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 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, 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.
NOTE: For best results and optimum perfor-
Diagram 1
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 as shown in Dia. 2 & 2a are available.
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,

*As specified in CGA B149 Installation Code.
Local codes or regulations may require different
clearances.
Diagram 2a
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
Termination Cap may be used.
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
7) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble (Part # 620-926) over the vent
pipe.
