	• 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.
	• Does the remote show CP in the display? If yes, childproof is on. Refer to trans-
	mitter operating instructions in this manual.
	• Check continuity of main burner coil in gas valve. Remove wire connector. If there
	is no continuity, replace valve.

	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 2 to 3 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
	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.

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 trans- mitter. To return the system to THERMO mode, press either ON or OFF on the thermostatic transmitter, then press the MODE button to put the system in THER- MO 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.
