VENTING INSTALLATION Installation Precautions Installation Planning VENTING INSTALLATION WARNING: Read all instructions completely and thoroughly before attempting installation. Failure to do so could result in serious injury, property damage or loss of life. Operation of improperly installed and maintained venting system could result in serious injury, property damage or loss of life. WARNING: Horizontal sections of this vent system require a minimum clearance of 2" (5.
VENTING INSTALLATION Installation Planning (Cont.) Installation for Horizontal Termination VENTING INSTALLATION Continued Snorkel Installing Vent System in a Chase A chase is a vertical box-like structure built to enclose venting that runs along the outside of a building. A chase is not required for such venting. NOTICE: Treatment of firestops and construction of the chase may vary from building type to building type. These instructions are not substitutes for the requirements of local building codes.
VENTING INSTALLATION Installation for Horizontal Termination (Cont.) VENTING INSTALLATION Continued 3. 4. Attach vent pipe assembly to the burner system. Set stove in front of it’s permanent location to insure minimum clearances. Mark the wall for a 10" (25.4 cm) square hole (for noncombustible material such as masonry block or concrete, a 7 1/2" [19.1 cm] diameter hole is acceptable). See Figure 25. The center of the hole should line up with the center-line of the horizontal rigid vent pipe.
VENTING INSTALLATION Installation for Horizontal Termination (Cont.) VENTING INSTALLATION Continued Horizontal Termination Configurations Figures 31 through 33 show different configurations for venting with horizontal termination. Each figure includes a chart with vertical minimum/maximum and horizontal maximum dimensions which must be met. Seal all connections with high temperature silicone sealant (outer pipe only) as specified in the second warning statement on page 12.
VENTING INSTALLATION Installation for Vertical Termination VENTING INSTALLATION Continued INSTALLATION FOR VERTICAL TERMINATION Flat Ceiling Installation 1. NOTICE: Use rigid pipe only. Flex venting is not to be used with a vertical termination. 1. 2. Determine the route your vertical venting will take. If ceiling joists, roof rafters, or other framing will obstruct the venting system, consider an offset (see Figure 34) to avoid cutting load bearing members.
VENTING INSTALLATION Installation for Vertical Termination (Cont.) 17 17 VENTING INSTALLATION Continued 6. Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements described in Figure 23 on page 11. Note: You must increase vent height for steep roof pitches. Nearby trees, adjoining rooflines, steep pitched roofs, and other similar factors may cause poor draft or down-drafting in high winds. Increasing the vent height may solve this problem. 7.
