If you’re planning to install a wall furnace in your home, knowing how to properly wire it is crucial for safety and efficiency. The wiring process may seem complicated, but with the right tools and knowledge, you can do it yourself. In this article, we’ll guide you on how to wire a wall furnace step-by-step.
Before you start
Before you begin the wiring process, make sure you have the following tools: wire strippers, a screwdriver set, screws, wire nuts, and a voltage tester. Also, ensure that you have turned off the power supply to the furnace to avoid electrocution.
Step 1: Mount the furnace
The first step is to mount the furnace on the wall using screws. Make sure the furnace is level and that there is enough clearance around it for proper airflow. Refer to the manufacturer’s instructions for specific mounting details.
Step 2: Install the junction box
Next, install the junction box near the furnace. This junction box should be rated for the voltage and current of the furnace to ensure safety. Connect the wires from the furnace to the junction box using wire nuts.
Step 3: Connect the power supply
After installing the junction box, connect the power supply to the furnace. The power supply wires should be connected to the junction box using wire nuts. Use a voltage tester to ensure that the power supply is turned off before making any connections.
Step 4: Connect the thermostat
Now it’s time to connect the thermostat. The thermostat will control the furnace’s temperature and turn it on and off accordingly. Connect the thermostat wires to the furnace control board based on the thermostat’s wiring diagram. Again, use wire nuts to make the connections.
Step 5: Test the connections
After making all the necessary connections, test the furnace to ensure it’s working correctly. Turn on the power supply and adjust the thermostat to the desired temperature. If everything is connected correctly, the furnace should turn on and start heating.
