The Napoleon S20I Wood Insert Manual provides installation and operating instructions for a wood-burning insert designed to fit into a solid fuel burning fireplace that is at least 14 inches deep, 25 7/8 inches wide, and 22 inches high, with an approved lined chimney at least 15 feet high and a hearth of 18 inches.1 This appliance is certified under the U.S. Environmental Protection Agency (EPA) standards and features clean-burning technology.1

Additional manuals are available for other Napoleon fireplace inserts, including models such as the 1101 and 1402, which are designed to burn natural wood only and must be installed by a qualified installer.34 These models require at least 14 square inches of outside air to be admitted to the room or directly to the unit through a 4-inch diameter pipe.34 The manuals emphasize safety precautions, including keeping children and pets away from the appliance when hot, not operating the unit with the glass door removed or cracked, and avoiding the use of chemicals, treated wood, or garbage as fuel.34

The 1101 and 1402 models meet the 2015 U.S. EPA crib wood emission limits and are tested and listed by Intertek Testing Services to standards ULC S628 and UL 1482.4 The manuals also include detailed sections on installation planning, clearance to combustibles, blower operation, air control, maintenance, and troubleshooting.34 For the most accurate and up-to-date information, users should refer to the specific model manual, which can be downloaded from Napoleon’s official website or authorized retailers.234
