Pre-Installation Preparation Location and space requirements Determine the safest and most efficient location for your DESA direct-vent fireplace. Make sure that rafters and wall studs are not in the way of the venting system. Choose a location where the heat output is not affected by drafts, air conditioning ducts, windows or doors. Figure 2 shows some common locations. Be aware of all restrictions and precautions before deciding the exact location for your fireplace and termination cap.

Venting Installation Instructions NOTICE: Read these instructions completely before attempting installation. These models are tested and approved for use with DESA (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 instructions 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 (see Figure 14, page 10. 1. Set the fireplace in its desired location and determine the route your horizontal venting will take.
Venting Installation instructions Continued Vent Cap WARNING: Do not recess vent termination into any wall. This will cause a fire hazard. 6. Noncombustible Exterior Wall: Position the horizontal vent cap in the center of the 8 1/2" round hole and attach to the exterior wall with four wood screws provided. Before attaching the vent cap to exterior wall, run a bead of non-hardening mastic (pliable sealant) around the outside edges to make a seal between it and the outside wall.

Venting Installation instructions 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 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. Be sure roofing material overlaps the top edge of the flashing as shown in Figure 19, page 13. There must be a 1" clearance from the vent pipe to combustible materials. 6. Continue to add pipe sections until the height of the vent cap meets the minimum building code requirements described in Figure 7 on page 6.
