Electrical Rough-In

5.1 Heating Cable Handling
WARNING: The electrical rough-in must be done by
qualified personnel familiar with generally accepted
construction techniques and safe electrical practices.
The installation must comply with all national and local
electrical codes. If you are unfamiliar with these require-
ments, contact a licensed electrician.
Step 1: Confirm power supply is appropriate
Confirm that the power supply is either 120 V, 208 V or
240 V depending on the mat you chose. The floor heating
system must be connected to an appropriate sized
electrical circuit. Refer to the Product Selection Table
on pages 8–9 for individual mat current levels.
Ground-fault protection is provided by the QuickStat ther-
mostat if the system is using a 120 V power supply. If the
QuickNet system is powered by a 208 V or 240 V supply,
a separate Ground-Fault Circuit Interrupter (GFCI) must be
used.
Step 2: Install electrical junction box
Install the electrical junction box for the thermostat at a
convenient height—typically 5 feet above the floor and
within reach of the cold lead and the floor temperature
sensor.
Step 3: Install ground-fault circuit interrupter (GFCI)
breaker at electrical panel (for 208 V or 240 V
installations)
Install a separate Class A GFCI (5mA trip level) breaker at
the electrical panel when installing the QuickNet system
using 208 V or 240 V power supply.

Installation

6.1 Install the QuickNet System
Tools and materials required
You will require the following items to install and test the
floor heating system:
• Scissors
• Utility knife
• Wire strippers
• Tape measure
• Screwdriver
• Multimeter
You will also need the appropriate tools and materials to
install your particular floor. These will likely include prod-
ucts like self-leveling mortar, thin-set mortar, backer board,
tile, a notched trowel, and any other tools for your specific
floor.
Follow these steps to ensure a successful QuickNet
installation.
Important: Do not cut the heating cable.
Important: To prevent damage to the QuickNet
system, do not overlap the heating cables.
Step 1: Prepare the subfloor
Make sure the floor area to be heated is clean, flat, and
free of debris that can damage the mat, such as nails,
staples or protruding objects.
When installing the QuickNet floor heating system over a
concrete subfloor, it is strongly recommended that a layer
of insulation be put down above the subfloor and under-
neath the QuickNet heating mat. The insulating layer will
help to transfer a greater amount of the heat generated to
the floor surface.
Drill or cut a hole through the wall sill plate under the elec-
trical junction box location. You will use this hole to route
the cold lead and the floor temperature sensor wire to the
electrical junction box.
