| ||
| • 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. |
Flame height adjustment will not work/works backwards
•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).
•Verify the selector switch on the battery pack is set to DC MOTOR DRIVE or LATCHING SOLENOID, depending upon which device is installed.
•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.
