Instructions / Assembly

12
For each Warmup heating mat you install, you will have 1 unheated lead running from the
floor to the thermostat’s electric connection. The joint connecting the unheated lead to the
heating mat must be at least 2 inches from the wall and placed in a position to be covered by
a thinset / adhesive under the final floor covering. THIS JOINT SECTION MUST NEVER BE PLACED
IN THE DRYWALL.
It may be necessary to chisel out short channels in the subfloor to minimize the increased
height presented by the floor probe and the unheated lead.
Neither the unheated lead or sensor wire must cross, or come into contact with the heating
element. Bear in mind that you will need to make provisions for drawing the unheated lead
and sensor wire up through the conduit to the control box.
NOTE: The leads must be protected where they leave the floor, by rigid metal conduit,
intermediate metal conduit, rigid non metallic conduit, electrical metallic tubing or by other
approved means.
The installation of electrical systems presents risks of fire and electrical shock which can result
in personal injury. Caution should always be taken to guard against each such risk.
All electrical connections should be carried out by a qualified electrician in accordance with the
National Electrical Code and all local Codes. For installations in Canada, refer to sections 12 and
62 of the CEC.
The Warmup heating mats MUST be connected to the electrical system through a Ground Fault
Circuit Interrupter (“GFCI”). If you are not using a thermostat with a built-in GFCI, ensure that
the branch circuits that supply your panels are GFCI-protected, or, if possible, a dedicated GFCI
is incorporated in each circuit supplying your panels. This requirement is critical to the safe
operation of your Warmup heating mat.
