Horizontal Vent Installation

Venting terminals may not be recessed into a wall or siding.
1. Set the unit in the desired location. Check whether or not wall studs
are in the way when the venting system is attached. If wall studs are
in the way, you may want to adjust the location of the unit.
2. Any stove that is horizontally terminated and has a vertical section
of pipe off the top of the stove, that first section of pipe must be a
minimum of 18" long.
3. All horizontally terminated vent installations may only use 6­5/8"x 4"
Security™ Secure Vent pipe*.
4. Assemble the desired combination of pipe and elbow(s) to the appli­
ance adapter with pipe seams facing down. Offsetting the pipe seams
as double seams in one place will cause the outer pipe to take an oval
shape.
5. When this pipe passes through a wall, a wall thimble ­ Simpson #942
or Security™ #SV4RSM ­ is required. The hole in the wall for the
wall thimble should be 9­1/4"x 10­1/4". If the wall being penetrated
is constructed of non­combustible material (i.e. masonry block or
concrete), a 7" diameter hole is acceptable and a wall thimble is not
required.
6. Horizontal runs of vent pipe must be supported every 3 feet. Wall
straps ­ Simpson #988 or Security™ #SV4BM ­ are available for this
purpose.
7. If the vent passes through a ceiling or floor, a firestop ­ Simpson #963
or Security™ #SV4BF ­ is required.
8. Also note that venting terminals shall not be recessed into a wall or
siding. If installing the termination cap on a wall covered with vinyl
siding, a vinyl siding standoff ­ Simpson #950 or Security™ #SV4VS
­ or furring strips must be used to ensure that the termination cap is
not recessed into the siding.
9. The horizontal run of vent should have a 1/4" rise for every 12" of run
toward the termination. Never allow the vent to run downward. This
could cause high temperatures and may present the possibility of a
fire.
10.If the wall being penetrated is constructed of noncombustible material,
such as masonry block or concrete, an 7" diameter hole is acceptable
and a wall thimble is not required..
11. 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 allowable external vent termination locations (see
Page 17).
12. Allowable clearances from the vent pipe to combustible materials must
be maintained. See Page 9 for these clearances.
13. Do not locate the termination cap where it may be blocked by shrub­
bery or snow.
* Other approved chimney brand is Simpson Dura­Vent DV­GS.
