STEP 3
Slide the zero clearance sleeve through the wall and
install the firestop on the inside surface of the wall.
Secure with four (4) #8 sheet metal screws.
STEP 4
Place fireplace into position. (Fig. 21) Measure the ver-
tical height (X) required from the base of the flue collars
to the center of the wall opening. NOTE: If using the
SK8DVSK Kit, the vertical section of pipe is telescopic
and could provide adjustment from 24” up to 40” (610
mm to 1016 mm).
Zero clearance sleeve is only required for
combustible walls.
STEP 5
Tape the inner and outer flue collars of the fireplace
using UL approved metal adhesive tape to ensure the
joints are sealed. Attach an appropriate length of vent
pipe to the fireplace. Follow with the installation of the
inner and outer elbow, tape elbow joints and secure
joints as described on Page 11.
STEP 6
Measure the horizontal length requirement including
a 2” (51 mm) overlap, ie from the elbow to the outside
wall face plus 2” (51 mm) (or the distance required if
installing a second 90° elbow). (Fig. 22)
Always install horizontal venting on a level
plane.

STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 19)
For combustible walls first frame in opening.
Combustible Walls: Cut a 16¹⁄₄”H x 16¹⁄₄” W (413 x
413 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls: Hole opening must be 11¹⁄₄”
(286 mm) in diameter.
Sidewall Installation
STEP 7
Use appropriate length of pipe sections and install the
horizontal vent sections. You may need to cut 1’ wall
section to size to be flush with the outside wall. The
sections which go through the wall are packaged with
the starter kit, and can be cut to suit if necessary. (Fig.
