Y90 Series Inlet Fittings are used with Intermittent Pilot Ignition (IPI) and Standing Pilot Ignition (SPI) systems. Various pilot burner configurations, inlets, and flame sensors are available.
The Y90 Series inlet fittings control the flow of gas to a pilot burner and are designed to be used with BASO pilot burners. The majority of BASO inlet fittings have two holes which control and direct the flow of gas to the burner. The gas flow from the two holes intersects. This unique feature causes turbulence and a better gas/air mixture for proper combustion.
