Bio ethanol burners

Bio ethanol burners
• What is a bio ethanol burner with ceramic stone?

The Xaralyn bio ethanol burner with patented ceramic stone is a revolutionary product, the safest open fire! The big difference between our bio ethanol burner and other burners on the market is that the Xaralyn bio ethanol burner contains a ceramic core that slowly absorbs the liquid fuel. This causes the burner to not burn pure bio ethanol, but the harmless gas it releases, this makes the fire burn more gradually. The result is a safer and cleaner burner, which is easy to ignite and gives a beautiful consistent fire. 

• What are the advantages of a bio ethanol burner with ceramic stone?

The patented ceramic stone in the bio ethanol burner absorbs the bio ethanol completely and also closes off the burner. Therefore, it is impossible for the bio ethanol to run or leak out of the burner, even when it is held upside down! 


• Does the bio ethanol burner produce heat?

One of the advantages of a bio ethanol burner is that it produces a pleasant warmth. This heat cannot be used as a primary source of heating, but it contributes to a cosy temperature in the room. 

• How can I see if the bio ethanol burner is filled to the correct level?

In the user’s manual you will find a complete description on the maximum volume and how to fill the bio ethanol burner correctly. In short: The bio ethanol burner can be filled by placing the funnel in the filling-opening (opening in the ceramic core). The ceramic core is completely saturated when the bio ethanol is visible through the hole (maximum level of 1 cm underneath the surface of the ceramic core).

• Can the bio ethanol burner be re-filled immediately after it is burned out?

The answer is no, after use the bio ethanol burner needs to cool down for at least 30 minutes before you can refill and use it again. 

• How do I position the decoration on the bio ethanol burner?

It is important to place the decoration around the burner-opening. The decoration should not touch the flames directly, at all times, in order to keep the combustion of the bio ethanol as pure as possible. 

• Should both glass shields be used?

It is important to keep the flame stable, which can be realized by using either decoration material (ceramic logs or pebbles) or glass shields. Both glass shields need to be used when the bio ethanol burner is used in a “see-though” situation (no wall on both long sides) and no decoration material is used.

The glass shields should not (or partly) be used if:

  1. The bio ethanol burner is used in an insert or opening with a back wall. In this case you only need to use a glass shield on the front side of the burner.
  2. The bio ethanol burner is used with decoration (ceramic logs or pebbles)
• Strange smell - Bio ethanol burner in combination with concrete-look wall-mounted fireplace or surround.

In some cases, it may happen that a concrete-look wall-mounted fireplace gives a "typical" odour when it is used for the first time in combination with a bio ethanol burner. The heat released from the bio ethanol burner accelerates the drying process of the composite material of the wall-mounted fireplace or surround from which it is manufactured. This odour is harmless and will disappear after the fire has burnt a few times.

• The flames of my bio ethanol burner become higher after approximately half an hour

A reason for these abnormal flames is most likely the use of both the glass shields and placing decoration material (ceramic logs or pebbles) directly on the bio ethanol burner.

The excessive material around the fire-opening combined with an insufficient oxygen supply is known to disturb the vertical airflow. As a result, your fireplace will work similarly like a chimney and create high flames. It is hereby important to extinguish the fire, as described in the manual, and remove either the glass shields or the decoration. WARNING: The decoration material may never touch the flames.

• The flames of my bio ethanol burner are very low

There can be several causes for low flames:

  1. The flames of a new bio ethanol burner will be lower the first three to four times it is used. After several uses the ceramic core will be thoroughly saturated with bio ethanol and a steady combustion will occur.
  2. It is important to use the advised CL100 bio ethanol (>96% alcohol) as the ceramic burning system is designed and tested extensively in conjunction with this bio ethanol. When you use a different bio ethanol, the effect will not be optimal and this will result in lower flames. If you have used a different bio ethanol, you can refill the burner with the CL100 bio ethanol again. This will – depending on the amount of bio ethanol used before – cleanse the system of the previous bio ethanol, however it might take some time to burn away the previous bio ethanol and have the burner functioning properly again.
  3. Check if your bio ethanol burner is completely filled with bio ethanol. If this is not the case, please fill it up in accordance to the user’s manual. When a completely filled bio ethanol burner is not used for a while, the fuel will slowly evaporate. Thus, it is important to keep the latch closed in order to prevent this as much as possible.
• My bio ethanol burner does not extinguish when the latch is closed

When the latch is not closed quickly enough, it is possible that the fumes of the bio ethanol escape through an opening and catch fire. Re-open the latch and close it again in one quick move. If the bio ethanol burner still does not extinguish, there is probably fuel in the outer reservoir.

• There is a white haze on my glass shields

The heat of a flame can create a haze or deposit on the glass. We therefore advise you to remove this by using a special cleanser for ceramic cooking ranges. When this is done at on regular basis, it will remain easy to clean the glass.

