1. Determine the location of the termination. (Fig. 20)
IMPORTANT: Vent must have a 2¹⁄₂” (64 mm) rise
for this application.
2. Locate the hole 24¹⁄₂” (622 mm) off the floor. This
is the center line of the termination. Refer to “Rear
Wall Installation Twist Lock Pipe” section.
3. Proceed with Step 3 of “Rear Wall Vent Application

2. Locate the hole 27¹⁄₄” (692 mm) off the floor. This
is the center line of the termination. Refer to “Rear
Wall Installation Twist Lock Pipe” section.
3. Mount the flex pipe assembly to the fireplace collars
and twist the collar that the flex pipe is attached to
onto the fireplace.

4. Once the collar is twisted onto the fireplace collar,
secure with a screw through the tab. (Fig. 15)
5. While sliding the fireplace into position, lift up the end
of the flex pipe and slip it through the firestop. *Be
careful not to extend the flex too much. The flex pipe
needs to have an immediate rise before going hori-
zontal. NOTE: Be careful not to distort the outer flex
as this will affect the performance of the fireplace.
6. Secure the collar to the firestop by bending the tab
out on the firestop and running a screw through the
tab and collar.
7. From outside the house, slide the termination onto
the collars sticking through the firestop.
8. Secure the termination to the house with the four (4)
screws provided. Be sure to seal around the termi-
nation and house cladding.
Vertical Sidewall Applications
Since it is very important that the vent-
ing system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.
The Vent Graph shows the relationship between vertical
and horizontal side wall venting and will help to deter-
mine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is 1”(25 mm)
on top, bottom and sides unless otherwise
noted.
When vent termination exits through foundations less
than 20” below siding outcrop, the vent pipe must
flush up with the siding. It is always best to locate the
fireplace in such a way that minimizes the number of
offsets and horizontal vent length.
