L.B. White Pilot Light Ignition Installation And Service Manual page 75

The preceding instructions dealing with inlet and manifold
pressure checks and leak testing generally apply to all
control valves. However, due to model and age variations of
heaters, there are several differences between control
valves with which you must be familiar.
Part number 500-02309 has burner manifold pressure
taps located on either side of the control valve's main
solenoid.
The inlet pressure tap is located near the pilot button
and pilot line connection.
This control valve does not incorporate an internal gas
shut off nor low pressure regulator.
adjustments must be made at the second-stage
regulator supplying gas to the heater. Additionally, the
gas supply will need to be shut off at the supply line to
isolate the heater.
