Unlike the previous Model 8680, which used an 8-inch top-exit flue, Model 8681 uses a more versatile 6-inch flue that can be configured for either top or rear exit. An optional rear heat shield can significantly reduce rear clearance, and the optional convection blower mounts in conjunction with the rear heat shield to help circulate warm air throughout the room. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3 dir=\"auto\"\u003eFeatures \u0026amp;
