STEP 1
Locate vent opening on the wall. It may be necessary to
rst position the replace and measure to obtain hole location.
Depending on whether the wall is combustible or non-combus-
tible, cut opening to size. (Fig. 24)
(For combustible walls rst frame in opening. Fig. 24).

COMBUSTIBLE WALLS
: Cut a 9-3/8"H x 9-3/8"W (240
mm x 240 mm) hole through the exterior wall and frame as
shown (Fig. 24).
NON-COMBUSTIBLE WALLS
: Hole opening must be
7.5" (190 mm) in diameter.
STEP 2
Measure wall thickness and cut zero clearance sleeve parts to
proper length (MAXIMUM 12” / 305 mm). Assemble sleeve
and attach to restop with #8 sheet metal screws (supplied).
Install restop assembly (Fig. 25).
Zero clearance sleeve is only required for combustible walls.

STEP 4
Apply a bead of silicone to the inner and outer ue collars of
the replace and using three (3) screws attach an appropriate
length of vent to the replace. Follow with the installation of
the inner and outer elbow, again secure joints as described in
the section 'Joining DV Components'.
STEP 5
Measure the horizontal length requirement including a 2" (50
mm) overlap, i.e. from the elbow to the outside wall face plus
2" (50 mm)(or the distance required if installing a second 90º
elbow. (Fig. 27).
Always install horizontal venting on a level plane.
