UNIT INSTALLATION WITH HORI-
ZONTAL TERMINATION

4" X 6-5/8" OR 5" X 8" VENTING

(Rigid Vent Systems)
Minimum Vent Clearances
to Combustibles
* 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).
Horizontal Top* 2" (51mm)*
Horizontal Side 1-1/2 " (38mm)
Horizontal Bottom 1-1/2" (38mm)
Vertical Vent 1-1/2" (38mm)
Below are the recommended framing dimensions
(inside measurements) for the 4" x 6-5/8" and 5" x
8" rigid vent terminations - for use with a firestop
or wall thimble.
Recommended Framed Opening Size
Vent Size Framing Size
4" x 6 - 5/8" 10" x 10"
5" x 8" 11" x 11"
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
desired location. Put a bead of Mill-Pac inside
the outer section of the adapter and a bead of
on the inner collar. 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.
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. 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 2 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.
Note:
a) 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.
b) 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.

c) Snorkel Terminations:
For installations requiring a vertical rise on the
exterior of the building, 14-inch and 36-inch
tall snorkel terminations as shown in Diagram
2 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.
Diagram 2a
*As specified in CGA B149 Installation Code. Local codes or
regulations may require different clearances.
**Note: Riser vent is only for use in above grade terminations.
**NOTE: For snorkel terminations in
ABOVE grade installations, follow national
or local code requirements.
Vent riser is only available with 4" x 6-5/8"
venting. With 5" x 8" venting, use an op-
tional snorkel termination.
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. Do not attempt to enclose
the snorkel within the wall or any other type of
enclosure. See diagram 2c.

7. Ensure that the pipe clearances to combustible
materials are maintained (Diagram 5). 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.
