Many people prefer to cook on a gas stove as it allows for more precise temperature control of the burners for sautéing than does an electric range. While natural gas is more convenient, as it provides a steady supply from the utility company, in areas where natural gas service is not available the only alternative is propane supplied from a tank. Installing a propane line for a stove can be done in an afternoon, but be sure to check codes for proper installation, placement and connection requirements.

Measure and plan the route for the gas line to come into the house from the propane tank to the stove. Take into account all 90-degree turns you will need to make to route the line around any obstructions such as bulkheads and water tanks. Measure everything twice before you order the pipe.

Measure the width of the recessed area at the back of the gas range and mark the measurement on the floor, against the wall. This is where the gas line must come in through the kitchen floor, so the line will not block the stove from setting flush against the wall. Use the 1/4-inch bit to drill a pilot hole. Change to the 1-inch spade bit and cut the hole for the new gas line.

Change back to the 1/4-inch bit and drill a pilot hole, from inside, through the basement (or crawl space) wall. Switch back to the 1-inch bit and enlarge the hole.

Insert the gas pipe into the wall and apply gas pipe joint sealing compound to the threads of the pipe. Join the pipe section by holding an elbow joint stationary with one wrench and turning the threaded pipe into the elbow with the other wrench until tight. Repeat for all sections of the gas line over the length of the run from the stove location to the tank.

Install the pipe hangers along the ceiling joists in the basement with the screwdriver, drilling pilot holes if necessary to start the screws. Attach the connected gas line to the hangers with the wrench.

Install the service valve at the end of the elbow in the kitchen. Install the gas line cap at the end of the line. Connect the copper gas line that will lead to the propane tank, to the outside end of the gas line. Attach the pressure valve to the free end of the copper line and pump the gauge up to three pounds of pressure and let stand for 10 minutes. The pressure should not drop. If it does, recheck all the fittings. Schedule the gas inspector, if required, to verify the integrity of the new line.

Wrap the threads of the tank connection fitting with Teflon tape and attach to the tank with the adjustable wrench. Remove the cap from the service valve in the kitchen. Wrap the threads on the service valve and the gas line fitting on the stove with Teflon tape. Hand-tighten the flexible gas line to the connections, then finish tightening with the adjustable wrench.

Tips & Warnings

  • Loosely dry-fitting all the pipe sections together before you make the final install will ensure all the pieces are correctly sized and laid out.
