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.
