pilot after		repeatedly					• If ignitor connections are good but no spark, replace
pressing the spark ignitor							ignitor.
				Broken spark electrode			• Check for broken ceramic insulation, replace electrode
							if broken.
				Misaligned spark electrode			• If spark is not arcing from electrode to pilot, adjust
							by loosening the screws on the pilot base. Adjust and
							tighten.
Pilot will not remain lit				Problem with thermocouple			• Check for proper connection of the thermocouple to
				circuit			the rear of the valve; if loose fully tighten.
							• Check pilot for full flame impingement around
							thermocouple. If flame is too small, check gas
							pressure, adjust pilot rate screw, check pilot head for
							damage.
							• Check thermocouple voltage at valve. It must be
							greater than 5mV. If low, replace thermocouple.
				Air in gas line (pilot dies			• Bleed line.
				while knob is depressed)			• Check gas line pressure.
							• Contact dealer.
Burners	will	not	remain	Problem	with thermopile		• Check gas line pressure .
lit				circuit			• Check for flame impingement in thermopile. If low,
							see “Pilot will not remain lit”.
							• Check thermopile for minimum of 300mV when
							burner is switched on.
							• Check wiring to thermostat for breaks.
Flame lifting				Leak in vent pipe			• Check for leaks in vent connections.
				Improper vent configuration			• Check vent configuration with manual.
				Terminal	may	be	• Check to see if terminal is on correctly.
				recirculating flue gases			• May need to install high wind termination cap.
							• Contact dealer.
Glass fogs up				Normal Condition: after the appliance warms up the glass will clear.
				**Due to additives in gas, glass may get hazy during operation** Clean as needed.
Blue Flames				Normal during start up: flames will yellow as the fireplace heats up.
Flames are burning “dirty”				Flame impingement			• Check log positioning.
or sooting							• Increase primary air by opening the venturi shutter
							and/or by opening the vent restrictor.
							See also “Burners will not stay lit”.
Remote	control		doesn’t	Problem with the remote			• One or more of the batteries are dead. See remote
work							control instructions.
				Problem with fireplace			• The on/off switch is turned to OFF.
							• The gas control valve is turned to PILOT or OFF.
							• The pilot has gone out.
