2.Adjust the pilot screw to provide properly sized pilot flame (Figure 30 ). Turn counter clockwise to enlarge pilot flame and clockwise to reduce the pilot flame. DO NOT attempt to adjust pilot flame more than one half turn.

3.Replace the pilot adjustment cap. Replace logs if removed for pilot inspection.

To light the burner; rotate the gas valve control knob counterclockwise to the “ON” positionand then turn “ON” the remote wall switch.

The gas control system on these appliances is an electronic low voltage gas control valve with an intermittent ignitor. It consists of a low voltage gas control valve, an intermittent igni- tion system, an electronic control module, transformer and a burner assembly. A tem- perature limit switch is wired in series with the gas control valve. If a higher than normal temperature is sensed, due to a blocked vent or prolonged downdraft, the limit switch will open and cause the burner to shut off.

The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge.

To light the burner, push the gas control lever in and toward the left to the “ON” position. Turn ‘ON’ the remote wall switch. Ensure the ignitor lights the pilot. The pilot flame should engulf the ignitor.

Step 11. Safety Limit Switch Operation

MANUALLY-RESET BLOCKED FLUE SAFETY SWITCH

These appliances are equipped with a manu- ally-reset blocked flue safety switch. Refer to Figures 31 and 32 for their location. If during appliance operation, the flame goes out (independently of the burner on/off wall switch), it may be due to the operation of the safety limit switch. First allow the appliance to cool. Then reset the safety switch by pushing the red reset button on the back of the switch.

CAUTION: THE ELECTRONIC APPLIANCE SHOULD BE TURNED OFF BEFORE REMOV- ING THE LIMIT SWITCH.
