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. 23) 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).

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 18.
STEP 6
Measure the horizontal length requirement including 
a 2” (50 mm) overlap, ie from the elbow to the outside 
wall face plus 2” (50 mm) (or the distance required if 
installing a second 90° elbow). (Fig. 24)

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 sec-
tions which go through the wall are packaged with the 
starter kit, and can be cut to suit if necessary. (Fig. 25)

Sealing firestop gaps with high temperature sealant 
will restrict cold air being drawn in around fireplace.
STEP 8
Guide the vent terminations 8” and 11” collars into their 
respective vent pipes. Double check that the vent pipes 
overlap the collars by 2” (51 mm). Secure the termina-
tion to the wall with screws provided and caulk around 
the wall plate to weatherproof. (Fig. 26) As an alterna-
tive to screwing the termination directly to the wall you 
may also use expanding plugs or an approved exterior 
construction adhesive.
