Delavan 01100-70b7 Oil Burner Nozzle 11 Gph 70 Degree

Product Description

The DELAVAN 01100-70b7 is a solid-cone Type B oil burner nozzle rated at 11 GPH flow rate with a 70-degree spray angle. It is designed to atomize fuel oil into a uniform droplet pattern throughout the full cone, supporting smooth ignition and efficient combustion in residential oil-fired heating systems. The brass body and steel orifice disc construction provide durability at the burner head, and a built-in Monel strainer helps protect the orifice from particulate contamination. Licensed HVAC technicians and oil burner service professionals install this nozzle as part of routine annual maintenance or combustion tune-up service.

The 01100-70b7 is suited for residential oil-fired burner applications where a solid-cone spray pattern is specified. The Type B solid-cone pattern distributes droplets fairly uniformly across the complete spray pattern at rated flow. Note that at flow rates above 8 GPH, the pattern becomes progressively more hollow, which is a known characteristic of solid-cone Type B nozzle design. This nozzle is appropriate for larger residential burners where a 70-degree angle and 11 GPH delivery rate match the combustion chamber geometry and burner head specifications.

Key Features

• Solid-cone Type B spray pattern for uniform droplet distribution throughout the full cone
• 11 GPH flow rate at 100 psi operating pressure
• 70-degree spray angle for compatibility with matched combustion chamber geometries
• Brass body with steel orifice disc for heat and wear resistance at the burner head
• Monel strainer filters particulates before they reach the orifice
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a solid-cone Type B nozzle with an 11 GPH flow rate and 70-degree spray angle at 100 psi.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut down the burner and allow the system to cool before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrodes during removal and installation. After installation, verify combustion quality with a flue gas analyzer before returning the system to service.
