Step 6. Install Thermostat Sensor
A floor sensor comes with the recommended thermo-
stat control. The sensor wire can be installed without
a conduit or in a conduit separate from the electrical
power leads if conduit is required by code. Open a
second knockout in the bottom of the thermostat box.
Feed the sensor (and conduit, if including) through the
knock-out, down the wall cavity, through the opening
in the bottom plate. Temporarily tape the sensor to the
slab or subfloor in a location approximately 6” to 12”
from the wall---final location of sensor after mat in-
Step 1. Inspect and Test Heating Mats
Verification that the heating mats were received in operable condition is important prior to installation. When the
heating mats are removed from the shipping box, test the resistance using ohm meter and record the information.
If the resistance reading varies more than ±3% from the recorded readings on each mat, do not install the mat
and contact your supplier for assistance.
Step 2. Preparing the Stable Sub-floor
Clear the floor of all debris, nails, etc. so the floor is smooth, clean and dry.
stallation will be taped down at the edge of or in
between two mats so that the sensor is not directly
above a heating mat. (NOTE: The sensor is located in
the thermostat packaging.
Step 7. Rough in the Wiring
Install appropriate electrical wire (conductor) from
the power source and breaker protection to the ther-
mostat following all codes. Leave 6” to 8” extra wire
at the thermostat box.
NOTES:
It is EXTREMELY important to verify the resistance measurements for each mat and to record the readings on the
system checklist (see page 16). If a defective mat is adhered to the floor it can be very difficult to remove it.
The heating product shall not extend beyond the room or area in which it originates.
The heating product is not to be installed in walls.
It is very important that the mats be installed ONLY after the sub-floor is complete and stable.
Adhering the mats to an unstable floor can result in damage to the mats and will void the
manufacturer’s warranty.
