If you are just moving into your home or just beginning a renovation, you may want to install a new gas central heating system. Installing a gas central heating system can be complicated, but it is definitely a job that you can do yourself if you take the time to figure out what you are doing. Below are the steps you will need to take to complete this project. With a little patience and attention to detail, you will be well on your way to installing your new gas central heating system.

Step 1 - Map out Your Duct Work and Install

Before you begin installing the actual duct work, it is extremely important to plan out your duct configuration in order to make sure that there is enough room in the walls, floors, and ceilings to run your duct work and that there is enough space in each room of your house to connect the heating system. After you have mapped out the entire network of duct work, install the ducts piece by piece, ensuring that they reach every room where you want heat distributed.

Step 2 - Install Air Handler

The first thing that you will actually have to install will be the air handler, which will come in your central heating unit installation kit. This component is usually installed in the basement of your home, set off several feet from any concrete walls. When installing this component, make sure that the condenser drain is installed in such a way that it will be able to drain away safely.

Step 3 - Run Tubing Outside

Next, you will need to run tubing from the air handler itself to vent outside of your house somewhere above the foundation of your home.

Step 4 - Turn off Power

Turn off the main power to your home. Since you will be working with and around electrical wiring, it will be incredibly important from a safety standpoint to ensure that the electricity is turned off completely.

Step 5 - Install the Thermostat

Follow the directions on your thermostat to install it into a location on the wall of your home. Drill through the wall and attach the thermostat with screws and connect it to the main wiring of your home.

Step 6 - Attach Gas Line

You will next need to attach the gas line to your heating system. Unfortunately, you will not be able to complete this portion of the installation by yourself. Look in your phone book or online for a licensed gas installer to hook your gas line up to your heating unit. Once the gas line is hooked up, turn on your new gas heating unit and light the pilot light.

Step 7 - Turn on Power

Once you have connected the gas and lit the pilot light, turn on the power to your home and test to make sure the system is working the way you would like it to.
