Delavan 1.20-70-W Oil Burner Nozzle 1.20 Gph 70 Degree

Product Description

The DELAVAN 1.20-70-W is a Type W all-purpose oil burner nozzle rated at 1.20 GPH flow rate with a 70-degree spray angle and a 100 psi operating pressure. It is identified by a green vial for quick field identification. This nozzle fits into residential and light commercial oil-fired heating systems and is installed by licensed oil burner technicians during seasonal tune-ups, nozzle replacements, or combustion efficiency services. The Type W designation means the spray pattern is neither truly hollow nor truly solid cone, giving it broad versatility across a range of burner configurations.

The 1.20-70-W is suited for oil burner applications where a flexible spray pattern is required. Type W all-purpose nozzles can be used in place of either solid or hollow cone nozzles across a flow range of 0.40 to 8.00 GPH, regardless of the burner air pattern. At lower flow rates, the spray pattern tends toward a more solid cone profile, making this nozzle adaptable to varying combustion head designs in residential forced-air furnaces, boilers, and water heaters fired on No. 2 fuel oil.

Key Features

• 1.20 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle for wide combustion coverage
• Type W all-purpose pattern — usable in place of solid or hollow cone nozzles from 0.40 to 8.00 GPH
• Green vial for fast visual identification in the field
• Lower flow rates produce a more solid spray pattern, adding versatility across burner air patterns

Compatibility

Designed as an OEM-style replacement nozzle for residential and light commercial oil burner systems requiring a Type W all-purpose spray pattern at 1.20 GPH and 70 degrees.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians. Shut off power to the burner and close the fuel supply valve before servicing. Use a proper nozzle wrench to remove and install the nozzle without stressing the electrode assembly or nozzle adapter. After installation, verify combustion performance with a flue gas analyzer before returning the system to service.
