Gaseous paraffins is the correct description for what we call LP gas. LP gas consists of the hydrocarbons propane and butane, or a mixture of the two. These gases are extracted from crude oil.
LP gas or LPG stands for liquefied petroleum gas. At normal temperatures, LP gas is gaseous but is a liquid when under pressure. Propane must be distributed in steel cylinders that can withstand high pressure. Butane can be distributed in lighter gas cartridges.
Leaking LP gas is a fire hazard.
LP gas is heavier than air.
LP gas uses air during combustion.
There are primarily two things to think about to prevent accidents with LP gas. 1. Avoid leakages. 2. Ensure good ventilation. Leaking. LP gas can ignite and cause a fire, or in the worst case, an explosion.
The cylinder valve should always be closed when the cylinder is not in use. The cylinder should be stored upright and, if possible, at ground level since LP gas is heavier than air and can therefore accumulate in cellars, manholes etc. Good ventilation is important when working indoors as the flame consumes air. Lack of oxygen causes incomplete combustion, which produces carbon monoxide instead of carbon dioxide. Carbon monoxide is a treacherous and deadly gas.
Permits very high power outputs.
Energy content is high.
Fuel is easy to store and transport.
A large amount of fuel only occupies a small space and is therefore easy to store and transport. LP gas forms a combustible mixture with air when the proportion of gas is between 2 and 10 percent.
When the gas changes from a liquid to a gaseous form, the volume increases by 250 times. In other words, the energy content is high. LP gas can be stored in its container almost indefinitely without the gas breaking down.
LP gas is non-toxic and does not contain hazardous additives.
It does not contaminate air or water.
LP gas does not produce any hazardous combustion gases, just carbon dioxide and water vapor. The gas does not contaminate water, it does not produce soot, it is not corrosive and it does not cause corrosion to iron or other metals. It does not contain lead or heavy metals and is non-toxic. In other words, LP gas is an environmentally
friendly fuel. The only additive is a strongly smelling substance that acts as a warning signal for leaking gas. Normally, LP gas has no smell.
Work in well-ventilated areas.
Avoid placing the LP gas cylinder near sources of heat.
Ensure that the cylinder is stored upright during transport.
You should regularly check valves and connectors for leakage. Remember also that good ventilation is important at areas where the gas is stored or used. Ventilation is also important to ensure effective combustion. Make sure that the cylinder is at ambient temperature when you begin working. If you are going to use the fuel at temperatures below zero Celsius, use propane instead as butane does not gasify at low temperatures.
Always extinguish LP gas fires with powder, never water.
Move LP gas cylinders to a safe place if there is a fire in the vicinity.
If possible, close the valve on the cylinder.
Steel cylinders are fitted with a safety valve that opens if the pressure increases too much. This can occur if there is a fire close to the cylinder. The valve stops the cylinder exploding. To guarantee the function of the safety valve, it is important that the LP gas cylinder is stored in a standing position. In addition, a closed valve stops unchecked gas flow if a hose should become damaged.
Never allow an untrained person to use the equipment.
Only use special LP gas parts.
Be extra careful with valves and connectors.
Never use other valves, burners or hoses that those designed for use with LP gas. Sievert LP gas hose conforms to the EN 559
standard. The hose consists of an internal rubber layer that is LP gas-proof, armouring an external rubber layer that can withstand air and aging. All equipment shown in this product catalogue is manufactured of materials that withstand LP gas and is designed so that the risk for leakage is minimal.
Ensure that you have the correct equipment for the job. Make sure that you have tightened all valves and connectors.
Regularly inspect the equipment and check that the system is sealed.
Read the instructions for use and follow the safety advice. Use soapy water or a special liquid for detecting leakages on valves
and joints to find any leaks. LP gas hoses should be checked verycarefully and changed if you see any changes. Bend the hoses and look for cracks in the rubber. Hoses exposed to sunlight with age quicker that those used indoors.
LP gas is not affected by long storage periods.
Always disconnect equipment form the container.
Store the cylinder in a well-ventilated area.
Avoiding storing LP gas cylinders in areas that are warm. Temperatures below zero Celsius are, however, perfectly safe for storage. Ensure that the ventilation is good. In principle, LP gas can be stored indefinitely in its container without the quality being affected. Remember to remove all connectors before storing the equipment. To empty the system of gas, close the valve on the LP gas cylinder. Then close any valves on the rest of the equipment. In this way, you will avoid LP gas spillage when you open the system again.
When LP gas turns from a liquid to a gas, heat is required which is taken from the liquid itself, from the container and from the surrounding air. LP gas and the bottle become cooler which reduces the pressure in the container. For larger burners, and especially during continuous use, a sufficient container size is necessary so that the burner can work at a constant power. When using larger burners or burners with high gas consumption, ensure the cylinder size is large enough to deliver the required gas, without significant temperature drop. Table below shows an example of the maximum quantity of gas possible to use during on hour for burners requiring 2 bar pressure. Conditions for this example are the following: gas – propane, cylinder size 11 kg, continous gas use during one hour, temperature of air and cylinder.
Temperature +20°C 0°C
Full cylinder 11 kg propane 3.80 kg 1.60 kg
Half cylinder 5.5 kg propane 1.90 kg 0.85 kg
For large gas burners you need to have big gas cylinders with enough gas or several cylinders linked together.
Theoretically, LP gas has a maximum flame temperature of 1925 °C. In practice, this temperature is not reached when heating an object. The temperature achieved depends on the size of the object, how much heat is dispersed, the ability of the burner to transfer heat, the size of the burner and how long the object is heated. Therefore, the choice of burner depends on the job to be carried out.

- 293002 DW 3000 UK 120V – Over 100V
- 293047 DW 3000 US 120V – Over 100V
Alternative 2: Use shorter and thicker extension cords to prevent big voltage drops during operation. Recommended cable thickness is 2,5 mm2 (AWG 14) and minimum 1,5 mm2 (AWG 16).
EU: Voltage drop per 10 m 1,5 mm2 cable is 2,0V
EU: Voltage drop per 10 m 2,5 mm2 cable is 1,3V
UK and US: Voltage drop per 10 m (33ft) AWG 14 cable is 2,5V
UK and US: Voltage drop per 10 m (33ft) AWG 16 cable is 4,0V
Alternative 3: If operating with low incoming voltage power, use a lower fan speed setting (1-2). Push the fan button on the tool to lower the fan speed. There are 3 different speeds, you should lower to 1 or 2.
Alternative 4: Check to see if there are other power sources with big loads plugget into the same grid. This can be the source of the grid disturbance and recurring voltage dips.
