Remove the top louver assembly by gently lifting it upward until the hook catches on boths sides clear the locating slots. Then pull door out to remove. 2. Removethecontrolcompartmentaccessdoor the same way as described in Step 1 above. 3. Locate the two (2) latches at the top of the control compartment. To disengage the two latches from the bottom vee-flange of the glass enclosure panel, reach for the handles located towards the back of the latches and pull the handles down toward the front of the appliance. 4. Swing the bottom of the door out and raise it slightly to lift the top flange of the door frame away from the appliance. Installing Glass Enclosure Panels (see Figure 57) 1.Visuallyinspectthegasketonthebacksideofthe glass panel. The gasket surface must be clean, free of irregularities and seated firmly. 2. Position the glass enclosure panel in front of the firebox opening at a 45 degree angle and engage the top flange over the lip at the top of the firebox opening. See Figure 57. 3. Swing the glass enclosure panel down and back. Ensure the gasket seats evenly as the panel draws shut. Engage the Vee-flange at the bottom of the panel with the latches and close the latches to secure the panel. 4.

BURNER ADJUSTMENTS Flame Appearance and sooting Proper flame appearance is a flame which is blue at the base and becomes yellowish-orange in the body of the flame. When the appliance is first lit, the entire flame may be blue and will gradually turn yellowish-orange during the first 15 minutes of operation. If after a short period the flame stays lowered blue, or if the flame is orange with evidence of sooting (black tip), the air shutter opening may need to be adjusted.

Sootingresults inblackdepositsformingonthe logs, appliance inside surfaces and on exterior surfacesadjacenttotheventtermination. Sooting is caused by incomplete combustion in the flames and lack of combustion air entering the air shutter opening. To achieve a warm yellowish- orange flame with anorange body that does not soot, the shutter opening must be adjusted between these two extremes. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. Air Shutter Adjustment Guidelines • Ifthereissmokeorsootpresent,firstcheck the log set positioning to ensure that the flamesare not impingingonany ofthelogs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased. • Themoreoffsetsintheventsystem,thelarger the air shutter opening will need to be. • An appliance operated with the air shutter openedtoofar,mayhaveflamesthatappear blueandtransparent. Theseweak,blueand transparent flames are termed anemic. • Propane models may exhibit flames which candle or appear stringy. If this is present and persists,adjusttheair shuttertoamore closed position, then operate the appliance for a few more minutes to ensure that the flame normalizes and the flames do not appear sooty. The following chart is provided to aid you in achieving the correct air shutter adjustment for your installation.

Burner Air Shutter Adjustment Procedure CAUTION Theairshutterdoorandnearbyappliancesurfacesare hot. Exercise caution to avoid injury while adjusting flame appearance. Burner Air Shutter Adjustment Procedure 1. Locate adjustment rod and adjust air shutter to the standard setting as shown in Figure 60 (adjustment rod is located in the lower control compartment). Note: Move the adjustment rod down to decreases air and up to increases. 2. Light appliance (follow lighting procedure on lighting label in control compartment or see homeowners manual). 3. Allow the burner to operate for at least 15 minutes while observing the flame continuously to ensure that the proper flame appearance has been achieved (see Figure 57 or 58). If the following conditions are present, adjust accordingly. • If flame appears weak or sooty, adjust the air shutter, incrementally, to a more open position until the proper flame appearance is ...
