Product details

The Hayward FDXLBOP1930 is the liquid propane burner orifice kit for the Universal H-Series Low NOx heater in the FD range. The orifices are the small metered jets that meter gas into each burner, and their size is what matches the heater to the fuel it is burning.

What it fits

Hayward lists this kit for the Universal H-Series Low NOx heaters H150FD, H200FD, H250FD, H300FD, H350FD and H400FD, and for the ASME pool and spa heater versions of the same range. Check the model plate on your heater against that list before ordering.

Propane, not natural gas

Propane orifices are drilled smaller than natural gas orifices because propane carries more energy per unit of volume. Fitting the wrong set gives you either a starved flame or an overfired heater, so the gas type on the kit has to match the gas at the meter or the tank.

Who should install it

Orifice work sits inside the fuel train. Have a qualified gas technician fit the kit and verify manifold pressure and burner appearance afterward.

Questions and answers

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

Is this for natural gas or propane?
Liquid propane. The natural gas orifices are a different Hayward part, and the two are not interchangeable.
Which heaters does it fit?
Hayward Universal H-Series Low NOx heaters in the FD range: H150FD, H200FD, H250FD, H300FD, H350FD and H400FD, including the ASME pool and spa heater versions.
Can I fit it myself?
Changing burner orifices alters the gas train and the burn characteristics of the heater. Have it done by a qualified gas technician who can check the manifold pressure afterward.
Why would I need new orifices?
Either to convert the heater to liquid propane, or to replace orifices that have been damaged, blocked or lost during service.
