Troubleshooting American Flame Gas Control System (continued)

Main ﬂame will not light	• 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.
	• 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. 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	• Ensure the black and red leads from the battery pack or the AF4000 110H/L module

	ing solenoid located on the valve body (red to red and black to black).
	• Make sure the Pulse/Continuous button on the Power Module is set to Continuous
	mode. If ﬂame does not continuously change (increase or decrease in size) while
	holding down the ON H/L button, the power module mode must be changed. Hold
	down the Pulse/Continuous button on the Power Module for 10 to 15 seconds to
	change mode from pulse to continuous. Re-try ﬂame adjustment.
	• 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 in-
	stalled 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.

Unit will not respond in THERMO mode.

(When using thermostatic transmitters only)

•Ensure the thermostatic transmitter is within the 20’ operational range.

•Make sure an ON or OFF command was not last sent from another transmitter. These commands will override the thermal commands from the handheld transmit- ter. To return the system to THERMO mode, press either ON or OFF on the ther- mostatic transmitter, then press the MODE button to put the system in THERMO mode. Press and hold the SET button to change the set temperature.

•Verify the set temperature on the thermostatic remote is at least 2 degrees above or below the room temperature. The system will not react to temperatures within 2 degrees of the set temperature.
