Outdoor kitchens are an excellent addition to any home. Building an additional structure outside our homes can get complicated, especially if they require utilities. The question now is, what is the appropriate gas line size for an outdoor kitchen?
A gas line connected to an outdoor kitchen should be ½ – ¾ inches. The main gas line pipe should be 1¼ inches; the smaller tubes are used to better transport gas to appliances. Generally, your pipe size will depend on the kitchen appliances and their distance from your main gas line.
What’s essential for a gas pipe is that it can quickly meet the consumption of appliances. For an outdoor kitchen, you’ll need to emphasize safety and protection for your lines alongside other
What size gas line for an outdoor kitchen?
Before anything else, consult a building official regarding this type of project. Unlike water lines or electricity, gas lines are much stricter in regulation due to safety concerns and thus might require a professional to install, depending on your location.
Even if you won’t be personally working on the project, it still helps in cutting costs to purchase the materials yourself. The determining factors for the correct size of gas pipes are based on the following:
- Type of Gas
You will either be going with natural gas or propane gas. Natural gas is an excellent option if it’s available in your area and your home is already connected to a pipeline. However, this isn’t an option for everyone, as having a natural gas pipeline available depends on your location.
Propane is the cheaper and more cost-efficient option compared to natural gas. Aside from being more affordable, it’s also much more versatile in use, considering that you can easily change how it’s connected to your home. The main problem with propane is that it needs to be constantly refueled.
- Appliances used
Different appliances need different amounts of gas to operate correctly. For example, a burner requires much less gas than an oven. Knowing this, manufacturers establish a certain amount of gas needed for the appliance to work.
With that, gas is measured in terms of cubic ft per hour, while an appliance’s gas needs are rated based on British thermal units( BTU). BTU divided by 1000 will more or less give you the amount of gas needed to be supplied to that appliance.
- Length of gas pipe
We also need to consider the distance between your gas source and your appliances. Combining the length and diameter of a pipe gives us its volume, and as such, this determines the amount of gas that your lines will carry.
This can be quite a significant factor for an outdoor kitchen, considering that your appliances will be separate from your home. In most cases, ½-inch and ¾-inch diameter pipes should still work within 10 – 20 ft. You might have to go towards the larger end for those using natural gas.
We’re primarily concerned with the performance of the output that we get from our pipes. Too much or too little gas is a potential hazard for your kitchen. Aside from performance, we also have to work on the safety and durability of our gas pipes.
When it comes to gas lines, safety is a top priority. The last thing we want is gas leaking out, which can explode or cause other health complications if left unattended. Luckily, the outdoors is relatively safer as any leaked gas won’t be confined to a room.
Regardless, we must consider how our pipes are built to anticipate how they will react to the environment. It saves a lot in terms of construction and maintenance if we design our additions to our homes with compatibility in mind.
- Material Choice
Firstly, the gas pipe’s material will be either copper, galvanized steel, or brass. The material used will depend again on the building regulations set in your area.
The material you choose matters as each has its properties that react differently based on its immediate environment. You also need to have your pipes fitted with the necessary protection against moisture, water, wildlife, etc., to ensure they last.
- Pipe Layout
Secondly, the gas line’s route design should also be up to standard. Guidelines stipulate how a gas line should be constructed and connected to your appliance. For example, flexible pipes are limited to short distances.
You can only use around 3-6ft of flexible piping for outdoor kitchen appliances. A flexible pipe is a great option, especially if you live in an area vulnerable to earthquakes.
These two factors affect how your gas lines will fit into your home. Understanding the pipe layout is essential for most homeowners so that you know how to operate your gas in case something goes wrong.
In some cases, installing a new gas line for an outdoor kitchen is just too impractical for some people. The additional expenses and worth might be too much for most people’s budget.
As an alternative to gas, you can opt to get electrical appliances. Electrical appliances are a great option because electrical wiring is cheaper than gas piping and much more convenient to work with. This might be a better choice if you plan on renovating or making future changes to your outdoor kitchen.
The only problem with electrical appliances within an outdoor kitchen is environmental factors. Electrical appliances are much more vulnerable than our standard burners, requiring safety features like GFCI.
Another thing to consider is outdoor foods (Ex. BBQ, Steak, Marshmallows, etc.) tend to be cooked over fire rather than induction.
Gas pipes connected to appliances should be ½-inch to ¾-inch in diameter. The distance, appliances, and type of gas used in your outdoor kitchen will determine the appropriate size for your gas line. Aside from just measurements, material choice and piping layout play a significant role in how our lines. Homeowners can also use electrical appliances if installing a gas line is too impractical.
