In Part 1 of this series, you cut the drywall and began to run cables for your electric wall heater. Follow the simple steps below to complete installation.
Step 1: Making the Wire Connections
Once the cable is inserted and secured in the heater’s inner junction box, you must make the wire connections. These will greatly depend on the heater’s manufacturer’s instructions and the voltage.
Use a wire cutter to strip a few inches of sheathing from the cable. Push it through the clamp and into the heater can. While doing this check that at least part of the sheathed wire is inside the inner box.
Step 2: Connect to the Heater
Your next step is to connect those wires to the heater’s wiring. You will notice 2 wires: black and white. Both are hot feeds, so to better identify this, tape black electrical tape around the white wiring. Use wire connectors to onnect these wires to the black heater wires.
Thrust the can and cable into the stud space. It is always recommended that you run a separate circuit to the main electrical panel as this is a much safer route and it will also help to avoid any overloading. If you have never done this type of electrical work before it is always best to hire a professional electrician as it can be a dangerous task since after all electricity and currents are involved.
Step 3: Install the Heater Unit
Once done, fasten the can to the framing by securing with screws, making sure it is tightened well. Finally, install the cover grill.
Step 4: Connect to the Thermostat
Stretch the last part of the cable until you reach the thermostat unit. You will have to cut a small area for the switch box to fit in the wall. Push the cables into it, and then fit it in this area in the wall. Tighten with screws.
Step 5: Connect to the Main Panel
Cut slightly above the service panel where you will pass the wires through until you reach the service panel where the wires will be hooked up. Pull the wires so that there will be enough length to do the connection without problems. At this point, it is best to hire an electrician to do the final wiring as it could be disastrous for you to hit a live wire.
Step 6: Cover the Area
Most people prefer to cover this area so that it looks neater and so that can will easily access it in case of necessary maintenance. It is enough to cut a piece of plywood and fit it in the wall area.
