Determining Vent Setup in the Combination Venting Unit
Combination venting units are shipped with rear venting setup nearly ready for install. If this is the type of vent you require, remove
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.

Remove the eight (8) screws holding the top vent cover
plate and gasket. Discard cover plate and reinstall screws.
Step 2
: Remove the round flue cover from the top venting outlet.
Step 3
: Remove insulation from inside flue pipe.
Step 4
: Make sure insulation disc is still in the round cover. Re-
move the flue plug from the top flue.
