How to Install Propane Pipes

Once a new propane tank or furnace is placed in your home, you must add some lines. Installing propane lines can be a dangerous and somewhat challenging project. Gas lines allow for the movement of propane gas from the source to the distribution point. When the gas arrives at the furnace or stove, it can heat the device. Therefore, installing propane lines correctly is very important in efficiently using your propane-fueled product.

Propane can help heat and fuel a furnace or stove in your home.
  1. Use a tape measure to determine the distance from the propane tank to the destination point. The destination point is where the inlet of the gas line rests, not necessarily the actual device. Write down the measurement so you will know how much copper tubing you need to purchase. Run the copper tubing from the tank to the appliance.

  2. Place the nut onto the end of the copper tubing on the appliance end. Your appliance should have a "Gas In" connection toward the back where the tube will connect. Insert the ferrule into the connection on the appliance back and then place the nut on the connection. Tighten the nut using a wrench.

  3. Connect the opposite end of the tubing to your propane tank. The tube will connect to a "Gas Out" connection valve. Place a nut on this end of the tubing and tighten it with a wrench. Ensure the inside appliance is turned off and no fire is around.

  4. Bury the line outside your home. The ditch length depends on how far away the propane tank is from your home. Dig a 12-inch-deep hole from the tank to the inlet into the home. Dig the ditch along an area where there are no obstacles, like trees or sidewalks.

  5. Fill in the ditch with 2 inches of masonry sand. Place the gas line in the ditch and fill it tightly with sand. Fill in the ditch with the dirt from Step 4 and use extra fill dirt if necessary. Pack down the dirt to help it settle more quickly.


  • Burying propane lines may be against regulations in some ares. Check with local codes before continuing with this project.
