The total connected load (TCL) is the sum of all the gas appliances in your home that will be using the gas pipe. To determine the TCL, you will need to:
* List all of the gas appliances in your home.
* Find the gas input rating for each appliance. This information can be found on the appliance's nameplate or in the owner's manual.
* Add up the gas input ratings for all of the appliances to get the TCL.
Step 2: Determine the pipe length
The pipe length is the distance from the gas meter to the farthest gas appliance. To determine the pipe length, you will need to:
* Measure the distance from the gas meter to each gas appliance.
* Add up the distances to get the total pipe length.
Step 3: Determine the pipe size
The pipe size is based on the TCL and the pipe length. You can use the following table to determine the pipe size:
| TCL (CFH) | Pipe Length (ft) | Pipe Size (in) |
|---|---|---|
| Up to 100 | Up to 25 | 1/2 |
| 101-200 | Up to 25 | 3/4 |
| 201-300 | Up to 25 | 1 |
| 301-400 | Up to 25 | 1-1/4 |
| 401-500 | Up to 25 | 1-1/2 |
| 501-600 | Up to 25 | 2 |
Step 4: Install the gas pipe
Once you have determined the pipe size, you can install the gas pipe. Be sure to follow all local codes and regulations.
Tips for sizing gas pipe
* If you are unsure about the TCL or the pipe length, it is best to err on the side of caution and install a larger pipe.
* If you are planning to add gas appliances in the future, you may want to install a larger pipe so that you do not have to replace the pipe later.
* Be sure to use the appropriate type of gas pipe for your application. There are different types of gas pipe available, such as black iron pipe, copper pipe, and PVC pipe.
