Materials
and Tools Required:
• WarmlyYours TempZone™ Heating Rolls
• Thermostat with Sensor Probe Wire
• 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
• Latex-Portland Cement (acrylic or latex modified thin-set mortar)
• Plastic Notched Trowel
• Flat Rubber Trowel (float 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.
Preparation:
1. Cross-check the items 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 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.
Concrete Subfloor Applications:
Prepare the subfloor as per flooring manufacturer recommendations. In some cases,
leveling of the subfloor may be necessary. Leveling should be done before installing
heating rolls. Insulating over concrete slab: Adhere the ¼” cork or 3/16” CeraZorb®
insulating underlayment to the concrete with latex-portland cement using a 1/8”
v-notched trowel.
NOTE: Self-leveling cement cannot be poured directly over cork insulating
underlayment.
For applications where self-leveling cement must go directly over the concrete
insulator, we recommend using CeraZorb® insulating underlayment.
