A: Our X400 burner fits exactly the same and is a direct replacement. - Q: What is the maximum output of an X400 burner? A: The X400 will deliver around 36 kW maximum depending on the particular boiler resistance. This is burner output, not boiler output, so the largest boiler output the X400 could fire would be around 32 kW. Contact our technical department for help matching a burner to a boiler. - Q: What are the B4 and S3 terminals for on the X Series burner? A: There are 5 terminals on the X Series domestic oil burner. 3 are inputs: N (Neutral), Earth and L (Live). 2 are outputs. B4 gives an output for a burner run light if you have one on the boiler panel, otherwise it is not used. S3 gives an output to a remote lockout light if you have one on the boiler panel, otherwise it is not used. - Q: The X Series mounting flange does not fit onto a Danesmoor boiler. What should I do? A: You can discard the mounting flange as the Danesmoor boiler has a mounting tube that fits the X Series and fastens down using 2 grub screws. - Q: What is the foam insert in the X Series air intake for? A: This is an acoustic foam insert to reduce burner noise. - Q: What is the steel rod and blue plastic tubing for in PN modulating burners? A: These are used for modulating the air and gas ratio of the burner. They must be fitted for the burner to operate correctly. - Q: Why do you ask installers to call about the blast tube insertion depth on commercial burners? A: All burners are range rated and can fire a range of outputs, which changes the flame length. Different boiler designs need the blast tube inserted at different depths. If the burner is not set at the correct depth, the flame could hit the back of the boiler and cause damage in the long run. - Q: How do you convert a BFP11 pump from 1 to 2 pipe operation? A: Remove the four 4mm hexagonal screws from the face of the oil pump. Remove the 2.5mm hexagonal screw at six o'clock on the bottom face of the pump. Underneath it is a copper horseshoe washer: for 2 pipe operation, remove this washer. Replace the screw and reassemble the pump, taking care not to trap the pump face gasket. - Q: Can the X Series burner run on gas oil? A: Yes, but the burner will need adjusting because gas oil needs a higher oil pump pressure for correct atomisation. Increase the pump pressure and reduce the nozzle size to keep the same output. Some modern condensing boiler manufacturers do not permit gas oil on their appliances. - Q: What bio fuel will the X Series fire? A: The X Series has been tested and is guaranteed up to a 10% mix of FAME and kerosene or gas oil. - Q: Can I use my own bio fuel? A: The X Series and components are not covered by guarantee or warranty when using untested and non-refined fuels. Warranties only apply to bio fuels refined by known oil supply companies where the fuel has been mixed and filtered to industry standards. - Q: What should I set the combustion to on X Series burners? A: Check the boiler manufacturer's instructions for nozzle size, pump pressure and CO2 levels. A typical CO2 reading is around 11.5%, which still gives a good amount of excess air. Readings over 12% CO2 will most likely cause sooting of the boiler. To calculate excess air from your oxygen reading: measured O2 x 100 / 21. For example, 6 x 100 / 21 = 28% excess air. ## Optional - [XML sitemap](https://www.eogb.co.uk/sitemap.xml): Every public page on this site. - [FAQ page](https://www.eogb.co.uk/frequently-asked-questions/): Full questions and answers.
