UNIT INSTALLATION WITH HORIZONTAL TERMINATION
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 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 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, Dia. 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
connection. 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)
diameter (7-1/2"(191mm) dia. for flex) 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 Terminal 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
and the Riser Vent
Dia. 2 & 2a are available. Follow the
same installation procedures as used
for standard Horizontal Termination.
NEVER install the snorkel upside down.
Diagram 2
*As specified in CGA B149 Installation Code.
Local codes or regulations may require different
clearances.
Diagram 2a
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. Refer
to Snorkel Installation instructions for
details. Do not attempt to enclose the
Snorkel within the wall, or any other
type of enclosure.
6. The arrow on the vent cap should
be pointing up. Insure that the 1-1/2"
clearances to combustible materials are
maintained (Dia. 3.. Install the termination
cap. AstroCap
Horizontal Termination Caps may be used.
The four wood screws provided should
as shown in
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.
