Oilon is a Finnish manufacturer of burners and heating and cooling systems. In the U.S., its burners are mostly found on larger boilers and process equipment, including industrial and low-NOx models.
Like most modern industrial burners, Oilon burners are usually set up on an electronic fuel-air ratio control, often with O2 trim. On those systems, the base fuel-air curve still has to be set correctly first, since trim only makes small corrections around it.
What we check on every startup or tune-up: fuel pressures against the burner's specification, the safety switches and limits, ignition and the flame signal, and the fuel-air ratio at each firing rate, measured with a calibrated combustion analyzer. You get the O2, CO, and efficiency readings before and after, in writing.
Common reasons to call: lockouts or flame failures that keep coming back, hard starts, high CO or soot, a burner that hasn't been tuned in over a year, or a burner coming back online after repairs, a fuel change, or a control replacement.
