108.5.
4. Clean excess thinset from grout lines with a sponge or small
brush and water as tile is being laid. The use of sharp objects
or power tools to clean grout lines may damage Nuheat Mat
and will void the warranty.
Conduct insulation & resistance tests and record
reading in the Mat Resistance Log (page 4).
5. After thinset has cured, apply grout.
Before activating Nuheat Mat, allow 72 hours
to 1 week for thinset or adhesive to cure, or
