MAINTENANCE

Turn off the gas and electrical power before servicing the fireplace.

CAUTION: Label all wires prior to disconnection when serv- icing controls. Wiring errors can cause improper and dan- gerous operation. Verify proper operation after servicing. This fireplace and its venting system should be inspected before use and at least annually by a qualified service per- son. The fireplace area must be kept clear and free of com- bustible materials, gasoline or other flammable vapours and liquids. The flow 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 shutter opening and the area surrounding the logs clean by vacu- uming 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 burn- ing properly.

4.Check to see that the pilot flame is large enough to engulf the thermocouple and thermopile and reaches to- ward 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 / dis- tributor.

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

Closing the air shutter will cause a more yellow flame, but can lead to carboning. Opening the air shutter will cause a more blue flame, but can cause flame lifting from the burner ports. The flame may not appear yellow immediately; al- low 15 to 30 minutes for the final flame colour to be estab- lished.

To access the air shutter, remove the two screws that se- cure the cover to the air housing, taking care not to dam- age the gasket.
