In oil burners, which parameter should be checked?

• A. Manifold temperature
• B. Gas supply rate
• C. Vent piping condition
• D. Oil pressure

Answer: (D)

Oil burners need a steady, correct fuel pressure to atomize the oil into a fine spray and deliver it into the combustion chamber. The pump must maintain this pressure so the nozzle can create the proper spray pattern for stable flame and efficient combustion. If the pressure is too low, atomization is poor, the flame can be weak or extinguish, and smoke or soot can increase. If it’s too high, it can cause over-atomization, poor combustion, and added wear on the nozzle. Therefore, checking oil pressure with a gauge on the service valve and ensuring it matches the nozzle and burner manufacturer’s spec is essential. The other items aren’t the primary parameter to verify for an oil burner: manifold temperature is more a concern with gas burners, vent piping condition relates to safe venting rather than a controllable operating parameter, and gas supply rate is specific to gas-fired systems rather than oil burners.
