Delavan 1.50-70-B Oil Burner Nozzle 1.5 Gph 70 Degree

Product Description

The DELAVAN 1.50-70-B is a solid cone oil burner nozzle rated at 1.5 gallons per hour (GPH) with a 70-degree spray angle and a 100 psi operating pressure. Designed for residential and light commercial oil-fired heating equipment, it atomizes fuel oil into a finely distributed droplet pattern for efficient combustion. The Type B solid cone configuration distributes droplets uniformly throughout the full spray pattern, promoting smooth ignition. This nozzle is installed by licensed oil burner technicians and HVAC service professionals during annual tune-ups, nozzle replacements, or combustion efficiency service calls.

The 1.50-70-B is suited for oil burners requiring a solid cone spray pattern at moderate-to-higher flow rates. Solid cone Type B nozzles are commonly specified in larger burner applications where uniform droplet distribution across the entire pattern improves combustion stability and reduces soot buildup. Note that at flow rates above 8.00 GPH, the spray pattern in Type B nozzles becomes progressively more hollow, so this nozzle is best applied within its rated flow range. The blue vial color coding identifies the spray angle for quick field identification during servicing.

Key Features

• 1.5 GPH flow rate at rated operating pressure
• 70-degree spray angle for wide pattern combustion coverage
• Solid cone Type B pattern distributes droplets uniformly throughout the full spray cone
• Rated for 100 psi operating pressure
• Blue vial color coding for fast spray angle identification in the field
• Promotes smooth ignition and efficient combustion in larger oil burner applications

Compatibility

Designed as an OEM-style replacement nozzle for oil burner equipment requiring a 1.5 GPH, 70-degree solid cone Type B nozzle at 100 psi.

Installation Notes

Oil burner nozzle replacement should be performed by a qualified oil burner technician or licensed HVAC professional. Always shut down the burner and allow the system to cool before servicing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the nozzle body or electrode assembly. Following replacement, verify combustion performance with a flue gas analyzer to confirm proper air-fuel ratio and CO levels.
