Front Glass Enclosure Panel, Removal and Installation
WARNING: Do not operate ap- pliance with the glass front removed, cracked or broken. Replacement of the glass should be done by a licensed or qualified service technician.
These are direct-vent appliances. They are designed to operate only when the front glass enclosure panel is installed. Generally the front glass enclosure panel should not be removed ex- cept to gain access to the components within the firebox, and the appliance may only be operated without the front glass enclosure panel in place for very brief periods of time during appliance checkout and adjustment. Be sure that the flame appearance will be diminished while the front glass enclosure panel is removed.

Warning: No not attempt to sub- stitute the materials used on this door, or replace cracked or broken glass with any materials other than those provided by the appliance manufacturer.
The glass door of this appli- ance must only be replaced as a complete unit as provided by the manufacturer. Do not attempt to replace broken, cracked or chipped glass separately.
Refer to Figure 4 and remove the front glass enclosure panel as follows:
1.Remove the bottom compartment door by lifting and pulling it towards the front of the fireplace.
2.Locate the two (2) latches at the top of the control compartment and disengage them from the floor frame bottom Vee-flange, pulling down on their handles to open them.
3.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.Retrieve the glass door frame. Visually inspect the gasket on the backside of the panel. The gasket surface must be clean, free of ir- regularities and seated firmly.
2.Position the door frame in front of the firebox opening and engage the top flange over the lip at the top of the firebox opening.
3.Swing the door down and back. Ensure the gasketseatsevenlyasthedoordrawsshut. Engage the Vee-flange at the bottom of the door with the latches and close the latches to secure the door.

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.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
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 sur- faces 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.
If the logs are properly positioned and sooting conditions exist, the air shutter opening on the main burner tube should be adjusted. Normally, themoreoffsetsintheventsystem,thegreaterthe need for the air shutter to be opened further.
Warning: Air Shutter Adjustment should only be performed by a qualified professional service technician.
Ensure that the front glass panel is in place and sealed during adjustment.
Burner Adjustment
Caution: The adjustment arm and nearby appliance surfaces are hot. Exercise caution to avoid injury while adjusting flame appearance.
To adjust the flame, move the adjustment arm (located in the lower control area) up or down to increase or reduce the air shutter opening, respectively. Position the air shutter to the factory setting as shown in Figure 5 on page 7. Allow the burner to operate for at least 15 minutes. Observe the flame continuously. If it appears weak or sooty as previously described, adjust the air shutter by pushing or pulling on the adjustment rod until the flame appearance is as desired.
The adjustment rod, arm and associated adjust- able 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 30 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 door.
