BURNER INFORMATION & TIPS
After you receive your Bairan Waste Oil Burner it should perform perfectly.
7 Pin plug connections should be as the photo below:
If you have an external thermostat, e.g. room stat or wireless thermostat, remove the brown link wire. It should be wired in those connectors T1 & T2 where you removed the link.
The photo below shows the wiring of the plug attached to the burner.
For STW120 / STW120P users
You must have a minimum of 30cms from the end of the blast tube for the flame length otherwise you will get blow back into the burner which will keep cutting out.
If your boiler dose not have the depth to accommodate the flame length a smaller nozzle may be fitted. See Spares.
However due to the mishandling of the shipment by the carriers , i.e knocks and bumps sometimes problems may occur.
The following is the starting sequence:
The following may be helpful not only to the newly purchased burner but to Bairan burners already in service :
All Bairan burners are fully tested before dispatch.
If the Air pressure is showing low on the gauge i.e less than 0.4 kgs /cm sq or 5 psi check that the end cap allen bolts are tight and all air connections are properly connected. and there are no air leaks. Check round the end cap if possible with soapy water which will show up any leaks.
If the burner motor runs but makes no attempt to light and goes to reset after about 11 secs make sure the blast tube is in darkness otherwise the Photo Cell / Magic eye will detect that the burner is already lit and pass a message to the control box of a fault. This usually occurs when trying the burner on the bench and not in the boiler or cabinet. Check that you can hear the solenoid open after the 11 secs , if not check the solenoid connections in the plug.
The following applies to Bairan burners which have been removed and thoroughly cleaned and then will not light.
It is a good practice to run your burner every month on approx 4 litres of Kerosene. This keeps the nozzle holder and nozzle clean.
WARNING : Reduce the Temperature to Zero when running on Kerosene
Ensure that the Brake plate sits proud of the blast tube by approx 2 mm and the fan air vent is adjusted to the application , usually open 10mm
We have been working on these Bairan burners since 2003 so even though you did not buy your burner from us please call 07779017975 if you are having problems.
Here are some common Q&As
It is important that the oil level in the oil heater tank is below the level of the nozzle otherwise oil can bleed through the nozzle into the blast tube.
How to Get Better Pressure From Your Compressor
Remove the end cap, then remove the 6 Allen screws holding the compressor face plate. This will expose the rotor inside the compressor ring. Loosen, do not remove, the 2 Allen screws holding the compressor ring in place, then press the compressor ring tight against the rotor whilst tightening the 2 Allen screws. Ensure that all rotate. Then assemble everything again and you should have a better pressure.
If not a new rotor may be required.
