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. If the air shutter opening is closed too far, 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 lack of combustion air entering the air shutter opening. To achieve a warm yellowish-orange flame with an orange body that does not soot, the shutter opening must be adjusted between these two extremes. Air Shutter Adjustment Guidelines • If there is smoke or soot present, first check the log set positioning to ensure that the flames are not impinging on any of the logs. If the log set is properly positioned and a sooting condition still exists, then the air shutter opening should be increased. • The more offsets in the vent system, the larger the air shutter opening will need to be. • An appliance operated with the air shutter opened too far, may have flames that appear blue and transparent. These weak, blue and transparent flames are termed anemic. • Propane models may exhibit flames which candle or appear stringy. If this is present and persists, adjust the air shutter to a more 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. Figure 9 - Burner Flame Appearance Model SSDV-3328 Series Burner Air Shutter Adjustment Procedure 1. Locate adjustment rod and adjust air shutter to the standard setting as shown in Figure 10 (adjustment rod is located in the lower control compartment). Note: Rotating the adjustment rod counterclockwise increases air and clockwise decreases air. 2. Light appliance (follow lighting procedure on lighting label in control compartment or see pages 16 and 18). 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 9). 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 achieved. • If flame stays lowered blue, adjust the air shutter, incrementally, to a more closed position until the proper flame appearance is achieved. 4. Leave the control knob (off/pilot/on) in the ON position and the burner OFF/ON switch OFF (& remote switches, if applicable). 5. When satisfied that the burner flame appearance is normal, close the lower control compartment door. WARNING Air shutter adjustment should only be performed by a qualified professional service technician. WARNING Ensure front glass panel is in place and sealed during adjustment. CAUTION The air shutter door and nearby appliance surfaces are hot. Exercise caution to avoid injury while adjusting flame appearance. CAUTION Carbon will be produced if the air shutter is closed too much. Any damage due to carboning resulting from improperly setting the air shutter is not covered under the warranty. Air Shutter Adjustment Guidelines: Amount of Primary Air Flame Color Air Shutter Adjustment If air shutter is closed too far Flame will be orange Air shutter gap should be increased If air shutter is open too far Flame will be blue Air shutter gap should be decreased Electronic Appliance Checkout To light the burner, refer to the lighting instructions on Pages 18 & 19. Ensure the igniter lights the pilot. The pilot flame should engulf the flame sensor as shown in Figure 13.
