Which burner to choose?

Replacing a Burner

For home heating, there are two types of boilers: wall-mounted and floor-standing. In both cases, you have the option of gas or oil fuel. To supply it, you may need an external burner, unlike a compact wall-mounted gas boiler, for instance.
If you need a burner for boiler repair or to install on a new boiler, make sure to choose the type of boiler burner you will need. We also recommend checking the overall size of the burner.
In addition to using the correct fuel, you need to know the necessary power of your gas burner or oil burner in relation to your boiler's configuration (condensing oil boiler, gas boiler, etc.) and your home's requirements. It is highly recommended to use a power similar to what is already in place to ensure economical heating and avoid energy overconsumption. For example, if you have a gas burner with a maximum of 35 kW, like the Millenium 40 G3 oil burner (or Tigra CF510R if it has a heater), there is no need to install a Cuenod NC9 H101A fuel burner that operates at a minimum power of 45 kW.

Oil Burner: Usage Precautions

Before installing an external oil boiler burner, be sure to check the size of its flame tube. It must fit properly into the combustion chamber of the boiler.
The length of the burner tube affects the type of oil nozzle in place: a nozzle on a flame tube that is too short will create a larger flame. Conversely, a flame tube that is too long, when paired with the existing oil nozzle, may produce a smaller flame. The air/fuel ratio must always be respected for the same reason of choosing the right burner: to ensure economical heating.
During the first use, for oil burners only, it is recommended to manually prime the oil pump. It will not be lubricated until the oil has passed through it. This will prevent the replacement part from becoming an item you need to buy in the future.

Boiler Burner and Spare Parts?

For the boiler, the oil burner like the gas burner requires frequent maintenance, once a year, and helps to avoid complete replacement in case of burner failure.
During boiler and burner maintenance, the heating technician must check both the overall operation of the heating system and ensure that no spare parts need to be replaced.
It is quite possible that the nozzle of the burner is no longer as effective as before, due to the continuous spraying of oil. This heating replacement part, considered a consumable, has a lifespan of about one year. The oil nozzle is not covered by the warranty related to manufacturers.
In addition to the oil nozzle, you may also need to replace the electrodes of the burner, the flame tube, or even the oil pump in place.
To ensure there is not too much soot in the oil burner, use an opacimeter and a comparative scale for the result observed on its filter paper.
For extra safety, an oil filter of the strainer type can be added. To operate your burner for the first time, consider taking our oil commissioning kit from DIFF.
