This CO2 generator is intended for installation in a greenhouse only. This appliance shall not be installed in a confined space or unusually tight construction unless provisions are provided for adequate combustion and ventilation air. Produce Storage Areas Can Gas Code B-149.1 and 2-M95, Section 6.3.2 states “An appliance used in a produce storage area shall take its combustion air from outside the storage area”. Continued 105056 3 BLUE-FLAME VENT-FREE PROPANE/LP AND NATURAL GAS GREENHOUSE CO2 GENERATOR AIR FOR COMBUSTION AND VENTILATION Continued DETERMINING FRESH-AIR FLOW FOR APPLIANCE 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 appliance 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. (volume of space) Example: Space size 20 ft. (length) x 16 ft. (width) x 8 ft. (ceiling height) = 2560 cu. ft. (volume of space) If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space. 2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support. ________________ (volume of space) . 50 cu. ft. = (Maximum Btu/Hr the space can support) Example: 2560 cu. ft. (volume of space) . 50 cu. ft. = 51.2 or 51,200 (maximum Btu/Hr the space can support) 3. Add the Btu/Hr of all fuel burning appliances in the space. CO2 generator ______________________ Btu/Hr Example: Gas water heater* ______________________ Btu/Hr Gas water heater 40,000 Btu/Hr Gas furnace ______________________ Btu/Hr CO2 generator + 30,000 Btu/Hr Vented gas heater ______________________ Btu/Hr Total = 70,000 Btu/Hr Other gas appliances* + ______________________ Btu/Hr Total = ______________________ Btu/Hr * Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors. 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: 51,200 Btu/Hr (maximum the space can support) 70,000 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. You must provide additional fresh air. Your options are as follows: A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, page 5. B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 5. C. Install a lower Btu/Hr appliance, if lower Btu/Hr size makes room unconfined. If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation. WARNING: If the area in which the CO2 generator may be operated is smaller than that defined as an unconfined space or if the building is of unusually tight construction, provide adequate combustion and ventilation air by one of the methods described in the National Fuel Gas Code, ANSI Z223.1, 1992, Section 5.3, Canadian Gas Code B-149.1 and 2-M95, Section 7.2 and 7.3,or applicable local codes. Continued 4 105056 OWNER’S MANUAL 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). Follow the National Fuel Gas Code NFPA 54/ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation or Canadian Gas Code B-149.1 and 2-M95, Section 7.2 and 7.3 and/or applicable local codes for required size of ventilation grills or ducts. WARNING: Rework worksheet, adding the space of the adjoining unconfined space. The combined spaces must have enough fresh air to supply all appliances in both spaces. 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 5.3, Air for Combustion and Ventilation or Canadian Gas Code B-149.1 and 2-M95, Section 7.2 and 7.3 and/or applicable local codes...
