Actions to take in case of emergency

Before your call make sure of the following:
1. The gas supply valve is closed
2. The control panel is not showing fault sign

Sometimes I see condensate or ice forming on the outside surface of the LPG cylinder. What causes this?

This is called 'sweating', and is caused by the process of LPG changing from its liquid state to a vapour state. LPG in a stable state consists of both liquid and vapour. When vapour is drawn from the cylinder the vapour pressure in the cylinder is reduced and alters this stability between the vapour pressure and the pressure required maintaining the LPG as a liquid. In this condition, the liquid LPG boils releasing vapour which stabilises the pressure within the cylinder. In order for LPG to boil, it must draw in heat through the cylinder wall. As this happens the wall of the cylinder is cooled and moisture in the air condenses on the wall of the cylinder. In extreme cases, the cylinder may have ice forming on the surface of the cylinder. Interestingly, the top edge of the sweating or ice, reveals the level of the LPG remaining in the cylinder.

Why does the price of LP Gas change during the year?

LP Gas is a commodity which varies in price, depending on the supply conditions. The demand and supply availability of LP Gas causes this price change. It is normal that the price of LP Gas should rise during the winter as the increased demand reduces product availability, and that LP Gas prices should ease during the summer.

How can I tell how much LPG is left in the cylinder?

There are a number of ways to check this:
• Firstly, a cylinder can be weighed to check how much product is left in the cylinder. The weight of the LPG remaining in the cylinder is total weight of the cylinder plus the LPG, less the empty weight or tare weight, of the cylinder. (The regulator and any other fittings should be removed prior to weighing the cylinder).
• Secondly, some cylinders have gauges which show the amount of LPG contained within the cylinder.
• Thirdly, liquid crystal gauges, which stick to the outer surface of the LPG cylinder, are available, and these show the level of the liquid LPG within the cylinder by indicating a colour change at the interface between the liquid and vapour levels caused by the temperature variation.
• Fourthly, if the cylinder is being used, then it may be possible to see the level of the LPG in the cylinder by observing the level of the sweating on the cylinder wall.
• Lastly, it is possible to see the level of the LPG liquid within a cylinder by pouring boiling water down the side of the LPG cylinder. The liquid level is revealed where a condensate or frost line occurs.

Where should I store my LP Gas cylinder?

Your LP Gas cylinder should be stored in a location which is well ventilated and accessible so that it is easy to change. Remember that the hose connection to the appliance should not be excessively long as this will make the hose prone to damage. In addition the LP Gas cylinder should not be in direct sunlight or located close to any direct heat source such as an open fire. Always ensure that the LP Gas cylinder is stored in an upright position. --> Go to top

Sometimes the flame on the appliance is not at a constant height and varies. Why does this happen?

This can be caused by several reasons:
• The cylinder is low on LPG and will need refilling soon.
• The draw-off rate is greater than the cylinder can deliver.
• The regulator is wrongly sized for your application.
In all cases you should contact your supplier for a refill, or inform your supplier about the application requirements.

What to do if it smells gas?

1. Check if any of equipments valves is open.
2. Check all flexible hose.

What to do if I hear the gas alarm sounder?

In case you have gas control panel fixed, check which zone it is showing on the screen and check that zone.
In case you have independent leak detectors check the area around the source of sound.

I don’t have gas supply what to do?

Check if all necessary valves are open, and check if you have enough quantity of gas in your tank or cylinder.

How to check joints for leak?

By using special detection spray or by using soap, never use fire.
