WarmlyYours TempZone FLEX (Twin) Conductor 120V or 240V - Manual (Page 11)

Materials
and Tools Required:
• WarmlyYours TempZone Heating Rolls
• Thermostat with Sensor Probe Wire (if applicable)
• Custom Design Layout (provided free with quote)
• Digital Ohm Meter (required for completion of warranty registration card)
• Circuit Check (sold separately)
• Scissors
• Staple Gun or Hot Glue Gun (concrete applications)
• Duct Tape or Box Tape (we recommend 3M 6969 Hi-Temp Duct Tape)
• Latex-Portland Cement (acrylic or latex modified thin-set mortar)
• Plastic Notched Trowel
• Self-leveling Cement
• ¼” Cork or 3/16” CeraZorb® concrete insulating underlayment (WarmlyYours offers
both of these products), or similar, is recommended when installing over concrete. This
is recommended to increase efficiency, but is not mandatory.
See Thermal Insulating & Sound Control Underlayment installation instructions.
We do not recommend using self-leveling cement directly over cork insulating
underlayment. However, self-leveling cement can be used directly over CeraZorb®
insulating underlayment.
When Installing in Wet Locations
•. Installation shall be in accordance with the National Electric Code, NFPA-70 and CAN/
CSA- C22.1, Canadian Electric code, Part 1 (CEC) and that final acceptance is to be
made in the field by the Authority Having Jurisdiction (AHJ).
• WarmlyYours recommends using a separate Mat for shower areas.
Note: The UL Listing for this product covers use in wet locations for CANADA only. Wet
location installation in United States shall be in accordance with the National Electric
Code, NFPA 70 and any other applicable jurisdictional code and final acceptance is to
be made by the Authority Having Jurisdiction (AHJ).
• If insulation board is being used over a slab, use suitable glue or cement based
adhesive or thinset mortar to adhere it to the slab. If installing in a wet location,
ensure the slope of the mortar bed is maintained to direct water to the drain pipe.
Note: For wet location installaions, WarmlyYours recommends installing a secondary
waterproofing membrane over the mortar bed covering the wire, as per membrane
manufacturer’s instructions. This will protect the mortar bed from any moisture that
may seep through the tile, which could cause mold problems over time.
Preparation:
1. Cross check the items you received against the packing list and the materials list on
the installation plan to ensure that the roll length and thermostat type are an exact
match.
2. Perform 1st ohm test - Measure the resistance of each mat with an Ohm meter
(reading core wire to core wire) and record the readings on the UL label and on the
installation plan. The Ohms readings should be within a +/- 15% variance of the Ohm
value specified on the UL tag. Measure the continuity between each core wire and
ground wire – The reading should be O/L or infinity.
3. Prepare the subfloor to be clean and free of debris.
4. Do a dry fit of the rolls on the subfloor according to the custom design/installation
plan. Measure and mark the mats and subfloor if necessary.
5. Make any adjustment in the layout PRIOR to cutting the roll.
6. When using Self-Leveling Underlayment (SLU), we suggest priming the floor
before laying out the rolls. Doing so will ensure that the primer covers the subfloor
completely. Whenever using SLU, ALWAYS follow the installation recommendations
set forth by the SLU’s manaufacturer. It is very important to adhere the heating roll
securely to the subfloor, otherwise the heating wire may float to the top of the SLU.
Please call WarmlyYours at (800) 875-5285 if the roll does not provide the specified
coverage or for 24/7 installation and technical support.
