7. Ensure that the pipe clearances to combustible

materials are maintained (Diagram 55). Install
the termination cap.

Note: If installing termination on a vinyl

siding covered wall, a vinyl siding
standoff or furring strips must be
used to ensure that the termination
is not recessed into the siding.

The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.

8. Before connecting the horizontal run of vent pipe

to the vent termination, slide the Wall Thimble
over the vent pipe. The wall thimble is required
for all horizontal terminations.

9. Slide the appliance and vent assembly towards

the wall carefully inserting the vent pipe into the
vent cap assembly. It is important that the vent
pipe extends into the vent cap sufficient distance
so as to result in a minimum pipe overlap of
1-1/4 inches (32mm). Secure the connection
between the vent pipe and the vent cap.

10. Install wall thimble in the center of the framed

hole and attach with wood screws.

Install the vent system according to the manufacturer's
instructions included with the components.

1. Set the unit in its desired location. Check to

determine if wall studs or roof rafters are in the
way when the venting system is attached. If this
is the case, you may want to adjust the location
of the unit. Rough in the gas preferably on the
right side of the unit and the electrical (junction
block is on the left side) on the left.

2. Direct Vent pipe and fittings are designed with

special twist-lock connections to connect the
venting system to the appliance flue outlet. A
twist-lock appliance adaptor is required.

3. In conjunction with the Approved Vent system,

install the adaptor after the unit is set in its de-
sired location. Slip the adapter over the existing
inner and outer flue collar. Fasten to the outer
collar only with the 3 supplied screws (drilling
pilot holes will make this easier).

4. Level the fireplace and fasten it to the framing

using nails or screws through the top and side
nailing strips.

Horizontal runs of vent must be supported every
3 feet (0.9meter). Wall straps are available for
this purpose.

6. Mark the wall for a square hole.-see chart to left

for size. The center of the square hole should
line up with the center-line of the horizontal pipe.
Cut and frame the square hole in the exterior
wall where the vent will be terminated. See

diagram 54 for center line requirements.

If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole is
acceptable.

Notes:

The horizontal run of vent must be level, or
have a 1/4 inch rise for every 1 foot of run
towards  the  termination.  Never  allow  the
vent  to  run  downward. This  could  cause
high  temperatures  and  may  present  the
possibility of a fire.

The location of the horizontal vent

termination on an exterior wall must meet all
local and national building codes, and must
not be blocked or obstructed. See "Exterior
Vent Termination Locations" section for
more details.

5. Assemble the desired combination of pipe and

elbows to the appliance adaptor and twist-lock
for a solid connection.

Note: For best results and optimum

performance with each approved
venting system, it is highly
recommended to apply “Mill-Pac”
sealant (supplied) to every inner
pipe connection. Failure to do so
may result in drafting or performance
issues not covered under warranty.

* Clearances noted below must be maintained;
except when passing through a wall, ceiling or at
the termination where the use of a firestop or wall
thimble reduces clearance to 1-1/2" (38mm).

c) Snorkel Terminations:

For installations requiring a vertical rise on the
exterior  of  the  building,  14-inch  and  36-inch
tall Snorkel Terminations  are available, as well
as the standard Riser Vent. Follow the same
installation  procedures  as  used  for  standard
Horizontal  Termination.  NEVER  install  the
snorkel upside down

Below Grade Snorkel Installation

If the snorkel termination must be installed below
grade, i.e. basement application, proper drainage
must be provided to prevent water from entering
the snorkel termination. See diagram 56. Do not
attempt to enclose the snorkel within the wall or
any other type of enclosure.
