Ceramic burners

The Ruby Fires ceramic burner is a revolutionary product which is able to create a vent less fire using a ceramic burner! The big difference between our ceramic burner and other burners on the market is that the Ruby Fires ceramic burner contains a ceramic core that slowly absorbs the liquid fuel. This causes the burner to not burn the pure liquid, but the harmless gas it releases, thus making the fire burn more gradually. The result is a safer and cleaner burner, which is easy to ignite and gives a beautiful consistent fire. Ruby Fires has the exclusive, worldwide patent on this system. Please contact your local dealer for availability in your country.

Our ceramic burner uses a liquid fuel that is much more environmentally friendly than wood or gas. There is no need for a flue to dispose of hazardous fumes, which makes this system ideal for apartments, homes, restaurants, hotels and offices; basically any location that needs the cosiness of a fire without the smoke and ash. We also supply burners which are especially designed for your garden! Our burners are very easy to place and move around as they do not require a fixed connection point. Our ceramic burner can be customized to your needs or it can be combined with one of the many surrounds from the Ruby Fires collection. For inspiration, please check our special page on our made-to-measure projects.

Our Ruby Fires ceramic burner is very safe in use as the ceramic core completely absorbs the liquid fuel and also closes off the burner. Therefore, it is impossible for the fuel to run or leak out of the burner, even when it is held upside down! Don’t believe us? Please check out this demonstration video to see for yourself.

The maximum duration of the fire of a ceramic burner is around 3 – 4 hours when the burner is completely filled, depending on the type of burner. Specific fire times can be found in the description of each article in the collection.

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

You ignite the 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. 

Yes, it is possible to place decorations on the ceramic burner if they have been specially designed for this purpose! Check out the Ruby Fires assortment for accessories which are specially developed in combination with our ceramic burners.

Yes you can. However, the ceramic 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. Surrounds Silo, Milano and Salerno from the Ruby Fires collection are delivered including a protective cover.

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 ceramic burner. The heat released from the ceramic 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.

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

There can be several causes for low flames:

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

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

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.

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 by the draft/wind
3. You are not using the CL100 fuel. Any other fuel may cause the flames to become higher than normal.

A fully stocked ceramic burner will burn between 3-4 hours. In a large burner is will go more combustible, the burning time is approximately similar.

• 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 ceramic burner while it is lit. The 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 fuel which contains more than 96% alcohol. This is the purest fuel available, which makes the combustion completely pure (without hazardous smells and remains) and produces a nice yellow flame.
• It is not the pure liquid fuel that burns, but the evaporation of the fuel from the ceramic core when it is exposed to the air. The gradual combustion makes the ceramic burner completely safe and economic in use. There is no need for a flue as there are no hazardous fumes.
• The burner is surrounded by an additional outer reservoir for extra safety. This is filled with ceramic wool, which absorbs excess fuel in case the burner is over-filled.
• This unique burning principle has been developed by Ruby Fires, worldwide patented and carries the DIN 4731-1 quality mark.

One of the advantages of a ceramic 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. The burners have a capacity of 2 – 3.5 kW, depending on the size of the burner. Specific capacities can be found in the description of each article in our collection.

In the user’s manual you will find a complete description on the maximum volume and how to fill the ceramic burner correctly. In short: The 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 fuel is visible through the hole (maximum level of 1 cm underneath the surface of the ceramic core).

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

It is important to place the decoration (ceramic logs or pebbles) around the burner-opening. The decoration should not touch the flames directly, at all times, in order to keep the combustion of the fuel as pure as possible. When the decoration does come in direct contact with the flames for an extended period of time it may cause a smell, soot or damage to the insert. 

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 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 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 burner is used with decoration (ceramic logs or pebbles)

Yes! The Ruby Fires ceramic burners are perfect for made-to-measure projects and can be tailored to your specific wishes. Please take a look at our completed projects page for some inspiration.

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 via small channels.

This is probably caused by too much fuel in the burner. When a burner is overfilled, the liquid fuel will flow from the inner reservoir into the outer reservoir. Check whether there is any 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.

The ceramic 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. 

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).

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).
