Venting Installation NOTICE: Read these instructions completely before attempting installation. These models are tested and approved for use with FMI PRODUCTS, LLC (direct-vent) pipe components and terminations. The venting system must terminate on the outside of the structure and can not be attached to a chimney or flue system serving a separate solid fuel or gas burning appliance. A direct-vent appliance must have its own venting system. DO NOT common vent this appliance.
Venting Installation Continued INSTALLATION PLANNING There are two basic types of direct-vent installation: • Horizontal Termination • Vertical Termination Horizontal Termination Installation IMPORTANT: Horizontal square terminations require only inner portion of wall firestop. Horizontal installations using round termination require exterior portion of wall firestop available only in vent kit HTK (see Figure 14, page 11). 1.
Venting Installation Apply Mastic to All Four Sides Continued WARNING: Do not recess vent termination into any wall. This will cause a fire hazard. 6. Noncombustible Exterior Wall: Position horizontal vent cap in the center of 7 3 /4" round hole and attach to exterior wall with four wood screws provided. Before attaching vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around outside edges to make a seal between it and outside wall.

Venting Installation Continued installation for vertical termination Note: Vertical restrictor must be installed in all vertical installations. 1. 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 19) to avoid cutting load bearing members.
Venting Installation instructions Continued Note: If an offset is needed to avoid obstructions, you must support the vent pipe every 3 feet. Use wall straps for this purpose (see Figure 19, page 14). Whenever possible, use 45° elbows instead of 90° elbows. The 45° elbow offers less restriction to the flow of the flue gases and intake air. 5. Place the flashing over the pipe section(s) extending through the roof. Secure the base of the flashing to the roof and framing with roofing nails.
