Front Glass Enclosure Panel, Removal

and Installation.

WARNING: NEVEROPERATETHEAPPLIANCE WITHOUT THE GLASS ENCLOSURE PANEL IN PLACE AND SECURE. DO NOT OPERATE APPLIANCE WITH THE FRONT GLASS PANEL CRACKED, BROKEN OR MISSING. REPLACEMENT PANELS ARE AVAILABLE THROUGH YOUR LOCAL LENNOX DEALER AND MUST BE INSTALLED BY A LICENSED OR QUALIFIED SERVICE TECHNICIAN.

These are direct-vent appliances. They are designed to operate only with the front glass enclosure panel properly installed. Generally, the glass enclosure panel should not be removed except 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 initial appliance checkout and adjustment.

During this appliance checkout and adjustment period, a potential safety hazard exists - EXERCISE EXTREME CAUTION to prevent the occurrence of any burn injuries from the exposed flames or hot surfaces. Also note, that while the front glass enclosure panel is removed, the flame appearance will appear to be smaller than normal.

WARNING: HANDLE THE GLASS WITH EXTREME CARE! TEMPERED GLASS IS SUSCEPTIBLE TO DAMAGE (SCRATCHES, FOR EXAMPLE) – HANDLE GLASS DOOR (GLASS ENCLOSURE PANEL) GENTLY WHILE REINSTALLING IT.

WARNING: NO NOT ATTEMPT TO SUBSTITUTE 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 APPLIANCE 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 5 and remove the front glass enclosure panel as follows:

1.Remove the top louver assembly or radiant panel.

2.Open the hinged drop-down control compartment access panel.

3.Locate the two (2) latches at the top of the control compartment and disengage them from the door frame's bottom Vee-flange, pulling down on their handles to open them.

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 irregularities 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 gasket seats evenly as the door draws shut. Engage the Vee-flange at the bottom of the door with the latches and close the latches to secure the door.

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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 adjustedbetweenthesetwoextremes. Nosmoke or soot should be present. Reposition the logs if the flames impinge on any of them.

If the logs are 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.

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.

Adjustment

CAUTION: THE ADJUSTMENT ROD AND NEARBY APPLIANCE SURFACES ARE HOT. EXERCISE CAUTION TO AVOID INJURY WHILE ADJUSTING FLAME APPEARANCE.

To adjust the flame, move the adjustment rod (located in the lower control area) up or down to increase or reduce the air shutter opening, respectively. Initially, always position the air shutter to the factory setting (the minimum air opening position) as shown in Figure 6 on page 7. This can be done by pulling the adjustment rod all the way down. 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 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 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.
