Fuel Nozzle 60° B 1.5 GPH

Precision fuel atomizing nozzle for the burner, 60° spray angle, 1.5 gallons/hour (US GPH) flow rate. A critical component for correct heating output and combustion quality.

Application

The nozzle atomizes fuel in the burner's combustion chamber as a 60° cone, mixing it with combustion air. The 1.5 gph flow rate corresponds to the heating output designed for the specific unit variant – too low or too high a flow rate disrupts the fuel-air ratio and degrades combustion quality.

Symptoms – when to replace

• Unstable flame, smoking, or uneven combustion visible through the combustion chamber sight glass.
• Drop in outlet water temperature despite a sound burner and correct fuel pressure.
• Clogged or partially blocked nozzle causing an uneven fuel spray pattern.
• Soot deposits or uneven wear visible on the nozzle when disassembled.

How to choose the right part

Selection is based on reference number 44077 and the exact model variant – this number fits exclusively the therm CA 15/120 and therm-RP 1000. The CA 11/130, CA 12/150 and therm-RP 1200/1400/1600 models require different nozzle flow rates (different catalog numbers), despite belonging to the same equipment family.

Before ordering, be sure to confirm the exact model and heating output variant on the unit's nameplate – swapping the nozzle flow rate without the appropriate technical knowledge can affect combustion safety and efficiency.

What does the "60° B" designation on this nozzle mean?|60° is the fuel spray cone angle, and "B" is the spray pattern type (full cone) in the standard burner nozzle classification – both parameters, together with the GPH flow rate, determine the combustion characteristics.

Can I fit a nozzle with a different flow rate if I happen to have one on hand, instead of waiting for the correct 1.5 gph?|This isn't recommended without consultation – a different flow rate changes the heating output and fuel-air ratio, which can lead to incomplete combustion, smoking, or overheating of combustion chamber components.
