FRESH AIR FOR COMBUSTION AND VENTILATION WARNING ICON G 001 WARNING This heater 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.
FRESH AIR FOR COMBUSTION AND VENTILATION Continued DETERMINING FRESH-AIR FLOW FOR HEATER LOCATION Determining if You Have a Confined or Unconfined Space Use this worksheet 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.
FRESH 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 2). You can also remove door into adjoining room (see option 3, Figure 2).
FRESH AIR FOR COMBUSTION AND VENTILATION Continued VENTILATION AIR (Continued) Ventilation Air From Outdoors Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.
INSTALLING TO WALL NOTICE A qualified service person must install heater. Follow all local codes. CHECK GAS TYPE Use only propane gas. If your gas supply is not propane, do not install heater.
