•
Ensure the CONTINUOUS PILOT switch on the control module (Fig. 45) is set
to OFF.
•
Verify the gas supply is turned on.
•
Ensure the pilot flame will ignite. If not, see pilot flame troubleshooting above.
•
Make sure the green and white leads from the module are securely connected to
the terminals labeled “MAIN: on the valve body. (Fig. 48)
•
Make certain the pilot flame is in contact with the flame rectification sensor on
the pilot assembly. This valve is equipped with a pilot flame adjustment screw.
(Fig. 48) If the pilot flame is too small it will not contact the flame rectification
sensor and will not complete the safety circuit.
•
Ensure the pilot flame is properly located to ignite the main flame.
•
Ensure the black and red leads from the battery pack or the AF4000 110H/L
module are securely connected to the red and black leads from the motor drive
or H/L latching solenoid located on the valve body (red to red and black to
black).
•
Check functionality with all transmitters to determine if there is an issue with the
main control system or an individual transmitter. If the issue is with an individual
transmitter, make sure the batteries in both the transmitter and receiver are
installed in the proper direction and are not drained. Individual battery voltage
should be no less than 1.4V for AA and AAA batteries, 2.8V for button cells, and
9.0V for 12V batteries.
