007" diameter provides exact flow restriction for sensitive pneumatic pilot signals

the bulb should be mounted at the 4 or 8 o’clock position on a horizontal run

ensure the shaft diameter is between 3/8" to 1" for proper coupling

How do I verify if the flame signal is adequate via this electrode
