Local Codes Install and use fireplace with care. Follow all local codes. In the absence of local codes, use the latest edition of The National Fuel Gas Code ANSI Z223.1/NFPA 54*.
Hood Assembly WARNING: Always have screen in place before operating fireplace. This prevents excessive temperatures on fireplace surfaces. Sheet Metal Screws Louver Firebox Top Hood WARNING: Failure to position the parts in accordance with these diagrams or failure to use only parts specifically approved with this fireplace may result in property damage or personal injury.

AIR FOR COMBUSTION AND VENTILATION Continued PROVIDING ADEQUATE VENTILATION The following are excerpts from National Fuel Gas Code, ANSI Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation. All spaces in homes fall into one of the three following ventilation classifications: 1. Unusually Tight Construction 2. Unconfined Space 3. Confined Space The information on pages 6 through 8 will help you classify your space and provide adequate ventilation.
AIR FOR COMBUSTION AND VENTILATION Continued 4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used. ________ Btu/Hr (maximum the space can support) ________ Btu/Hr (actual amount of Btu/Hr used) Example: 35,840 Btu/Hr (maximum the space can support) 40,000 Btu/Hr (actual amount of Btu/Hr used) The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.
Installation NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install fireplace. Follow all local codes.

INSTALLATION Terminal “W” Continued W 3. Route the 25 ft. wire to a convenient location to mount your thermostat (no outside wall). IMPORTANT: The wire may be shortened but must not be lengthened. The thermostat should be mounted 54" above the floor in a location where there is good air circulation. Avoid heat sources such as lamps, direct sunlight, fireplace, or heat and air conditioning ducts. 4. Gently remove the cover of the thermostat from the base.
INSTALLATION Continued 2. Reattach screen by placing the notches in the screen frame over the shoulder screws and pushing down. Log 4. Remove log packaging material and discard. Gently place log over burner (see Figure 39). (Do not allow log to contact flame as this will create sooting.) 5. Insert each rod through ten rings located at top of screen (see Figure 40).
INSTALLATION LIGHTING INSTRUCTIONS Continued 6. Insert first rod into hole in left side of firebox. Fasten rod to rear hole near center of firebox using black Phillips head screw (see Figure 40, page 21). 7.
