be dropped into the firebox for attachment to the flue collar. If the baffle and flue do not need to be
removed, you can skip to step 7.
Step Five
: Change the position of the flue collar if necessary. Locate the four bolts in the back of the
stove on the corners of the flue collar. To remove the flue collar, reach in through the flue collar and
turn off the nuts with a 7/16” wrench. Turn the collar into the desired location fitting the four holes on
the collar onto the four bolts left in the unit. Turn the nuts back onto the screws and tighten them with
the 7/16” wrench. The insert can now be placed into the fireplace opening and the flue liner (meeting
UL 1777) can be attached.
Step Six:
Remove the baffle.
NOTE
: Before the baffle can be removed, the 3 stone retaining clips (one
in the rear and one on each side) must be removed from the firebox. Remove the clips by removing the
bolts that hold them to the firebox. To remove the baffle / secondary air plenum assembly, first loosen
the two socket head bolts, located in the back of the firebox, that hold it in place with a 5/32” allen
wrench (see Photo #1). Once these bolts are loosened, lift the baffle assembly off the bolts and
maneuver it so it can be removed from the firebox.
Note
: If access to the top of the firebox is restricted, you will want to install the bracket for the surround
now. For installation details see step 10.
