Product details
Pentair 460745 is the air orifice kit for the model 250 BTU pool heater. It is the genuine Pentair part.
Why the size matters
Orifices meter the flow into the burner, and the sizing is specific to the heater it was designed for. Fitting a kit intended for a different BTU rating changes the mixture, so the first step is confirming that the heater on the pad is the 250.
When it is fitted
This is a burner service part rather than routine maintenance. It goes in when the orifices are being renewed as part of work on the burner assembly.
