Gas fire generates fumes. WARNING Fire Risk • For use with solid wood fuel or decorative gas appliance only. • DO NOT install unvented gas logs. WARNING Fire Risk Explosion Risk Inspect appliance and components for damage. Damaged parts may impair safe operation. • Do NOT install damaged components. • Do NOT install incomplete components. • Do NOT install substitute components Report damaged parts to dealer. in Vented Fireplaces”. • Must be installed in accordance with the National Fuel Gas Code, ANSI Z223.1. • A log set must incorporate a gas shutoff. • Log set requires the damper to be locked fully open. Knockouts are provided on both sides of the fireplace and in refractories for 1/2 in. (13 mm) iron pipe. • We recommend you seal refractory around pipe with fireplace mortar or high temperature, noncombustible sealant. • Repack insulation from the knockout around the pipe. • Maintain 1-1/2 in. (38 mm) air space around the pipe for 4 in. (102 mm) beyond the fireplace. • See Figure 7.1. Outer shell of fireplace Firebox Maintain air clearance to combustibles.

Micore Hearth Ext or equivalent insulation (see Table 11.2) Fireplace Protective Metal Hearth Strip Figure 8.1 Hearth Extension Construction Protective metal strips are placed 2 in. (51 mm) under the front of the fireplace and must extend beyond the front and sides of fireplace opening by 2 in. (51 mm). 1 in. (25 mm) overlap Figure 8.2 Positioning the Protective Metal Hearth Strips The hearth extension should slope away from the front of the fireplace and chase at 1/8 in. to 1/4 in. per foot. Spark strips must be used on top of any combustible hearth materials used for moisture management. This fireplace has been tested and approved for use with a hearth extension insulated to a minimum R value of 1.03. To substitute materials for the factory-available hearth extensions, see Figure 8.3 and calculate insulation alternatives as per Table 8.1 and the following formulas: • Thermal conductivity per inch thickness = k • k = (BTU)(inch) / (foot2)(hour)(°F) • Required thickness = Rk • Thermal resistance per inch thickness = r • r = (foot2)(hour)(°F) / (BTU)(inch) • Required thickness = R / rB.
