Safety information Continued This fireplace must be installed by a qualified (certified or licensed) service person. It has a sealed gas combustion chamber that uses a coaxial pipe (pipe within a pipe and having the same center) venting system. It brings in fresh air for combustion through the outer pipe and combustion gases are exhausted through the inner pipe. If the glass door assembly and venting pipe are not properly seated, connected and sealed, carbon monoxide leakage (spillage) can occur.
Safety information Product Identification Continued 2. If you smell gas • shut off gas supply • do not try to light any appliance • do not touch any electrical switch; do not use any phone in your building • immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier's instructions • if you cannot reach you gas supplier, call the fire department. 3.
Product Features These are a few facts that can help you understand and enjoy your direct-vent fireplace: • The venting system may be routed to the outside of your home in several ways. It may vent through the roof (vertical) or it may vent to an outside/exterior wall (horizontal). The vent pipe installation is very important to allow for proper operation. You must follow the venting instructions very carefully for either vertical or horizontal applications.
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.

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 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 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.

Fireplace Installation Continued CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of volume will occur. Installation must include an equipment shutoff valve, union and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 31).
