PRODUCT FEATURES PRE-INSTALLATION PREPARATION Location and Space Requirements 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.
PRE-INSTALLATION PREPARATION Clearances Framing and Finishing 5 5 PRE-INSTALLATION PREPARATION Continued CLEARANCES Minimum clearances to combustibles for the fireplace are as follows: Back, and sides 0"/mm Perpendicular walls 6" (152mm) Floor 0"/mm Ceiling to louver opening 42" (1067mm) Front 36" (914mm) Top of Standoffs 0"/mm 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 .

VENTING INSTALLATION INSTRUCTIONS Installation Precautions 7 7 VENTING INSTALLATION INSTRUCTIONS NOTICE: Read these instructions completely before attempting installation. These models are tested and approved for use with DESA (directvent) 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.
