OUTDOOR BARRIER INSTALLATION INSTRUCTIONS
NOTE: This procedure requires two people.
Step 1. If the fireplace is on, turn it OFF. Allow it to cool completely.
BEFORE CONTINUING, FIREPLACE MUST BE OFF AND
COLD!
Step 2. Remove the two existing screws from the top of the Front
Glass Panel.
NOTE: After removing screws, one person must hold the
glass panel in place (to prevent it from falling forward and
breaking), while another person completes the installation.
Step 3. Insert the back lip of each Mounting Bracket (without the
hole) under the bottom edge of the Glass Panel.
Step 4. Attach one Spring Nut Clip (with straight edge facing front
and down) to the front lip of each Mounting Bracket, and
then align the holes.
Step 5. Slide the openings in the bottom edge of the Safety Guard
over the Spring Nut Clips.
Step 6. Align the holes in the top of the Outdoor Barrier with the
holes in the top of the Front Glass Panel. Use a Phillips
screwdriver to replace the two screws previously removed.
Align the holes in the lower front of the Ouddoor Barrier
with the holes in the Clips and Brackets. Use a Phillips
screwdriver to install the two supplied Washer Screws.
