Product details
This is the Hayward FDXLBON1930 natural gas burner orifice kit for the Universal H-Series Low NOx heaters. It covers the FD model range, H150FD, H200FD, H250FD, H300FD, H350FD and H400FD.
What the orifices do
Each orifice is a precisely sized opening that meters gas into the burner. The size sets how much fuel reaches the flame, which is why orifices are matched to both the fuel type and the heater size. Damaged, corroded or previously drilled orifices upset that metering and show up as poor flame, sooting or a heater that will not hold its temperature rise.
Match the fuel
This is the natural gas kit. Hayward supplies a separate part for propane, so check the rating plate on the heater before ordering. Orifice replacement and any fuel conversion is work for a licensed gas technician, who can verify manifold pressure and combustion once the kit is fitted.
