Horizontal
Terminations
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 an available
option that must be used in conjunction with the
Simpson Dura-Vent Direct Vent system.
3. Put a bead of Mill-Pac inside the outer section
of the adapter and on the inner collar. Slip the
adapter over the existing inner and outer flue
collar and fasten to the outer collar only with the
3 supplied screws (drilling pilot holes will make
this easier). Level the fireplace and fasten it to
the framing using nails or screws through the
nailing strips.
4. Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.
Note:
a) Twist-lock procedure: Four indentations,
located on the female ends of pipes and
fittings, are designed to slide straight onto
the male ends of adjacent pipes and fittings,
by orienting the four pipe indentations so they
match and slide in to the four entry slots on
the male ends, Diagram 1. Push the pipe
sections completely together, then twist-lock
one section clockwise approximately one-
quarter turn, until the two sections are fully
locked. The female locking lugs will not be
visible from the outside, on the Black Pipe or
fittings. They may be located by examining
the inside of the female ends.
Diagram 1
NOTE: For best results and optimum perfor-
mance with each approved venting system,
it is highly recommended to apply "Mill-Pac"
sealant (supplied) to every inner pipe connec-
tion. Failure to do so may result in drafting
or performance issues not covered under
warranty.
b) Horizontal runs of vent must be
supported every three feet. Wall straps
are available for this purpose.
5. Mark the wall for a 10" x 10" square hole.
The center of the square hole should line
up with the centerline of the horizontal pipe.
Cut and frame the 10 inch square hole in
the exterior wall where the vent will be
terminated. If the wall being penetrated is
constructed of non-combustible material, i.e.
masonry block or concrete, a 7"(178mm)
dia. (7-1/2"(191mm) dia. for flex) hole is
acceptable.

Diagram 2
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 termi-
nation on an exterior wall must meet all
local and national building codes, and
must not be blocked or obstructed. For
External Vent Terminal Locations, see
diagram in the "Exterior Vent Termination
Locations" section.
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

*Dia 3, 3a & 4: As specified in CGA B149
Installation Code. Local codes or regulations
may require different clearances.
Below Grade 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. Refer
to Diagram 4. Do not attempt to enclose the
Snorkel within the wall, or any other type of
enclosure.
Diagram 4
NOTE: For Snorkel terminations
ABOVE
follow national or local code
requirements.
6. The arrow on the vent cap should
be pointing up. Insure that the 1-1/2"
clearances to combustible materials
are maintained (Diagram 4). Install the
termination cap.
