installation
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.
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.

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. For External
Vent Terminal Locations, see diagram in
the "Exterior Vent Termination Locations"
section.
6)
The arrow on the vent cap should be
pointing up.
Insure that the 1-1/2" clearances to
combustible materials are maintained (Diagram
3 in the "Venting Arrangement - Horizontal
Terminations" section) Install the termination
cap.
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
Note: If installing termination on a siding
covered wall, a vinyl siding standoff
or furring strips must be used to
ensure that the termination is not
recessed into the siding.
7)
Before connecting the horizontal run of vent pipe
to the vent termination, slide the Wall Thimble
over the vent pipe.
8)
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. Secure the connection between
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.
Note: With Dura-Vent, the minimum height is
achieved by installing a 45
o
elbow directly to
the rigid pipe adaptor.
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.

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
connection. Failure to do so may result in
drafting or performance issues not covered
under warranty.
