all insulation packing and flue plug block off from rear venting and proceed with fireplace installation. If you require a top-vented
unit, use the following steps to convert the fireplace before use.

Step 2: Remove the three screws that align with the clearance
screw holes from the top of the unit. Secure the center bracket
to the top center of the fireplace
Step 1: Remove two screws from the top and side of the unit. Bend the side bracket securing tab
over the edge of the unit and secure. Secure bracket to the top through the clearance screw hole.
Step 2: Remove the round flue cover from the top venting outlet.
Step 4: Make sure insulation disc is still in the round cover. Re-
move the flue plug from the top flue.
