. Electrical Rough - In: New Construction
For new construction it is recommended that rough-in be completed before dry-
walling begins.
• 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.
• Install the ECB, adjusting box projection to suit expected wall covering (Figure 3a).
• Prepare a fish hole, first by drilling a horizontal !" diameter hole through the sill plate approximately
1"" deep.
• Drill a second !" diameter hole vertically through the sill plate connecting to the first hole (Fig-
ure 3c). If installation will require two mats, a second fish hole should be drilled a minimum
of 4" from the first but within the same wall cavity.
• Clear fish holes of wood chips and install included cable guards (from the thermostat kit) over
holes (drywall ledge at top, facing out) over the holes (Figure 3b).
• Install a fish cord through the sill plate, pull through the wall cavity, and secure in the ECB. ONE
ADDITIONAL FISH CORD WILL BE REQUIRED IF THE INSTALLATION WILL INCLUDE A
FLOOR TEMPERATURE SENSOR.
• Fasten “Do Not Remove” tags (from the thermostat kit) to fish cords at the sill plate holes (Fig-
ure 3d).
• Install Power Supply Wiring, but do NOT energize or connect to the heating controller until
the finished flooring has been installed. Install conduit if required (consult with your local
inspection authority).
• 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.
