Air For Combustion and Ventilation WARNING: This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes. Read the following instructions to insure proper fresh air for this and other fuel-burning appliances in your home. Today’s homes are built more energy efficient than ever.
Air For Combustion and Ventilation Continued DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this work sheet to determine if you have a confined or unconfined space. Space: Includes the room in which you will install heater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms. 1. Determine the volume of the space (length x width x height). Length x Width x Height =_______cu. ft.
AIR FOR COMBUSTION AND VENTILATION Continued VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 3). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.
INSTALLATION Continued IMPORTANT: Vent-free gas log heaters add moisture to the air. Although this is beneficial, installing firebox in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 6. IMPORTANT: Make sure firebox is level. If firebox is not level, log set will not work properly. Note: Your firebox is designed to be used in zero clearance installations.
INSTALLATION Continued NOTICE: If your installation does not meet the minimum clearances shown, you must do one of the following: • raise the mantel to an acceptable height • remove the mantel Built-In Firebox Installation Built-in installation of this firebox involves installing firebox into a framed-in enclosure. This makes the front of firebox flush with wall. Optional brass trim accessories are available (see Accessories, page 17). The brass trim will extend past sides of firebox approximately 1/2".
