Description

Precision fuel atomizing nozzle for the burner, 60° spray angle, 1.65 gallons/hour (US GPH) flow rate. A higher-flow variant than the standard 1.5 gph nozzle, matched to models with higher heating output.

Application

The nozzle atomizes fuel in the burner's combustion chamber as a 60° cone, mixing it with combustion air. The higher 1.65 gph flow rate corresponds to the greater heating output of the therm 10-17 and therm-RP 1200-1600 models compared with the smaller variants in the same equipment family.

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 440773 and the exact model variant – this number fits the therm 10-17 and therm-RP 1200/1400/1600. Smaller models in the same family (therm 7-15, therm-RP 1000) require nozzles with a lower flow rate (different catalog numbers), despite belonging to the same product line.

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.
