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 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 Continued • This fireplace requires a wall switch, hand-held remote or wall thermostat (millivolt) for operation (see Accessories, page 36). • This fireplace does not require electricity to operate. • Only the blower requires electricity if installed and if you plan to install the blower at a later date, do not forget to wire the outlet at the bottom of the fireplace when framing. • A piezo ignitor and ceramic electrode create spark to ignite the pilot light.
Pre-Installation Preparation Continued Clearances Minimum clearances to combustibles for the fireplace are as follows: Back and sides 0" Perpendicular walls 6" Floor 0" Ceiling to louver opening 42" Front 36" Top of Standoffs 0" Vent (See venting instructions for specific venting clearances.) Combustible material with a maximum thickness of 5/8" may be flush with the top front of fireplace. NOTICE: This fireplace is intended for use as supplemental heat.

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 as well as Simpson-Duravent 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.
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 available only in vent kit HTK (see Figure 14, page 11). 1.
Venting Installation instructions Apply Mastic to All Four Sides 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 7 3/4" round hole and attach to the exterior wall with four wood screws provided.

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 14. 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 7.
