What Are the Steps to Install a Furnace?

The first step to installing a furnace is to ensure enough room for the stove. The central part of the furnace, the compressor, should fit in an area with at least 30 cm (12 inches) of clearance on all sides and above it.

The next step is to connect the gas supply line. This line must be run from outside into the furnace’s plenum box. Then, this gas supply line needs to be attached to another line, which runs along with one of two possible power lines. If your home uses 240-volt power, then you need both lines. Otherwise, you can use just one or neither of them – but not both! Attach these power lines to other wires running inside the furnace’s control compartment.

The next step is to connect the electrical supply line. This line needs to be run from your breaker box into the furnace’s control compartment. This also requires an electrical supply line that provides power for blower motors and lights on the stove and a low-voltage light or sensor that can tell if the doors on the plenum box are closed. These additional lines need to be attached to other wires running inside this same compartment.

After all of these connections have been made, you will need to install the blower motor and turn it on if it isn’t already installed. The next step is optional; some furnaces do not require any ductwork, while others may require more complex installations with several small ducts instead of just one large one. If you have a complex system, you should hire a professional to do the work for you, while simpler systems may be installed by anyone who can follow some basic instructions.

After this, your furnace is ready to be turned on so it can start cooling your home! Turn the power on at your breaker box and turn on the furnace’s electrical supply switch. Then open up the furnace’s access door, usually located in its control compartment, and set both of its temperature knobs to “max” or their highest setting. Then press down on each of these knobs with something like a broom handle; this will let electric current flow into the burners that heat the air in your system. These burners will light up automatically once the electricity reaches them, and this is what heats your home’s air.

Once these burners are lit, you can press the furnace’s on/off button to start its fan motor, which pushes cooled air into your home through its ducts. This button should also turn on its electronic control board, which regulates how hot or cold your home’s air gets. You may have to adjust the temperature knobs to feel too warm or cold inside.
