Why Weishaupt WM-L20/2-A R Burner oil pump makes severe mechanical noise?
If the oil pump in your Weishaupt Burner is making severe mechanical noise, it might be sucking air, so ensure the oil supply is tight. Another possibility is that the suction resistance in the oil line is too high, so clean the filter and check the oil supply.
Why Weishaupt WM-L20/2-A R has no flame formation despite ignition and fuel?
If your Weishaupt Burner isn't forming a flame despite ignition and fuel, the ignition electrode might be set incorrectly, so set the ignition electrode correctly. Another reason might be that the mixing pressure is too high, so correct the mixing pressure in ignition load setting, if necessary adjust mixing head.
Why Weishaupt WM-L20/2-A R oil nozzle atomisation uneven?
Uneven oil nozzle atomization in your Weishaupt Burner is likely due to a soiled or worn nozzle, so replace the nozzle.
Why Weishaupt Burner has no oil throughput at the nozzle?
If there's no oil throughput at the nozzle of your Weishaupt Burner, it's likely because the nozzle is blocked, so replace the nozzle.
Why Weishaupt WM-L20/2-A R Burner fuel valve does not close tight?
If the fuel valve on your Weishaupt Burner isn't closing tightly, it's probably due to dirt particles in the fuel valve, so replace the fuel valve.
Why Weishaupt WM-L20/2-A R has heavy material erosion on the flame tube?
Heavy material erosion on the flame tube of your Weishaupt Burner may be caused by high boiler room temperatures or acidic combustion air due to ambient conditions, so use a H1 flame tube with higher temperature resistance.
