Liquid fuel CL100

What is bio-ethanol fuel?

Ruby Fires fuel is made from the fermentation of sugars in sugar cane, wheat, sugar beet, or corn. In order to stimulate this process, yeasts are added as production-organisms. Worldwide regulations dictate that liquid fuel in its purest form (100% alcohol) cannot be sold. Therefore, Ruby Fires developed a fuel that contains more than 98% alcohol: CL100. The remaining ingredients consists of materials that create a beautiful yellow flame during combustion. CL100 is the purest fuel available and is produced in the Netherlands.

The CL100 fuel is not suitable to use in all burners with an open reservoir. The fuel is developed for the ceramic burner in particular but can be used in our latest open burner models. The ceramic core absorbs the liquid fuel, which evaporates when exposed to the air. This means that it is not the pure liquid fuel that burns, but the vapour that comes from the ceramic core.

Can I also use another type of fuel instead of bio-ethanol?

No, we strongly advise against the use of any other fuels. The reason herefore is that the ceramic core will absorb this other fuel and will cause an impure combustion. This may cause an unpleasant odour and unnecessary smoke and soot production. Moreover, it may cause the ceramic core to get clogged by the chemical supplements in these (less pure) fuels, which in turn will prevent a normal combustion. As a result, in the long run the core might not be able to absorb fuel anymore. Using different fuels also cancels the warranty on the burner. We therefore advise you to use CL100 fuel, which has been specially developed for the ceramic burners. 

The fuel is leaking out of my ceramic burner

Dry the burner with a piece of cloth and leave it for a while to make sure that most of the fuel is either absorbed by the ceramic core or has evaporated. Check if there is no fuel in the outer reservoir by holding the burner upside down. Make sure to only do this outdoors and only do this when you are certain that the burner is extinguished, cooled down and has not been filled less than an hour ago. If you see fuel pour out of the burner, then it has been overfilled. You can download the instructions for restoring the burner here. Be careful that you do not overfill the burner again, please check our manual for instructions on how to fill the burner correctly. Check again after refilling whether the fuel still leaks out, if this is not the case the burner is safe to use again. It is possible that the burner was filled to quickly thus not giving the ceramic core enough time to absorb the fuel, please give the ceramic core some time to absorb the fuel before use. 

Does the bio-ethanol fuel produce a smell?

A combustion generally only produces a smell when the fuel is not filtered sufficiently and when it is produced from (too many) different raw materials. Also, the alcohol percentage is very important as the lower the alcohol percentage the more you will be able to smell it. Fuels with a low alcohol percentage contain a higher percentage of chemical supplements, which cause the combustion to be less pure. This is not the case for the Ruby Fires liquid fuel: CL100. The combination of the CL100 fuel and the evaporation from the ceramic core of the burner enable a combustion which is as pure as possible and reduces the odour. The combustion is comparable with that of a candle.

Why does Ruby Fires only sell bio-ethanol per 1 litre bottle?

When filling the ceramic burner with larger containers you run the risk of overfilling the burner. To guarantee your safety we only offer 1 litre bottles as this makes it easier to control the amount of liquid you pour into the burner.
