Decide where the heater will be installed. Find the power source in the fuse box for the location where the heater will be installed, and turn it off.
Drill a hole in the wall, using a half-inch drill bit, at the location where the electrical supply for the heater will be. Because you're installing a baseboard heater, the hole will be near the floor. The heater installation will require at least 10 inches of supply wiring.
Mark the wall at each end and the top of the heater with a pencil to note where the heater will go. Using a pencil, mark two wall studs above the heater. The studs should be close to the ends of the heater, as the unit will be attached to them. Move the heater away from the wall.
Lay the heater face-down on the floor. Using a flat-head screwdriver, remove the screws on the back of the heater to gain access to the wiring compartment.
Loosen the screw on the cable clamp at the bottom of the heater, using a flat-head screwdriver. Don't remove the screw. Insert the grounding cable into the slotted area of the wiring compartment. Pull 6 inches of grounding cable through the slotted area.
Replace the wiring compartment cover by securing the four screws with a flat-head screwdriver. Stand the heater upright, and place it against the wall at the desired location.
Remove the heater’s cover to expose the heating element. At the same time, find the places near each end of the heater where the wall studs are located. Attach the heater to the wall at these points, using wood screws. Units that are longer may require an additional screw in the center. Tighten the screws and then loosen them a quarter turn to allow the heater to expand and contract during use. Replace the cover.
Remove the screw on the bottom front panel of the wiring compartment, using a flat-head screwdriver. Connect the grounding cable to the copper pigtail wire under the loosened cable clamp. Screw in the cable clamp connecting the wires, using a flat-head screwdriver, until the wires are secured under the cable clamp. Replace the front panel of the wiring compartment, using a flat-head screwdriver. At this point you can restore the power.
