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

• 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.
