AIR FOR COMBUSTION AND VENTILATION WARNING ICON G 001 WARNING This fireplace must have fresh air for proper operation. If not, poor fuel combustion could result. 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. New materials, increased insulation, and new construction methods help reduce heat loss in homes.
AIR FOR COMBUSTION AND VENTILATION Continued DETERMINING AIR FLOW FOR FIREPLACE 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 fireplace 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). Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.
