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. All horizontally terminated vent installations may only use
6-5/8”x 4” Security™ Secure Vent pipe*.
3. Assemble the desired combination of pipe and elbow(s)
to the appliance 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.
4. 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 9-1/4”x
10-1/4”. If the wall being penetrated is constructed of non-
combustible material (i.e. masonry block or concrete), a
7” diameter hole is acceptable and a wall thimble is not
required.
5. Horizontal runs of vent pipe must be supported every 3
feet. Wall straps - Simpson #988 or Security™ #SV4BM
- are available for this purpose.
6. If the vent passes through a ceiling or floor, a firestop
- Simpson #963 or Security™ #SV4BF - is required.
7. 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.
8. The horizontal run of vent should have a 1/4” (6mm)
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.
9. The location of the horizontal vent termination on an ex
-
terior 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
.
10. Allowable clearances from the vent pipe to combustible
materials must be maintained. See Page 8 for these clear
-
ances.
11. Do not locate the termination cap where it may be blocked
by shrubbery or snow.
* Other approved chimney brand is Simpson Dura-Vent DV-GS.
