(3) A tank must be grounded with at least two grounding electrodes, as stated in Section 4.13, spaced at maximum 100 ft (30 m) intervals around its circumference. (4) A tank installation that uses an insulating membrane beneath it for environmental or other reasons must be grounded in accordance with Section 7.3.
Is it necessary to bind a propane tank?
The tank does not require bonding, but the structure’s pipework must. The tank, on the other hand, necessitates special clearance from the structure. I’m not sure how big that tank is, but it’s in close proximity to the structure.
Is it possible to store propane tanks on the ground?
Propane tanks can be safely stored outside, but it’s important to find a location that’s not too close to your home. It’s crucial to remember that freezing temperatures aren’t a concern for propane tanks while storing them in the winter. In fact, when storing your tank outside in the winter, you don’t even need to cover it.
Place the tank on a solid surface, such as a piece of wood or a slab of concrete, and store it open or closed.
It’s also simple to store propane tanks during the summer. During the summer, your propane tank can be kept outside on a flat, firm surface. Keep the tank in a shady spot so it doesn’t sit in direct sunlight for long periods of time. This will keep the tank at a safe temperature, but not above 120 degrees Fahrenheit (49 C).
What is the nature of propane’s bond?
Propane can be used in a variety of ways around the house and in the workplace. Propane, commonly known as liquefied petroleum gas, is a safe, clean-burning, cost-effective, and easy-to-transport energy source. We are delighted to deliver this fantastic fuel to your homes and businesses at Tri Gas & Oil. Long before it reaches your house tank or work equipment, the narrative of propane begins. Propane is a natural gas component that took millions of years to create. Propane is made up of three carbon molecules joined by eight hydrogen atoms in the chemical formula C3H8.
The carbon structure of propane gives it an organic classification. One of the most important facts to remember about propane is that it is non-polar, which means it won’t interact with polar substances like water. “Oil and water don’t mix,” your science instructor explained, and the same is true for propane and water. They’re not going to get along.
Propane is a form of hydrocarbon that belongs to the Alkane class of molecules, which are connected by single covalent bonds. Because one carbon atom is connected to four hydrogen atoms, methane, often known as natural gas, is the simplest alkane. The two carbon atoms in ethane are bound together and each is bonded to three hydrogen atoms, totaling six hydrogen atoms. It develops a chain of three carbon atoms connected with a total of eight hydrogen atoms to make propane. Butane is a gas having four carbon atoms and ten hydrogen atoms that is often used in hand-held torches.
Propane is a straight-chain alkane with a more direct composition. The outer carbon atoms connect three hydrogen atoms apiece, whereas the middle carbon atom bonds with only two hydrogen atoms, for a total of eight hydrogen bonds.
Because propane’s boiling point is -44 degrees Fahrenheit, it can only be stored in a liquid condition in a pressurized tank. Furnaces, hot water heaters, outdoor gas grills, gas-powered camping cooking stoves, forklifts, field irrigation machines, fleet cars, and even buses are all frequent propane uses.
The Science Behind the 80/20 Rule
Have you ever puzzled why your propane tank at home never seems to be entirely full when you look at the gauge?
Your propane provider wants you to know that there is a reason for this, and it has to do with safety. If you’re interested, there’s also some fascinating science behind it.
Propane tanks are only filled to 80% of their capacity, leaving 20% of your tank unfilled. This precautionary strategy is known as the 80/20 Rule, and it protects your propane tank against changing temperatures and the resulting rise in volume.
Propane expands as it heats up. When water heats up, it accomplishes the same thing. Propane, on the other hand, will grow in volume nearly 17 times faster than water. That’s a lot of room for growth! Because all of that additional liquid needs a somewhere to go, we limit fill tanks to 80 percent capacity. This empty space acts as a relief valve for the pressure that builds up inside your tank when it heats up.
Tri Gas & Oil constantly prioritizes safety, and now you know the science behind this procedure as well! Whether you want to warm up your home with a propane fireplace in the winter or have a wonderful cookout in the summer, propane is a safe and affordable alternative all year.
Overall Cost
The actual tank will cost the same whether you choose an above-ground or underground installation. An subterranean tank, on the other hand, will be more expensive up front due to the additional costs of:
- Excavation: This requires contractors to check that your foundation is solid, that the tank is at least one foot below ground, that it is securely installed, and that it is backfilled properly for safety.
- Additional labor: The building of an underground tank necessitates the use of more people and equipment, increasing labor expenses.
- Sacrificial anodes are an additional expenditure to the homeowner that are placed around the propane tank to assure long-term corrosion protection.
The additional costs of installing an underground propane tank might easily treble the cost of installing an above-ground propane tank.
