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 danger- ous operation. Verify proper operation after servicing. This

fireplace and its venting system should be inspected before use and at least annually by a qualifi ed service person. The

fireplace 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 ob- structed.

1.In order to properly clean the burner and pilot as- sembly, remove the bowl and rockset to expose both assemblies.

2.Keep the control compartment, bowl and rockset, burner, air shutter 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 bowl and rockset.

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 gasketing on the sides, top and bot- tom of the door is not broken or missing. Replace if necessary.

PILOT BURNER ADJUSTMENT

Adjust the pilot screw to provide properly sized fl ame. Turn in a clockwise direction to reduce the gas fl ow.

Check Pressure Readings: (Fig. 60)

Inlet pressure can be checked by turning screw (A) coun- ter-clockwise 2 or 3 turns and then placing pressure gauge tubing over the test point. Gauge should read 7” (minimum 4.5”) water column for natural gas or 13” (11” minimum) water column for propane. Check that main burner is operating on “HI”.

Outlet pressure can be checked the same as above using screw (B). Gauge should read 3.5” water column for natural gas or 10” water column for propane. Check that main burner is operating on “HI”.

AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS CLOCKWISE FIRMLY TO RESEAL. DO NOT OVERTORQUE.

Leak test with a soap and water solution.
