How To Change A Butane Gas Bottle?

Yes, you can call your local Calor Centre for advice on how to return or organise for a collection of your gas bottle. Their contact information can be found on our Calor Centre website.

How do you remove the orange cap on a butane gas cylinder?

The valve fitting on the CALOR Butane gas cylinders is 21mm. If you’re not sure, look at the diameter of the fitting on the underside of your regulator.

Step 5

Turn the switch anti-clockwise to the ‘on’ position when you need to use the gas.

We strongly recommended that you follow the manufacturer’s instructions before installing any gas regulator. The majority of snap-on regulators work in a similar way, although there are a variety of styles to choose from. When you’re done using your appliance, go back to Step 5 to turn off the gas.

Note: If you discover that turning on the supply requires too much force, you may need to redo Steps 1–5 because the regulator may be installed incorrectly.

How does LPG work?

When you turn on your appliance and release some of the pressure in the gas bottle, it transforms back into a gas.

A regulator guarantees that a constant pressure is provided from the gas bottle to your appliances in a safe and efficient manner.

How are the gas bottles connected to your home?

The gas bottles are connected to a changeover valve by “pigtails,” and the changeover valve is connected to a regulator.

Who provides the regulator, changeover valve & “pigtails”?

The gas regulator, changeover valve, and “pigtails” are installed by a licensed gas fitter hired by the property owner.

The gas fitter also connects your appliance’s gas connection to the regulator (s).

All of this would have been completed if you had recently moved into a property that already had LPG.

Automatic changeover switch valves

Automatic changeover valves employ a visual indicator to indicate when one gas bottle is empty and the valve has switched to the other.

The manual switch method, on the other hand, will not serve as a reminder to order extra gas, so be sure to check your gas bottles on a frequent basis.

Manual changeover switch valves

1. Turn the empty gas bottle’s hand wheel off (clockwise).

2. The changeover valve lever is then moved to point towards the other (full) gas bottle.

3. On the full gas bottle, turn the hand wheel ON (anti-clockwise).

4. Don’t forget to order a replacement gas bottle in case you run out.

5. Please note that the lever (blue) is pointing upwards in the illustration only to make it more obvious.

It would be placed to the left or right in practice.

Can you exchange a flogas bottle for a Calor gas bottle?

Are the clip-on regulators and Butane bottles interchangeable? A. The clip-on regulators from Calor and FLOGAS are both low-pressure 21mm and entirely interchangeable.

How does a gas changeover valve work?

We’ll be discussing how an automatic non-OPSO 2-way changeover works for the sake of this blog. For example, our M254; nevertheless, if you require assistance with another model, please do not hesitate to contact us!

When the reserve gas cylinder is empty, the transition will automatically begin drawing LPG from the reserve gas cylinder, ensuring that your gas supply is not interrupted.

The changeover will display red on the little window on the front of the valve to indicate that it has had to swap cylinders. This means you’ll need to place a new order for a replacement gas cylinder and arrange for it to be installed.

When the new cylinder has been installed, switch the lever to the other cylinder. This will remind you that you have an empty cylinder and which one needs to be replaced.

Once you’ve inserted the new cylinder and repositioned the lever to the side it’s now drawing from, the indication in the window will turn green, ready to change red when it’s time to empty it.

Can I transfer gas from one bottle to another?

To fill a gas bottle (fill propane tank), it must have a current inspection date, regardless of which of the LPG gas bottle refill techniques is utilized. Before refilling an LPG gas cylinder, the refill technician must double-check the inspection date stamped into the neck ring of the gas bottle.

Gas bottles that have passed their expiration date cannot be refilled until they have been re-inspected and marked with a new inspection date.

How to Fill a Gas Bottle Refill Using Digital Scales

Using digital scales to fill an LPG gas cylinder (fill propane tank) ensures a proper and safe refill. The gas bottle refill is complete when the total weight equals the empty weight plus the required LPG gas bottle refill weight.

The scales are calibrated for each refill LPG gas cylinder based on its empty (tare) weight and the intended LPG gas bottle refill content weight when full.

(See the illustration on the right)

How the Scales Work

The bottle manufacturer stamps the tare weight (empty weight) inside the neck ring.

After entering the weight, the technician attaches the gas bottle (propane tank) to the LPG supply.

After achieving the target weight, the digital scale immediately stops the refill LPG gas cylinder.

This provides a precise gas bottle refill, preventing dangerous overfilling or value loss due to underfilling.

The accuracy of LPG gas bottle refilling accomplished is why digital scales are the recommended technique of filling a gas bottle.

This is how large suppliers, such as SWAP’n’GO, fill a gas bottle, which is unsurprising (fill propane tank).

Faster Way to Fill a Gas Bottle (Fill Propane Tank) with Carousels

Filling a gas bottle (filling a propane tank) with scales has the added benefit of speed. To fill a gas bottle faster, the LPG supply line can be driven by a pump.

