Monarch Oil nozzle 60.00GPH / 80PLP

The Monarch Oil nozzle 60.00GPH / 80PLP is a precision consumable part that atomizes fuel oil into a fine cone for complete and stable combustion. It has a capacity of 60 gallons per hour, a spray angle of 80 degrees, and a spray pattern designated as PLP. This nozzle is designed for use in oil burners to evenly distribute fuel and form an optimal mixture with air, ensuring efficient combustion. The designation 60.00GPH / 80PLP indicates its flow rate at the reference pressure, spray angle, and pattern code, which must match the burner data plate for proper operation.

When replacing a nozzle of this type, verify the existing part's marking and select a unit with the same GPH rating, spray angle, and pattern designation as specified on the burner data plate. The nozzle threads into the oil line and works with the oil pump and solenoid valve. Correct atomization depends on the pump pressure being set to the reference value used for the nozzle rating. Ensure all three parameters—flow rate, angle, and pattern—match to avoid sooting, pulsation, or ignition instability.

If a nozzle of this kind fails or is mismatched, the burner may exhibit sooting, pulsation, or ignition instability. These symptoms can result from incorrect flow rate, spray angle, or pattern, or from improper pump pressure. Check the nozzle's marking against the burner data plate and verify the pump pressure is set to the reference value.
