Atmospheric Vent - White Rodgers Electronic
CQSG-AV-WR-05

Operation Overview
This White Rodgers Electronic Gas Valve is powered by millivolt (mV) output, from a thermopile heated by the standing pilot flame. No external
power or battery is required to run the control. During normal operation the LED status indicator will flash once every second on a call for heat.
When the setpoint knob is turned to pilot, or the control is in standby, the LED will flash once every four seconds.
Be sure the water heater is full of water before lighting the pilot.
Measuring Thermopile Output
Piezo Igniter
Green LED
Indicator
Thermopile Wire Connections
Using a voltmeter, touch each lead to the wires plugged into the front of
the control; if necessary fold open the tabs to expose the connections.
Typical readings are as follows:
When the pilot is lit voltage will steadily climb to approximately 300-
500 mV.
Immediately after the LED blinks, the voltage will drop approximately
100-150 mV then stabilize. This is normal operation.
Pilot Lighting Checklist
WARNING: Read ALL safety information on the
operating instruction label of the water heater
before proceeding. Smell for gas around the
heater, including near the floor. If you smell gas,
follow the safety information on the label.
Press and hold the setpoint knob in.
Click the piezo igniter up to ten times, rapidly.
With the pilot lit, hold the setpoint knob in,
until the LED blinks—this can take up to 90
seconds.
Increase pressure on the knob to ensure the
pilot valve engages.
Wait until the third LED blink before releasing
the knob.
Turn the setpoint knob to the desired
temperature setting. The recommended
setting is the “Hot” position, approximately
120°. The LED will blink once every second to
indicate a call for heat.
Release the knob if there is no blink after
90 seconds. Wait five minutes before
trying to relight.
On the first heat cycle, the control waits
several seconds to light the burner. This is
normal operation.
