INSTALLATION INSTRUCTIONS:
1. Plan your installation and clearances to combustibles. Decide on a location for the unit that will meet
the clearances noted in the venting section, and any or all local code requirements.

2. Set the appliance in the desired location. Determine if any wall studs,
electrical wiring, or plumbing pipes are in the way of the venting system as
it passes through the exterior wall. The fireplace location should be adjusted
if obstructions are found in the wall.
3. Project a line from the center point of the flue outlet upward and outward to
the desired flue outlet location on the exterior wall. Using this center point,

scribe a 10” (25.4 cm) hole or square on the
wall. Cut the hole from the interior through
the exterior wall surfaces.
4. Frame the hole as shown in Figure 29.
5. Trim the wall thimble to match the wall
thickness as necessary. Install the wall
thimble and secure it to the inner wall
frame using four (4) 1½” wood screws. If
a wall is greater than 8” (203mm) in depth,
the clearance above the flex must be 4⅜”
(111mm)

6. Apply a bead of Mill-Pac Black
sealant to the new Ø4” (10 cm) by
5” (12.5 cm) provided flue collar
adaptor. Press the flue collar into
the flue outlet of the fireplace so
that the Mill-Pac seals the flue
collar to the flue outlet.
7. Stretch both the Ø4” (10 cm) flex
vent and the Ø6⅝” (16.25 cm) flex
intake liner to the length needed
to ensure the flex can be easily
connected to the vent terminal.
8. Slide the Ø6⅝” (16.25 cm) flex
intake liner over the flex vent.
Install four (4) wire spacers
around the flex pipe. Ensure the
wire spacers are positioned at
either end of the pipes, and at
each end of any elbows in the
liners (refer to Figure 25 and 26).