With decanting, this is not possible since the operator may be too sluggish to halt the gas bottle refilling process, resulting in dangerous overfilling.

High-speed carousels, such as the SWAP’n’GO carousel in the accompanying image, can also be used to fill gas bottles (fill propane tank) using digital scales and pump-driven LPG.

Even the keypad step can be automated in fully automated factories with gas bottle refill carousels.

The carousel digitally reads the tare weight as well as the rest of the gas bottle’s production characteristics from an RFID chip on the cylinder.

Decanting Method to Refill LPG Gas Cylinder – Fill Propane Tank – How to Transfer LPG Gas from One Clinder to Another

The decanting procedure is used to move LPG gas from one cylinder to another. If you’ve ever witnessed a service station replenish an LPG gas cylinder, you’ve seen the process of decanting. After connecting the gas bottle to a bigger LPG storage tank, the skilled operator fills the gas bottle (fill propane tank) until gas leaks from the loosened bleed screw.

As soon as liquid LPG starts to come out of the bleeder opening, the operator is obliged to stop refilling the LPG gas cylinder.

With the digital scale method, this intentional venting of gas into the atmosphere during the refill LPG gas cylinder is prevented.

Depending on the gas bottle and the person filling it, decanting can result in overfilling or underfilling LPG gas cylinders, as well as correct refill LPG gas cylinders.

The gas bottle could easily become overfilled if the operator is hesitant to stop the gas bottle refill when the liquid LPG starts to flow out.

Overfilling a gas bottle, as previously stated, is a huge safety danger.

Filling Gas Bottles at Petrol Stations

The decanting procedure is used to fill gas bottles at gas stations. The skilled operator begins filling gas bottles at petrol stations after connecting the gas bottle to a larger LPG storage tank, until some gas leaks out of the loosened bleed screw.

Dip Tube Variation Effect on Gas Bottle Refill

There can be discrepancies in dip tube lengths in addition to operator performance variances in gas bottle replenishment. Dip tubes may be missing or have fallen out of the valve’s bottom.

The operator of a refill LPG gas cylinder opens the bleed screw to fill a gas bottle until the level of LPG reaches the bottom of the dip tube, at which point liquid LPG begins to bleed out.

The worst-case scenario is a missing dip tube, as the entire ullage space would be filled, leaving no opportunity for expansion.

This is one of the reasons why swapping is a much safer option, because dip tube variations have no bearing on filling a gas bottle by weight.

% Oversized for Expansion

LPG bottles are designed to be filled to the brim while allowing 20% of the space, known as “ullage,” for natural LPG expansion.

Gas bottles that are properly filled and have the required 20% ullage should never have an issue.

Overfilling is Unsafe

When a gas bottle is overfilled, it has less than 20% ullage, which might result in gas being released into the atmosphere through the pressure relief valve.

The pressure relief valve is included into the bottle’s primary gas valve.

It’s a valve within a valve that protects against severe overpressure.

As a result, overfilling mixed with heat can cause gas to vent from the pressure release valve, posing a serious safety danger.

How to Fill a Gas Bottle Refill(Fill Propane Tank) is NOT a DIY Procedure

Filling a gas bottle (filling a propane tank) by any method should only be attempted by trained technicians. The refilling of an LPG gas bottle is not a do-it-yourself project and should never be performed by untrained persons.

The trained operators are fully aware of the required procedures, personal protective equipment (PPE), the importance of adequate clothes (including material), proper cylinder grounding, static electricity hazards, ignition sources, fire prevention, and much more.

In addition to dangerous overfilling of a gas bottle, doing so incorrectly could result in cold burns (liquid LPG has a temperature of -42°C), fire, or even an explosion.

The following is a basic message for anyone considering refilling their own gas bottles…

Can I change my BBQ from butane to propane?

Butane gas is a fantastic option if you only want to use your grill while it’s warm outside. Because butane gas may be utilized at temperatures as low as 0 degrees Celsius, it can be used in the fall and spring as well. Do you have a butane-fueled barbeque or heater that can also be used with propane? By the time winter arrives, you may easily switch to a propane gas supply by replacing the gas pressure regulator.

Can you BBQ with blue gas bottle?

What kind of gas do I require for my grill? Gas Liquefied petroleum gas (LPG) is the type of gas used in BBQs (LPG). LPG is divided into two types: butane and propane. Butane gas is stored in blue cylinders, while propane gas is stored in red cylinders, making it easy to distinguish between the two forms of gas.

Are all gas bottle regulators the same?

Please keep in mind that Propane gas cylinders have a far higher pressure than Butane cylinders, thus regulators are built for either Propane or Butane and are not interchangeable due to the difference design pressures and cylinder connections.
