• CONDUCT RESISTANCE AND INSULATION TESTS ON THE MAT(S) "BEFORE", "DURING" AND "AFTER" THE INSTALLATION PROCESS IN ORDER TO MAINTAIN WARRANTY. (See Section D)
• All first time tile installers and electricians are required to contact the manufacturer prior to installation. At this time, a technical representative will briefly clarify critical installation procedures. Failure to follow this instruction will void the product warranty.
• Please read the installation instructions completely and use the mats with caution appropriate for an "electrical" and "heating" product.
• Choose which controlling device(s) are required before installation; especially if installing the floor-warming control with G.F.C.I.
• Product warranty applies under ceramic tile, marble and natural stone installations only.
• Allow at least 72 hours to 1 week for the mortar to cure, or according to manufacturer specifications, before activating your mat.
• It is mandatory to install a Class "A" G.F.C.I. or G.F.C.I. circuit breaker with each installation. Mats must be installed on a dedicated circuit.

• Measure the area(s) to be heated to determine which mats will fit your application.
• Allow for obstructions (vanities, vents, exposed plumbing, etc.).
• Remember that mats have no ‘up’ or ‘down’ side -- mats may be placed side by side maintaining at least 1" clearance between the heating wires.
• There is little or no horizontal heat travel. Please consult Warm Floor for design and sizing assistance.

Conduct resistance & insulation tests on the mat(s) at least three times during the installation process. See Section D for more information.

Avoid the following activities that may damage mats:

• unnecessary folding
• walking on unit (protect with a cover like plywood)
• stapling
• nailing
• dropping heavy objects on mat(s)
• Do Not Use grout scrapers or exacto knives to clean grout joints. Cleaning grout joints with sharp tools may damage the mat. Using these tools will void the warranty.

Allow your mat(s) to "breathe" by avoiding "zero-clearance" furniture (i.e., solid oak cabinets, etc.).

Ensure that new occupants are aware that mat(s) are installed in the home.

Ensure that the subfloor is free of debris and suitable for the floor covering before installing the mat(s).

I) INSULATION TEST

To ensure that the copper conductors are fully insulated:

• acquire an ohmmeter or equivalent testing device
• place one meter probe on the ground (outer metallic braid) and the other probe on the copper wire inside the white lead
• confirm that the reading is 1 million ohms to infinity
• repeat these steps to check the reading between the metallic braid and the copper wire inside the black lead

To ensure continuity in your heating mat:

• acquire an ohmmeter or equivalent testing device
• set the ohmmeter to the lowest setting
• place one of the meter probes on the copper wire in the white lead and the other probe on the copper wire in the black lead
• check to see that your reading in ohms closely matches the reading listed on the tag of the mat being tested.

All wiring must follow specifications set out in Part 1 of the Canadian Electrical Code, the US National Electrical Code and local electrical inspection regulations. All mat units must be connected to the electrical service through a Class "A" Ground Fault Circuit Interrupter.

INSTALLATION STEPS:

1. Connect the braided ground wire to the electrical box ground screw and attach to the G.F.C.I. with a standard ground copper conductor.
1. Attach the connecting wires to the outlet box using CSA Certified/UL Listed tubing fittings. Tighten the diameter of the tubing fittings to 1/5" (5mm) to secure the connection.
1. Make the electrical connection only after the flooring is complete. Whenever possible, the connecting tubing should be laid in low traffic areas.

To ensure a successful installation, it is recommended that high quality, factory thinset mortars meeting the requirements of ANSI A118.4 be applied.

1. Mark the locations of the connecting tubing and connection patch on the subfloor. Lay out the path of the 10' lead to the wall box around the perimeter of the mat(s). (Conduct TEST #1)
1. Using at least a ¼" x ¼" square notch trowel, lay a coat of fresh mortar over the area to be covered by the mat(s).
1. Place mat onto the fresh mortar pressing firmly with grout float or lightweight roller. Create 100% contact between the heating unit, the mortar and the subfloor. Make sure that there are no air bubbles or curls and that the surface is flat to receive tile.
1. If leaving overnight, place a skim coat of mortar over the surface of the mat to cover it completely. Level the areas of the floor that are not covered by the mat(s). (Conduct TEST #2)
1. If installing a floor-warming control with G.F.C.I., ensure that the floor-sensing probe is installed at this point.
2. Set the tile on the mat. Tile must be installed according to requirements of ANSI A108.5. (Conduct TEST #3)
3. Clean the grout lines with a damp sponge/cloth as tile is being laid. The use of grout scrapers or exacto knives to clean grout joints will void the warranty.
