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. 25)
For combustible walls first frame in opening.
Combustible Walls (Fig. 25): Cut a 9³⁄₈”H x 9³⁄₈” W 

(240 x 240mm) hole through the exterior wall and 

frame.
Noncombustible Walls (Fig. 25): Hole opening must 

be 7.5” (190mm) in diameter.

STEP 2
Measure wall thickness and cut adjustable zero 

clearance sleeve parts to proper length (MAXIMUM 

12”/305mm). (Fig. 26) Adjust sleeve to minimum (9³⁄₈” x 

9³⁄₈” and attach to firestop with #8 sheet metal screws 

(supplied). Assemble sleeve and attach to firestop with 

#8 sheet metal screws (supplied). Install firestop as-

sembly.

STEP 3
Apply a bead of high temperature sealant to the inner 

and outer flue collars of the fireplace and using ap-

propriate venting component(s) attach to fireplace with 

three (3) screws. (Fig. 27) Follow with the installation 

of the inner and outer elbow. Again secure joints with 

three (3) sheet metal screws. Wipe off any excess high 

temperature sealant.

STEP 4
Measure the horizontal length requirement including a 

2” (50mm) overlap, i.e. from the elbow to the outside 

wall finish plus 2”, or the distance required if installing a 

second 90° elbow. (Fig. 28)
STEP 5
Use appropriate length of pipe section - telescopic or 

fixed - and install the horizontal vent sections. The 20” 

(508mm) section of pipe which goes through the wall is 

packaged with the 7TDVSK starter kit, and can be cut 

to suit if necessary. (Fig. 29)
