How Do I Connect My Propane Grill to My House

This article will help you learn how easy and economical it is to connect your grill. The cost of securing your propane grill is very minimal, and this article will show you just that.

Tools and Materials

  • Gas grill with availability to connect to a 1/2″ copper flexible gas line
  • Teflon tape and joint compound for the connection between the grill and the flexible line
  • 1/2″ x 3 ft. aluminum or steel pipe nipple (the cooking grate or frame is resting on)
  • 1/2″ close nipple (threads inside of both ends)
  • 1/2″ MIP x FIP connector (connects the hose to input valve on gas regulator)
  • Thread sealer —Teflon tape and joint compound; usually comes in a kit at hardware stores and is very cheap—and some pliers will be needed as well
  • Adjustable wrench or channel lock pliers
  • Philips head screwdriver, drill with 2 1/8 inch spade bit, 1/2″ spade bit, 1/2″ torpedo level, a crescent wrench for the adjustable wrench.

A Step by Step Guide on How Do I Connect My Propane Grill to My House

Step 1: Determine

This is an essential first step to ensure you have the correct length of the flexible gas line. Next, the distance between your grill and house should be measured from the backside of your grill (opposite side from where the regulator will be) to the wall or window behind it—not including anything in between such as porch steps or other obstacles.

Ensure You Have Enough Gas Line

Step 2:  Purchase

Purchase the flexible gas line and the pipe nipple. The length of the flexible gas line does not need to be perfect, but it should be long enough to serve its purpose—this is where your measurement from Step 1 will come in handy.

The length of the pipe nipple will depend on how far apart your house and grill are; for example, if they are ten ft. apart, then purchase a three ft. length nipple instead of a one ft. one, so there will be room to work with. You might want to cut about 2 inches off later anyhow, so don’t put too much thought into this step either because you may have excess leftover pipe material if cutting turns out to be necessary.

Step 3: Clean Up & Mark Your Line

The flexible gas line and the pipe nipple both have an input and output, which you will need to line up for them to fit together easily. The input end of your flexible gas line should be marked with a small arrow or triangle—this marks where it needs to be connected at its tip because the other end has the other component that screws into it, which you do not want right now.

Mark another lot, so you don’t get confused later when things are already put together. The thread tape should be wrapped from one side of the male component to the other several times; this is important for a good seal against leaks. If using joint compound, apply generously on any exposed threads and where they meet the nut and tighten with pliers.

Step 4: Attach New Pipe Nipple to Floor of Grill

The new pipe nipple needs to be attached with a small bolt or screw because it will need to withstand cooking heat and temperature changes from outside weather conditions. Turn your propane tank off at this time if you haven’t done so already.

Next, unscrew any bolts from the cooking grate frame, insert the long pipe nipple through the bottom of your grill floor with the output end facing up, and then re-tighten all bolts. This is a crucial step in how do i connect my propane grill to my house.

Step 5: Connect Flexible Gas Line to Input End of Propane Regulator

A threaded connection will be used for attaching flexible gas line input end onto regulator input side—this is the opposite of what you see on most common household appliances.

Attach one end of the flexible gas line onto the input “IN” valve next to the propane tank input fitting, and then use an adjustable wrench or channel lock pliers to tighten it securely. If there’s no output on the other side, screw the remaining open piece directly into your grill floor pipe nipple—it should go in quickly but be cautious not to cross-thread.

Step 6: Connect Flexible Gas Line to Grill Input

The flexible gas line needs to be connected with the central part of the regulator at its other end, which will meet up with a threaded connector already attached to your grill wall or window—the location might vary depending on where you want it to be.

The regulator may have a nut on the other end that can be tightened with an adjustable wrench or channel lock pliers after the flexible gas line is attached—make sure to not over-tighten it, which can cause damage. If needed, use a screwdriver or drill for an easier installation—the metal used in most grills is thin and easy to puncture, so work carefully and slowly when attaching this part of the flexible gas line.

Step 7: Open Valve & Test Connection

Your grill should now be connected to your house’s main propane supply! Turn both manual valves (on the propane tank and at a wall) halfway open for a temporary seal, then plug in your new fitting and turn it on. Press the red release button on the regulator first to check for leaks, then press the green air release button, which should have some indicator light on it. If everything seems fine with both buttons out, you are ready to start cooking!

Step 8: Finalize Details

Both manual valves will need to remain in the open position until your propane tank is empty or you are done using your grill. Keep everything well maintained, and don’t forget to always check the gas supply hose for leaks before turning on any units; also, make sure no foreign objects obstruct its path! If you have any uncertainties, feel free to ask a professional for safety first! These steps will help in how do i connect my propane grill to my house.

First and foremost, do not attempt to connect a propane grill to your gas system if you are unsure of what you are doing. Do not smoke or have an open flame nearby when working on the project.

Be sure that other people in your household understand these warnings as well. Always follow all manufacturer’s instructions carefully before beginning the process, and always work with unopened tanks so that smell does not escape into the air around your house.

Two standard models of propane connection include attaching the propane line to an outside wall, typically through a hole in the exterior wall or something similar, or running it up onto the roof where it can be attached without creating any gaps in the walls. How you wish to run the conduit will depend on the appliances you are connecting to your home system.

You must check with your local building department before beginning any construction on your exterior walls.

Some cities have restrictions on what can or cannot be done, especially if you plan to cut into an outside wall or attach something permanent to an exterior wall. You do not want to spend time and money working on this project only to find out later that you need special permission for it.

Legal Requirements

Almost every state has strict laws about how propane grills must be attached at the tank level and the house level. How these rules vary depends significantly upon where you live, but most places require that regulators be installed on each grill at the point where the tank is attached.

In addition, your home system should have a shut-off valve so that if someone accidentally disconnects the propane line from one of the appliances, it will not be turned on and produce a potentially dangerous situation.

Some Homes Have Used Copper Piping

Most homes have a flexible rubber hose going from each appliance to the exterior wall where the grill is located. This line should have a brass fitting with an O-ring inside to connect it to your gas system. It would help if you never switched these hoses with anything else, as this could cause an unsafe connection, leading to leaks or even explosions.

Some homes have used copper piping instead of rubber hoses, but either way, metal parts must be used for safety purposes. How you attach these lines also vary depending on your city’s building department.

Still, most will require the pipes connected with metal-to-metal fittings, which are permanently connected. How these hoses connect to the appliances is also essential for safety purposes; you should not attach them with any plastic pieces, as this might lead to leaks or explosions if there is a problem.
