A. Minimum Fireplace Opening Minimum fi replace opening requirements for a standard 3/4 inch deep surround are shown in Figure 5.1. For smaller openings, an optional 1-1/2 inch deep surround is available and dimensions are shown in Figure 5.2. WARNING! Risk of Fire or Burns! Provide adequate clearance around air openings and for service access. Due to high temperatures, the appliance should be located out of traffi c and away from furniture and draperies. • The fi rebrick (refractory), glass doors, screen rails, screen mesh and log grates can be removed from a factory built fi rebox in order to gain minimum gas insert opening requirements. • Any smoke shelves, shields and baffl es may be removed from the factory built fi rebox if attached with mechanical fasteners. • The metal fl oor of the solid fuel fi rebox may be removed to facilitate the installation of the insert. The appliance may not be placed directly on the base of the outer wrap, a 1/4 inch airspace must be provided between the insert and the fl oor of the outer wrap. Use the levelling legs to raise the insert a minimum of 1/4 inch. The original fi replace may never be returned to solid fuel in this condition. The sidewalls and top structure of the fi rebox may not be altered with the exception of removable baffl es and dampers. • Cutting of any sheet metal parts of the fi replace in which the gas fi replace insert is to be installed is prohibited, except the fl oor as tested for and as noted above.

Mantel and Wall Projections WARNING! Risk of Fire! Comply with all minimum clearances to combustibles as specifi ed. Framing or fi nishing material closer than the minimums listed must be constructed entirely of noncombustible materials (i.e., steel studs, concrete board, etc). Clearance to combustible material under the insert is 1/4 inch (6 mm). Clearance from top of fi replace opening for combustibles extending 12 inches max. is 12 inches. • Use leveling legs to raise insert minimum 1/4 inch (6 mm) above combustible material or outer wrap of factory built fi rebox. Combustible facings must not extend behind the insert surround. For non-combustible material specifi cations refer to section 1.E. Figure 5.3 Mantel Clearances 12 IN. MIN. 12 IN. MAX.
