Delavan 150-70b1 Oil Burner Nozzle 1.50 Gph 70 Degree Type B

Product Description

The DELAVAN 150-70b1 is a solid cone oil burner nozzle rated at 1.50 gallons per hour (GPH) and 100 psi, designed for precise fuel atomization in oil-fired heating systems. It produces a 70-degree Type B solid cone spray pattern, which promotes even fuel distribution and stable flame formation at the burner head. The body is brass with stainless-steel metering components, a bi-metal construction that holds tight machining tolerances and resists fouling over extended service cycles. Licensed oil burner technicians and HVAC service professionals install this nozzle as part of routine burner maintenance or tune-up service.

This nozzle is rated for residential oil-fired heating applications. It is suited for forced-air oil furnaces, oil boilers, and similar residential heating equipment where a 70-degree solid cone pattern at 100 psi is specified. The Type B spray classification indicates a wider, more evenly distributed cone profile, making it appropriate for burner heads that require solid-cone atomization at standard residential firing rates. Always verify the burner manufacturer's nozzle specification before installation.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner technicians or qualified HVAC service professionals. Shut off the burner and allow the system to cool before removing the nozzle assembly. Use an appropriate nozzle wrench to avoid damaging the nozzle adapter or electrodes. Follow all applicable local codes and the burner manufacturer's service instructions when setting electrode gap and air band adjustments after nozzle replacement.
