WARNING: DO NOT ATTEMPT TO SUBSTI- TUTE THE MATERIALS USED ON THESE DOORS, OR REPLACE CRACKED OR BRO- KEN GLASS WITH ANY MATERIALS OTHER THAN THOSE PROVIDED BY THE APPLI- ANCE MANUFACTURER.

THE GLASS DOORS 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 6 and remove the front glass enclosure panel as follows:

1.Remove the top bustle, and the top louver assembly or radiant panel. Then remove the bottom bustle.

2.Open the control compartment access panel. To open the control compartment access panel, actuate the spring-loaded magnetic catches securing the panel, by gently depressing the outer top corners of the panel until the catches "pop" the door free, allowing it to swing out and down to open.

3.Remove the bottom control compartment access panel by compressing the spring-loaded hinge pin on the left side until it disengages from the left cabinet corner post hole. Pull the panel away from the fireplace.

4.Once the control compartment access panel has been removed, the modesty panel can be removed as follows: pull the bottom right corner of the modesty panel out slightly to disengage the snap-fit feature; lift the modesty panel by the tab on the panel's right end, pull the right end of the panel away from the cabinet and then pull the panel diagonally out of the left side cabinet panel slots. (In the above procedure, reverse the words "left" and "right" for EBCR-2 models).

Remove the modesty panel carefully, so that none of the wires become loose or discon- nected. Now complete access to the gas control valve and its related controls is attainable.

6.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 latch and then close the latch to secure the panel.

4.Reinstall the modesty panel by inserting the tongues on the left side of it into the slots on the left side cabinet panel. Swing the right side of the modesty panel towards the unit. Engage the hook on the right side of the modesty panel with the right side cabinet panel slot. Gently press the bottom right corner of the modesty panel to engage the snap-fit feature.
