ELECTRICAL ROUGH-IN : REMODELING PROJECT
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 to a planned heating controller. The cold lead should enter the same wall
cavity in which the ECB is located. Contact your local electrical inspection authority for electrical code requirements.
z Removebasemoldings,anddrywallonlyasrequired,inareaswhereshholesaretobedrilled,exposingupperedgeofsillplate.
z Drillahorizontal¾"diameterholethroughthesillplateapproximately1½"deep.Ifinstallationisplannedfortwoheatingcables,a
secondshholeshouldbedrilledaminimumof4"fromtherst,butwithinthesamecavity(Figure 1f).
z Useachiseltocompletelynotchwoodfromthesillplateaboveeachhole.Clearshholesofwoodchipsandinstallcableguards
(drywall ledge at top, facing out) over the holes (Figure 1g).
z Use ECB as template to mark outline on wall. Carefully cut out the minimum possible amount of drywall to prevent the need for wall
repair after heating controller has been installed (Figure 1h).
For a remodeling project, complete the electrical rough‑in as follows:
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 (Figure 1i).
z Install Power Supply Wiring in the ECB, but do NOT energize or connect to the heating controller. Install conduit, if required
(consult with your local electrical inspection authority).
* Typically requires a 15 cubic inch box for single cable installations. Multiple cable sets may require larger boxes. Consult your local electrical authority.
