Local Codes Install and use fireplace with care. Follow all local codes. In the absence to local codes, use the current National Fuel Gas Code ANSI Z223.1/NFPA 54* (USA) or the current CSA-B149.1 Installation Code (Canada). *Available from: American National Standards Institute, Inc. 1430 Broadway New York, NY 10018 National Fire Protection Association, Inc.
Pre-Installation Preparation Continued • If you plan on installing a television or entertainment center recessed above your fireplace, it is recommended that you maintain a minimum 18" above top of louver opening. • When locating termination cap, it is important to observe the minimum clearances shown in Figure 7, page 8. • If recessing into a wall, you can avoid extra framing by positioning your fireplace against an already existing framing member. • Do not recess termination cap into a wall or siding.
Pre-Installation Preparation Continued framing and finishing Figure 5 shows typical framing of this fireplace. Figure 6 shows framing for corner installation. All minimum clearances must be met. For overall unit dimensions, framing allowances and vent collar locations, see Unit Dimensions, Figure 9, page 8. For available accessories for this fireplace, see Accessories on page 45. If you are using a separate combustible mantel piece, refer to Figure 7 and Figure 8, page 8 for proper height and clearances.

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 20, page 14). 1.
Venting Installation instructions Continued 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.
