Install the Horizontal Termination Vent System
These instructions should be used as a guideline and do not supersede local codes in any way. Install venting
according to local codes, these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the
current standards of CAN/CGA-B149.1 in Canada.
Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.
Dégagement conforme aux codes d'installa tion locaux et aux exigences du foumisseunde gaz.
Horizontal vent systems terminate through an outside wall. Building Codes limit or prohibit terminating in
specific areas (Table 7).
The following figures and their associated horizontal vent tables illustrate the various configurations that are possible
for use with these fireplaces. Secure Vent
A table summarizes each configuration's minimum and maximum vertical and horizontal length parameters for a
variety of applications. For more information on connecting the vent pipe, see Page 22.
Figure 27: Typical Horizontal Vent Installation
1. Analyze the vent route and determine the number of vent sections and elbows required—See Effective Vent
Length on Page 21 for more information. Plan the venting so that a joint does not occur in the ceiling or roof
joists. Allow for elbows (Figure 20). Maintain the minimum clearances for combustibles (Page 24).
2. Frame the exterior wall opening—Locate the center of the vent outlet on the exterior wall (Table 10). Cut and/
or frame an opening, 10 1/2 x 12 1/8" (267 x 308 mm) inside dimensions, about this center.
3. Frame the ceiling opening—If the vertical route is to penetrate a ceiling, use plumb line to locate the center
above the fireplace. Cut and/or frame an opening, 10 1/2 x 10 1/2" (267 x 267 mm) inside dimensions, about
this center (Figure 22).
4. Attach the vent components to the fireplace—See Connecting the vent pipe on Page 22.
5. Attach the vent components to each other—See Connecting the vent pipe on Page 22.
6. Install the firestop/spacer at the ceiling—When using Secure Vent
joists; when using Secure Flex
the firestop/ spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the
firestop/spacer must be installed on the top side of the joist. Route the vent sections through the framed opening
and secure the firestop/spacer with 8d nails or other appropriate fasteners at each corner.
Maintain 1" (25 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running
vertical chimney sections.
NOTE: Attic insulation shield (96K94) must be installed when blown or loose-fill insulation is used, and is
recommended for all attic installations.
