Before proceeding, make sure the gas control valve is in the "OFF"
position. Logs have been packaged separately to prevent damage to

1. Remove top and bottom louvers by simultaneously pulling both
top end spring latches towards the center of the appliance until
they are disengaged from locating holes. Repeat for bottom end
spring latches and pull outward. Reverse procedure to install
louvers back.
2. Remove the screen rod by sliding spring clip on one end to-
ward the center. Slide rod into screen rod hole until other end
of rod is free. Remove rod.
3. To open the glass door, open the pairs of latches located on the

tion when opening these latches.
4. Carefully open the door. The glass door is mounted to the fire-
box with 5 screws.
5. To remove the logs from the shrink wrap, carefully cut the
plastic around the perimeter of the log. Do not try to remove
the logs from the package without first cutting the plastic.
