MAINTENANCE

TURN OFF THE GAS AND ELECTRICAL POWER

BEFORE SERVICING THE FIREPLACE. CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after ser- vicing. 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 fl ammable vapours and liquids. The fl ow of combustion and ventilation 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 shut- ter opening and the area surrounding the logs clean by vacuuming or brushing, 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 light-up period is satisfactory. If ignition takes longer, consult your NAPOLEON® dealer / distributor.

7.Check that the gasket on the sides, top and bottom of the door is not broken or missing. Replace if necessary.
