The progressive, patented burners by Ruby Fires, bring the safest fire. The burners meet the latest standards and carry the DIN 4734-1 quality mark. The burners have been tested in accordance to criteria set by the joint European testing institutes. These criteria concern the usage of fuel, the exhaust of a minimum amount of CO2 and the functionality of the burner.
Safety comes first with Ruby Fires and all burners contain a ceramic core. This core absorbs the liquid fuel completely, which makes it impossible for the fuel to leak or spill from the burners, in contrary to burners with an open reservoir. The filling opening is separate from the opening of the fire and due to the built in safety system it is impossible to fill the burners while they are lighted.
