Installation Instructions

1.1
ELECTRICAL ROUGH-IN : NEW CONSTRUCTION
z Determine the appropriate location and height for the Electrical Connection Box* (ECB). Consider proximity to other outlet boxes, ease of
routing Cold Lead to the Heated Area, and accessibility of the heating controller during normal use. Typically the cold lead enters the same
wall cavity in which the ECB is located.
z Install the ECB, adjusting box projection to suit expected wall covering (Figure 1a).
For new construction it is recommended that rough‑in be completed before drywalling begins.

z Prepareashhole,rstbydrillingahorizontal¾"diameterholethroughthesillplateapproximately1½"deep.
z Drillasecond¾"diameterholeverticallythroughthesillplateconnectingtothersthole(Figure 1b). If installation will require two
cables,asecondshholeshouldbedrilledaminimumof4"fromtherstbutwithinthesamewallcavity.

z Installashcordthroughthesillplate,pullthroughthewallcavity,andsecureintheECB.ONEADDITIONALFISHCORDWILLBE
REQUIRED SINCE THE INSTALLATION MUST INCLUDE A FLOOR TEMPERATURE SENSOR.
z Fasten“DoNotRemove”tagstoshcordsatthesillplateholes(Figure 1d).
z Install Power Supply Wiring,butdoNOTenergizeorconnecttotheheatingcontrolleruntilthenishedooringhasbeeninstalled.
Install conduit (Figure 1e) if required (consult with your local inspection authority).
z Drywall installation can now be completed and heating cable can be installed later.
* Typically requires a 15 cubic inch box for single cable installations. Multiple cable sets may require larger boxes. Consult your local electrical authority.
