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 servic- ing. This heater should be inspected and serviced before use and at least annually by a qualified service person. The fireplace area must be kept clear and free of combus- tible 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 oxygen deple- tion sensor system, remove the logs to expose both as- semblies.

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 burning properly.

4.Check to see that the pilot flame is large enough to engulf the thermocouple and thermopile and promptly ig- nites the main burner.

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.If using an optional catalytic door, check that the gasketing on the sides, and top of the door is not broken or missing. Replace if necessary.

CATALYTIC TILE MAINTENANCE

The catalytic tile is not field serviceable. It may only be handled or replaced by a qualified service person familiar with the specific characteristics of the appliance. Both room values and output from the catalytic tiles must be checked.

Check the room value with the heater off. Check the fire- place value after 10 minutes of heater operation to allow the tiles to come up to temperature.

In both cases the value of CO should not exceed 9ppm.

Catalytic output must be checked annually at the

beginning of the heating season.

CLEANING

This procedure must be performed by a qualified

service person!

Inspect the pilot for any visible contamination or debris (usually lint, pet hair, spider webs, carpet fibre, etc.) and remove.

Disconnect the pilot from the pilot tubing line. Using a 7/16” wrench, remove the injector from the pilot housing. Blow out the housing in the same direction as the gas flow.

Re-install the injector and the pilot tube, turn on the gas and check for leaks.

If this does not improve the performance, replace the pilot with an exact replacement. The device is tamper resist- ant with no field serviceable parts.

VENTURI ADJUSTMENT

Air shutter adjustment must only be done by a

qualified gas installer!

Closing the air shutter will cause a more yellow flame, but can lead to carboning.

WARNING: Carbon can be distributed in surrounding living area if the air shutter is improperly adjusted.

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; allow 15 to 30 min- utes for the final flame colour to be established.

Opening the air shutter will also reduce exhaust odours smelled within the room. See Trouble Shooting Guide.