In addition, underground tanks can be more expensive to maintain. Anti-corrosion coating is required for subterranean propane tanks to defend against underground factors that could damage the outer material. The coating must be inspected and tested on a regular basis to guarantee that it is functioning properly. It will also need to be replaced if the anti-corrosion coating has been weakened. The homeowner will incur increased costs as a result of these maintenance actions.
Installation Process
Before beginning excavation, just as with an above-ground tank, make sure you have all of the necessary permissions, arrangements, and safety checks in place. The procedure of installing an underground propane tank will take between 2-3 hours once excavation has begun.
You may need to contact your septic provider to dig the hole for the underground propane tank if your home has one. It’s possible that the propane delivery equipment will run over the septic tank if there isn’t enough cooperation, resulting in significant damage.

Safety of the Tank
Underground tanks are often safer than above-ground tanks. One reason is because these tanks are more able to maintain their temperature in adverse conditions, particularly in the freezing cold.
In the event of a leak, underground tanks are also safer. Propane is a green fuel, therefore if a leak occurs, it will not harm the surrounding water or soil. Unlike an above-ground tank, there is no risk of the fuel escaping into the atmosphere and igniting a fire.
As a result, depending on the weather, an underground tank is a better option. The exception to this rule is in flood-prone locations, when above-ground tanks are recommended.
What is the minimum distance between a propane tank and a house?
A basic installation takes only a few hours and can be scheduled in a matter of days, depending on the intricacy, weather, and the availability of our technician or Certified Partner. The materials to install your tank, tank bases/blocks, gas line required to install the tank (up to 10 feet from where the line enters the house), fittings to hook up to the gas line, and travel up to 80 kilometers each way are all included in the basic install package.
To ensure the procedure go as smoothly as possible, our professionals have produced the following preparation checklist.
Prepare your home appliances.
Ensure that all of your propane appliances are properly installed and vented, and that the gas line is connected to an exterior wall. The sole exception is if you live in British Columbia, where you can install the appliances after the tank has been installed, allowing your gas-fitter to perform the final connection while installing your appliances.
Make sure the ground is ready.
Gravel, cement, or a stable ground base should be present where your tank will be installed. Depending on the amount of tank you require, the ground must be level and particular clearances must be adhered to.
A 420-pound cylinder or vertical-style tank, which is our smallest permanent tank built for supplemental heating for water heaters, fireplaces, pools, and heaters, requires a clearance of 3 feet from windows and doors and 10 feet from any sources of ignition and air intakes. This tank can be positioned against a structure.
The clearance required for a 500 USWG horizontal-style tank appropriate for residential heating is 10 feet from your home, any building or structure, the property line, windows and doors, and any sources of ignition and air intakes (for example, heat pumps and air conditioners).
Each town has its own set of building codes, some require permits as well
Permits are required in some cases for tank and appliance installation. There may be a price associated with permissions in some situations; we can secure the permit. The cost, if any, is the customer’s responsibility and can be charged to your account.
Please keep in mind that we are unable to put propane tanks directly beneath decks. The installation of propane tanks under decks or areas of escape from a building or structure is prohibited under NFPA 101, The Life Safety Code. Your family is at stake if you break this code.
“8.7.3.2 Flammable liquids or gases shall not be stored or handled in any area where such storage would compromise egress from the structure… National Life Safety Code, National Fire Protection Association.
Is there a legal requirement for gas bonding?
Earth bonding is now a legal necessity for all electrical installations in rooms with a shower or bath, as of 2008. The use of a thick green and yellow copper cable to link your gas meter or consumer unit to incoming sources such as your gas pipe is referred to as “earth bonding.”
What is the difference between bonding and grounding?
Bonding. Bonding is the process of connecting non-current-carrying conductive elements, such as enclosures and structures, to one another. The connection of bound systems to the soil is known as grounding. Both are required to protect persons and property from electrical dangers.
Is it necessary to ground flexible gas lines?
To limit the possibility of damage from a lightning strike on the home, CSST flexible gas piping must be bonded.
The most prevalent problem discovered by house inspectors is that the CSST system is not properly bonded.
There is an increased danger of damage when this sort of gas-distribution system is constructed without being adequately bonded to current requirements.
Gas can leak from a damaged gas or propane line, resulting in a fire and/or explosion.
As early as 2007, all CSST manufacturers began implementing Specific Bonding Requirements.
What about houses that are already built? Grandfathering is a term used in building codes. This indicates that if anything was installed in accordance with Building-Codes at the time of installation, it will be considered appropriately installed in the future, even if the Building-Codes alter dramatically.
If CSST was placed (in accordance with code) before the specific bonding criteria were imposed by CSST manufacturers, the installation still meets code today. Based on today’s Building-Codes and Safety-Practices, a Home Inspector will (or should) define the need for a safety-upgrade. ** This is not to be confused with the fact that unbonded CSST flexible gas lines are safe. Only that it complied with construction codes at the time it was erected.
