Rear Wall Vent Installation

Twist Lock Pipe

Step 1

Locate and cut the vent opening in the wall.

For combustible walls ﬁrst frame in opening. (Fig. 22)

NOTE: When using ﬂex vent, the opening will have to

be measured according to the 1” (25mm) rise in 24”

(610mm) vertical run.

Combustible Walls:

Cut a 10³⁄₈”H x 9³⁄₈” W (265 mm

x 240 mm) hole through the exterior wall and frame as

shown. (Fig. 22)

Noncombustible Walls: Hole opening should be 7¹⁄₂”

(191mm) diameter.

Zero clearance sleeve is only required for

combustible walls.

Step 2

Measure wall thickness and cut zero clearance sleeve

parts to proper length (Maximum 12” / 305 mm). As-

semble sleeve to its maximum opening (10³⁄₈” x 9³₈”)

and attach to ﬁrestop assembly. (Fig. 23)

Step 3

Measure the horizontal length requirement for the vent-

ing including a 2” (51 mm) overlap, i.e. from the elbow

to the outside wall face plus 2” (51 mm). (Fig. 21)

Step 4

Install the 4” (102 mm) vent to the appliance collar and

secure with 3 sheet metal screws. Install the 7” (178

mm) vent pipe to the appliance collar and secure with 3

sheet metal screws. It is not necessary to seal this con-

nection. If a 45° elbow is being used attach the elbow

to the appliance in the same manner then attach the

venting to the elbow.

It is critical that there is no downward

slope away from the appliance when con-

necting the vent or elbow.

Step 5

Guide the venting through the vent hole as you place

the appliance in its installed position. Guide the 4”

(102 mm) and 7” (178 mm) collar of the vent termina-

tion into the outer ends of the venting. Do not force

the termination. If the vent pipes do not align with the

termination, remove and realign the venting at the appli-

ance ﬂue collars. (Fig. 24) Attach the termination to the

wall as outlined in the instruction sheet supplied with

the termination.
