A pilot assembly for a furnace burner includes a housing having a first port capable of mating with a flame detector which can monitor the pilot or main flame of the furnace burner. The housing further includes an air-fuel mixture inlet port coaxially disposed with respect to a second port, which serves the purpose of mating with a spark ignition means. The axes of the fuel mixture inlet port and second port are substantially perpendicular to the axis of the first port. The second port is adapted such that any portion of the spark ignition means extending through the second port and into the housing will not interfere with the monitoring performed by the flame detector means. The housing further includes a third port which can accommodate means for visually sighting the pilot flame. The third port can also serve the purpose of providing manual ignition of the pilot burner.
