Questions and answers

What people ask about this product, answered by our pool techs.

What is the difference between H250FDN and W3H250FDN?
The sales channel and the warranty, not the heater. W3H250FDN is the Open Line number, which Hayward approves for sale online and in stores. H250FDN is the Expert Line number for the same size and fuel, sold through stores and pool professionals. This listing is W3H250FDN.
What does the IF code mean on a Hayward H250FDN?
Ignition failure. Hayward's guide says the heater tries three times, locks out, waits 60 minutes and tries three more. Our pool heater error code guide covers IF and the other codes.
What altitude can the Hayward H250FDN be installed at?
Up to 5,400 ft on natural gas with no modification, by Hayward's manual. The parts to take it to 7,700 ft outdoors come with the heater, and Hayward sells a kit for installations up to 10,100 ft.
What warranty does Hayward give the W3H250FDN?
One year on parts, with no labor coverage. That is Hayward's warranty for its Open Line, the W3 part numbers it approves for sale online. Hayward's longer parts and labor warranties belong to its Expert Line numbers, which it sells only through stores and pool professionals.
Where is the manual for the Hayward H250FDN?
Under Downloads on this page, as the Installation Manual. It is Hayward's Universal H-Series installation manual, and covers the H150FD through H500FD heaters in natural gas and propane.
Can the Hayward H250FDN be converted to propane?
Hayward's manual allows it with the conversion kit available from the factory, fitted only by a qualified service agency. Hayward also sells the propane heater ready built, as the W3H250FDP.
