Delavan 00175-70a1 Oil Burner Nozzle 1.75 Gph 70 Degree

Product Description

The DELAVAN 00175-70a1 is a Type A hollow cone oil burner nozzle rated at 1.75 gallons per hour (GPH) with a 70-degree spray angle. It atomizes fuel oil into a fine, hollow cone pattern that promotes efficient combustion in residential and light commercial oil-fired heating equipment. The hollow cone pattern distributes fuel along the outer edge of the spray envelope, supporting stable ignition and clean burn characteristics. This nozzle is installed by oil burner service technicians during routine maintenance or burner tune-ups and should be replaced on a scheduled basis to maintain combustion efficiency.

This nozzle is suited for oil-fired furnaces, boilers, and water heaters that require a Type A hollow cone spray pattern at a 1.75 GPH flow rate and a 70-degree angle. It is a common service item in residential heating systems burning No. 2 fuel oil. Technicians select nozzle type, flow rate, and angle based on burner manufacturer specifications and combustion analysis results. Always verify the replacement nozzle matches the original specifications listed on the burner data plate or service manual.

Key Features

• Type A hollow cone spray pattern for efficient fuel atomization along the outer spray envelope
• 1.75 GPH flow rate for precise fuel delivery matching burner design requirements
• 70-degree spray angle for compatibility with appropriate blast tube and combustion chamber geometry
• Lightweight at 0.12 pounds for easy single-handed installation
• Designed for routine seasonal replacement to maintain combustion efficiency and reduce sooting

Compatibility

Designed as an OEM-style replacement nozzle for oil-fired furnaces, boilers, and water heaters requiring a Type A hollow cone nozzle at 1.75 GPH and a 70-degree spray angle. Always confirm compatibility against the burner manufacturer specifications before installation.

Installation Notes

Oil burner nozzle replacement is performed by qualified oil burner technicians. Shut down the burner and allow the system to cool before servicing. Use a proper nozzle wrench to remove and install the nozzle without damaging the nozzle adapter or electrode assembly. After replacement, perform a combustion analysis to verify CO2, stack temperature, and smoke number are within acceptable limits per the burner manufacturer guidelines.
