10 Warmup StickyMat Installation Tips:

1. Take photos of the mat installation before covering over for future remodeling reference.
2. Check the resistance of the heating before, during, and after installation to ensure that the heating cable as not been damaged. The value should match the rating label found on the product label and a tolerance of +/-5% is allowed.
3. Do not use staples or other metal fixings.
4. Do not cut the blue heat cable.
5. The floor sensor will most likely sits too high, requiring you to cut a channel in the floor to recess the floor sensor and ensure that it sits at the same height as the heating cables.
6. Dry fit your mat, and use a permanent marker to locate it on the floor. Also mark the cold leads and sensor locations.
7. Roll out the mat following your floor plan. Cut and turn as needed.
8. Place the mat with the element facing the sub-floor.
9. Avoid damaging the heating cable with trowels and other tools.
10. Secure the mat to the sub-floor using the double-sided tape on the mat, press firmly and flatten out the mat..
11. Use tape to fix any loose laid wires and the power leads in place.

Removing the adhesive tape covering

NOTE: Do not cross cables at any time. Avoid contacting the power lead or sensor with the heating element cables.

Each Warmup heat mat has one unheated lead running from the floor to the thermostat’s electric connection. The joint connecting the unheated lead to the heating coils must be at least 2 inches away from the wall and covered by a thinset adhesive under the final floor covering.

Safety Tip: This unheated lead joint SHALL NOT be installed in the wall. In order to get the joint flush with the heating mat, it will be necessary to chisel out a recess in the sub-floor. I found that recessing this joint slightly into WIB underlayment allowed me to get the mat to lay flat in this area.

Multiple StickyMats Connection Tip:

It is easier to run multiple lead wires to a junction box and then take a single wire to the thermostat. Ensure that the thermostat connected to a Ground Fault Circuit Interrupter (GFCI), is added to the circuit between the main power supply and the thermostat.
