Switch off all electrical power, turn the "ON/OFF" switch to "OFF" and turn the gas control knob to "OFF." The pilot light should go out. Wait five minutes for any remaining gas to clear. Do not proceed if you smell gas. Let the fireplace cool if it was recently in use.
Pull the top louver, the vent above the glass, up and out. Carefully lean the glass panel forward; the hinged bottom louver swings with the glass.
Pull down on the clamp handles along the lower edge of the frame to release the glass panel in its frame.
Gently tilt the frame outward at the bottom and lift the glass panel and frame out of the fireplace. Reverse these steps to replace the glass panel when cleaning is complete.
