Pre-Installation Preparation Continued • Your fireplace is designed to be used in zero clearance installations. Wall or framing material can be placed directly against any exterior surface on the back, sides or top of your fireplace, except where standoff spacers are integrally attached. If standoff spacers are attached to your fireplace, these spacers can be placed directly against wall or framing material. See framing details on page 7.
Pre-Installation Preparation 1 2 Continued 3 A framing and finishing 36 /8" 1 Wall 4 Figure 4 shows typical framing of this fireplace. Figure 5 shows framing for corner installation. All minimum clearances must be met. For available accessories for this fireplace, see Accessories on page 35. If you are using a separate combustible mantel piece, refer to Figure 6 for proper installation height. You can install noncombustible mantels at any height above the fireplace.

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 12). 1.
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 15. 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 8.