• The black varnish on the back of my insert is coming off

If the black varnish on the back of the insert is coming off, it is most likely caused by the flames touching the back of the insert. Please extinguish your fire immediately if this is the case and consult the manual. There can be three causes for the varnish to come off:

  1. You are not making use of the glass shields or decoration material (e.g. ceramic logs or pebbles).
  2. The flames are influenced draft/wind.
  3. You are not using the CL100 fuel. Any other fuel may cause the flames to become higher than normal.
• How long will a bio ethanol burner burn?

A fully stocked bio ethanol burner from Xaralyn will burn between 3-4 hours. Large burners can hold more bio ethanol, the burning time is approximately similar.

• How does a bio ethanol burner with ceramic stone work?

Due to the fact that the burner is completely filled up by the ceramic core, it is not possible for the liquid fuel to leak – even if the burner is tilted.

Because of the built in safety device, it is simply not possible to fill the bio ethanol burner while it is lit. The bio ethanol burner can only be filled when it is closed off and therefore extinguished.

Because the burner is completely filled by the ceramic core, it is possible to use a bio ethanol which contains more than 96% alcohol. This is the purest bio ethanol available, which makes the combustion completely pure (without hazardous smells and remains) and produces a nice yellow flame.

It is not the pure bio ethanol that burns, but the evaporation of the bio ethanol from the ceramic core when it is exposed to the air. The gradual combustion makes the bio ethanol burner with ceramic core completely safe and economic in use. There is no need for a flue as there are no hazardous fumes. The bio ethanol burner is surrounded by an additional outer reservoir for extra safety. This is filled with ceramic wool, which absorbs excess fuel in case the bio ethanol burner is over-filled.

This unique burning principle has been developed by Xaralyn, worldwide patented and carries the DIN 4731-1 quality mark.

• What is the lifespan of the ceramic core?

When used correctly (see manual) and in combination with the correct CL100 bio ethanol (>96% alcohol), the burner can be used for years to come. The ceramic core normally does not need to be replaced.

• How do I ignite the bio ethanol burner?

You ignite the bio ethanol burner by opening the latch on top of the burner (you should see the white ceramic core) and holding a long lighter directly above the saturated core. 

• Is it possible to use decorative logs or pebbles on the bio ethanol burner?

Yes, it is possible to place decorations on the bio ethanol burner if they have been specially designed for this purpose! 

• Which accessories are included with the bio ethanol burner?
  • • 1 user’s manual
  • • 1 funnel
  • • 1 lighter (not with burners from the “Pure Collection”)
  • • 2 metal handles
  • • 2 glass shields
  • • 4 connectors (to hold the glass shields)
• Can I use the bio ethanol burner outdoors?

Yes you can. However, the bio ethanol burner cannot constantly stay outdoors as the ceramic core of the burner absorbs all fluids, e.g. (rain)water, and does not release this. As a result, the burner may become clogged and damaged. When the burner is used outdoors we advise you to place the burner indoors or underneath a roof after use. 

• The ceramic bricks seems to be broken/cracked

The ceramic bricks have a width of 230 mm. Therefore we need to place more than one brick next to each other in each burner in order to fill it up. You can see this by looking into the burner opening. You will see a seam in between the bricks. This has no influence on the combustion, the fuel is spread throughout each brick through small channels.

• My bio ethanol burner burns uncontrollably

This is probably caused by too much bio ethanol in the burner. When a burner is overfilled, the bio ethanol will flow from the inner reservoir into the outer reservoir. 

• How can I see if my bio ethanol burner is overfilled?

The bio ethanol burner is overfilled when the level of fuel reaches above 1 cm of the white ceramic core surface. Please check our manual for instructions on how to solve this problem. 

• How should the connectors and glass shields be installed on the bio ethanol burner?

When using the two glass shields make sure to attach the four connectors in the appropriate holes on top of the burner. Place the glass shields in these connectors, while making sure to not tighten the connectors to tightly to the frame (there needs to be a small margin between the connector and the glass shield as glass expands when it heats up).

• My glass shield is broken

If one of the glass shields is broken, it is easy to order a new one online . Please make sure not to tighten the connectors too tight and extinguish the fire when it touches the glass shield too much (see manual).

• Which burner format can I choose

A bio ethanol burner consumes oxygen in addition to ethanol. Ventilation is always required when burning a bio ethanol burner. In almost all cases, the ventilation that is already available for a healthy living environment in the house is sufficient with the following recommendations.

Recommended minimum space:
Bio ethanol burner S or M: 75m3
Bio ethanol burner L: 105m3
Bio ethanol burner XL: 120m3
Bio ethanol burner XXL: 210m3

If you want to use a larger burner in a smaller room, you must provide extra ventilation.
