STEP 7: TEST ThE SYSTEM RESiSTAnCE
Test and record element resistance of each
mat. Check for shorts between the ground
and each of the other wires before proceeding.
(See documentation procedures outlined on
page 5.) LATICRETE Floor HEAT mat(s) can be
monitored throughout the installation process
with the use of LATICRETE Wire Eye electric wire fault indicator.
STEP 8: MARK ThE lEAD PAThS
While the mat is laid dry in place, mark the
desired sensor location, the sensor lead path
and the supply lead path back to the control
location on the underlayment and on the
installation layout.
STEP 9: PREPARE gROOVE(S) FOR lEAD(S)
In the case local codes require sensor lead
paths and supply lead paths to be placed
in grooves notched into the subfloor or
underlayment, remove mat from work space
to avoid the risk of damaging the mat. Do
not leave the mat in the area where the
groove(s) need to be notched. Completely remove the mat from the
working area marked for the sensor, the sensor lead path and the
supply lead path. Prepare a groove in the subfloor or the underlayment
for the Supply Lead Wire(s) or Supply Lead Conduit (per your local codes).
Clean groove thoroughly.
STEP 10: SECuRE ThE MAT
LATICRETE Floor HEAT is provided with
self-adhesive backing and tape
ease of installation. After the area is
cleaned and prepared, simply place
LATICRETE Floor HEAT mat(s) in place and
apply pressure to adhere to subfloor or
underlayment. For increased stability staple the mesh in between the
heating element wires. Never staple over element wires.
STEP 11: SECuRE ThE SuPPlY lEADS
Secure the supply leads in the groove(s) with
hot glue if desired.
STEP 12: inSTAll ThE lATiCRETE FlOOR WARMing
ThERMOSTAT FlOOR SEnSOR.
A hot glue gun can be used to hold sensor in
place if preferred. Installing the sensor in a
groove may be required by local codes. Run
the LATICRETE sensor down the wall in a 1/2"
(12 mm) conduit and weave it into the mesh of
the LATICRETE Floor HEAT mat so that it runs in
between and/or parallel to the heating wires from an open side of the mat.
STEP 13: TEST ThE SYSTEM RESiSTAnCE
Test and record element resistance of each
mat. Check for shorts between the ground
and each of the other wires before proceeding.
(See documentation procedures outlined on
page 5.)
STEP 14: TEST ThE SEnSOR RESiSTAnCE
Test and record control sensor resistance
using an Ohm Meter setting of 20K.
The sensor reading should register between
8K – 12K.
STEP 15: SET MAT in MORTAR
Option A: Use the flat side of a trowel OR
a rubber float to apply a smooth skim-coat
of thin-set mortar over LATICRETE Floor HEAT
mat. Make sure to use enough mortar to
encapsulate the heating element wire in its
entirety. Then allow the protective layer of
LATICRETE polymer fortified thin-set mortar
to set.
for
iMPORTAnT: The mat should be embedded
in 1/2" (12 mm) of thin-set mortar.
Option B: Apply a thin coat of LATICRETE 86 LatiLevel
underlayment (per LATICRETE 86 LatiLevel instructions) to completely
encapsulate LATICRETE Floor HEAT mat. Allow to cure per the product
instructions. See Data Sheet 0024.0 – LATICRETE Self Leveling
Underlayment Installation Instructions for more information.
iMPORTAnT: The mat should be embedded in 1/2" (12 mm) of self-
leveling underlayment.
