DURA-VENT
HORIZONTAL
TERMINATIONS
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.
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
installed on the unit at the factory. Assemble
the desired combination of pipe and elbows
to the appliance adaptor with pipe seams
oriented towards the wall or ceiling, as much
out of view as possible. The final positioning
of the pipe and 90 elbow assembly is
o
determined by the mounting orientation of
the adaptor on the stove and twist-locked
for a solid connection.

Regency U39-10 ULTIMATE Direct Vent Freestanding Gas Stove
®
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.
NOTE: For best results and optimum
performance with each approved
venting system, it is highly recom-
mended to apply "Mill-Pac" sealant
(supplied) to every inner pipe con-
nection. Failure to do so may result
in drafting or performance issues not
covered under warranty.
Hint: Apply
silicone to female
end.

b) Horizontal runs of vent must be
supported every three feet. Wall straps
are available for this purpose.
3. With the pipe attached to the stove, slide
the stove into its correct location, and mark
the wall for a 10" x 10" (inside dimensions)
square hole. The center of the square
hole should line up with the centerline of
the horizontal pipe, as shown in diagram
2. 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" diameter
hole is acceptable.
Diagram 2
Note:
a) The horizontal run of vent should 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 instructions in the
"External 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
as shown in Dia. 3 are available, as
well as the standard Riser Vent, see
Dia. 3a. Follow the same installation
procedures as used for standard
Horizontal Termination. NEVER install
the snorkel upside down.
*Dia 3, 3a & 4: As specified
in CGA B149 Installation
Code. Local codes or reg-
ulations may require
different clearances.
Diagram 3
NOTE: For Snorkel terminations in ABOVE
grade installations, follow national or local
code requirements.
Diagram 3a
Note: Riser Vent
is only for use
in above grade
terminations.
