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. To install the front glass enclosure panel, proceed as follows: 1. Visually inspect the gasket on the backside of the 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. 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. Reinstall the top louver assembly or radiant panel. Burner Adjustments The following paragraphs address burner adjustment concerns and procedures. Flame Appearance and Sooting Proper flame appearance is a matter of taste. Generally most people prefer the warm glow of a yellow to orange flame. Appliances operated with air shutter openings that are too large will exhibit flames that are blue and transparent. These weak, blue and transparent flames are termed anemic. If the air shutter opening is too small sooting may develop.Sooting is indicated by black puffs developing at the tips of very long orange flames. Sooting results in black deposits forming on the logs, appliance inside surfaces and on exterior surfaces adjacent to the vent termination. Sooting is caused by incomplete combustion in the flames and a lack of combustion air entering the air shutter opening. To achieve a warm yellow to orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes. No smoke or soot should be present. Reposition the log set if the flames impinge on any part of it. If the log set is properly positioned and sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Normally, the more offsets in the vent system, the greater the need for the air shutter to be opened further. ENSURE THAT ALL GLASS PANELS ARE IN PLACE AND SEALED DURING ADJUSTMENT. The adjustment rod and associated adjustable air shutter is patented technology. Flame adjustments can be made quickly and accurately to taste without the need of disassembling the appliance and waiting for 15 minutes after each adjustment. Propane models may exhibit a flame pattern that may candle or appear stringy. If this is problematic or persists as the appliance is continually operated, adjust the air shutter closed as described in the previous paragraphs. Operate the appliance for a period of time as the effect diminishes, ensuring that the appliance does not develop sooty flames. When satisfied that the appliance operates properly, proceed to finish the installation. Leave the control knob in “ON” position and turn the remote switch “OFF.” Close the lower control compartment access panel. Adjustment CAUTION: THE ADJUSTMENT ROD AND N...
