Do’s
DO carefully read this installation manual before commencing installation.
DO maintain a gap of min. 2”, max. 4” between the heating cable runs at all times.
DO make sure all electrical work is done by qualified persons in accordance with local
building and electrical codes, the National Electrical Code (NEC), especially article 424,
Part V of the NEC, ANSI/NFPA 70, for the US and Canadian Electrical Code, Part 1,
for Canada.
DO check the resistance of the heating before, during, and after installation to ensure that
the heating cable has not been damaged. The value should match the rating label
found on the product. A tolerance of +/-5% is allowed.
DO ensure that the heating mat is connected to a Class A Ground Fault Circuit Interrupter
(GFCI) when used in bathrooms. Check your local code requirements for installations
outside of bathrooms. It is not common to require a GFCI protection outside of
bathrooms.
DO plan the heating system layout and installation so that any drilling after tiling (e.g. for
fixtures such as vanity units, tubs) will not damage the wiring. Remember to keep a
copy for future reference.
DO take some pictures of the mat installation before installing the floor covering for
future reference.
DO ensure that the minimum bending radius is no less than 1”(25mm) for the
heating cable.
DO allow sufficient drying/curing of the subfloor before commencing installation of the
heating mat.
DO ensure that each tile is solidly bedded in tile adhesive, with no gaps or voids beneath.
DO make sure that ALL heating cable including the joints are positioned under the tiles
and completely embedded in adhesive.
DO remember to install the floor probe for the Warmup® thermostat. The floor sensor
should be located in the centre of two heating element runs. Ensure that the sensor
does not touch or cross over any of the heating cables.
DO ensure that the cold tail conduit is kept separate from the sensor conduit.
DO remember to attach the rating labels included within this manual to the circuit breaker
and thermostatic controls.
