Product details
The Hayward IDXLFHA1930 is the genuine front header assembly for Hayward Low NOx pool heaters. It is the front water end of the heat exchanger, supplied as a complete assembly.
What the header does
Water leaves the plumbing, enters the header and is distributed into the heat exchanger tubes where it picks up heat. Because it handles the water directly, the header carries the full effect of pool chemistry. Low pH, high sanitizer levels and restricted flow all attack it, and the usual symptom is a leak at the front of the heater or visible corrosion around the casting.
Before you order
The source lists this part by number and by the Low NOx range rather than by a specific model list, and Hayward supplies the rear header separately. Confirm IDXLFHA1930 against the parts breakdown for your heater, and check the front against the rear position, before ordering.
