Closing the air shutter will cause a more yellow fl ame, but can lead to carboning. Opening the air shutter will cause a more blue fl ame, but can cause fl ame lifting from the burner ports. The fl ame may not appear yellow immediately; allow 15 to 30 minutes for the fi nal fl ame color to be established.

MAINTENANCE
Purge all gas lines with the glass door of the fireplace removed. Assure that a continuous gas flow is at the burner before installing the door.
TURN OFF THE GAS AND ELECTRICAL POWER BEFORE
SERVICING THE FIREPLACE.
CAUTION: Label all wires prior to disconnection when servic- ing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. This fi replace and its venting system should be inspected before use and at least annually by a qualifi ed service person. The fi replace area must be kept clear and free of combustible materials, gasoline or other
flammable vapors and liquids. The fl ow of combustion and ventila- tion air must not be obstructed.
1.In order to properly clean the burner and pilot assembly, remove the logs to expose both assemblies.
2.Keep the control compartment, logs, burner, air shutter opening and the area surrounding the logs clean by vacuuming or brush- ing, at least once a year.
3.Check to see that all burner ports are burning. Clean out any of the ports which may not be burning or are not burning properly.
4.Check to see that the pilot fl ame is large enough to engulf the thermocouple and thermopile and reaches toward the burner with the third jet.
5.Replace the cleaned logs.
6.Check to see that the main burner ignites completely on all openings when the gas knob for the burner is turned on. A 5 to 10 second total
7.Check that the gasket on the sides, top and bottom of the door is not broken or missing. Replace if necessary.
