Air For Combustionand VentilationWARNING: This firebox shallnot be installed in a confinedspace or unusually tight construction unless provisions areprovided for adequate combustion and ventilation air. Read thefollowing instructions to insureproper fresh air for this andother fuel-burning appliancesin your home.Today’s homes are built more energy efficientthan ever. New materials, increased insulation andnew construction methods help reduce heat lossin homes. Home owners weather strip and caulkaround windows and doors to keep the cold air outand the warm air in. During heating months, homeowners want their homes as airtight as possible.While it is good to make your home energy efficient,your home needs to breathe. Fresh air must enteryour home. All fuel-burning appliances need freshair for proper combustion and ventilation.Exhaust fans, fireplaces, clothes dryers and fuelburning appliances draw air from the house tooperate. You must provide adequate fresh air forthese appliances. This will insure proper ventingof vented fuel-burning appliances.PROVIDING ADEQUATEVENTILATIONThe following are excerpts from National FuelGas 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 Construction2. Unconfined Space3. Confined SpaceThe information on pages 6 through 8 will helpyou classify your space and provide adequateventilation.Unusually Tight ConstructionThe air that leaks around doors and windowsmay provide enough fresh air for combustion andventilation. However, in buildings of unusuallytight construction, you must provide additionalfresh air.Unusually tight construction is defined asconstruction where:a. walls and ceilings exposed to the outside atmosphere have a continuouswater vapor retarder with a rating ofone perm (6 x 10-11 kg per pa-sec-m2) orless with openings gasketed or sealedandb. weather stripping has been added onopenable windows and doors andc. caulking or sealants are applied toareas such as joints around windowand door frames, between sole platesand floors, between wall-ceiling joints,between wall panels, at penetrationsfor plumbing, electrical and gas linesand at other openings.If your home meets all of the three criteriaabove, you must provide additional fresh air.See Ventilation Air From Outdoors, page 8.If your home does not meet all of the threecriteria above, proceed to DeterminingFresh-Air Flow For Heater Location.Confined and Unconfined SpaceThe National Fuel Gas Code, ANSI Z223.1/NFPA54 defines a confined space as a space whosevolume is less than 50 cubic feet per 1,000 Btuper hour (4.8 m3 per kw) of the aggregate inputrating of all appliances installed in that space andan unconfined space as a space whose volume isnot less than 50 cubic feet per 1,000 Btu per hour(4.8 m3 per kw) of the aggregate input rating ofall appliances installed in that space. Rooms communicating directly with the space in which theappliances are installed*, through openings notfurnished with doors, are considered a part of theunconfined space.* Adjoining rooms are communicating only ifthere are doorless passageways or ventilation grillsbetween them.determining fresh-air flowfor Heater locationDetermining if You Have a Confined orUnconfined SpaceUse this work sheet to determine if you have aconfined or unconfined space.Space: Includes the room in which you will installheater plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.Available from Allparts Equipment and Accessories - 1-877-475-5660 - www.allpartsinc.com

air for combustionand ventilationContinued1.Determine the volume of the space (length xwidth 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) 2,560 cu. ft.(volume of space)If additional ventilation to adjoining room issupplied with grills or openings, add the volumeof these rooms to the total volume of the space.2. Multiply the space volume by 20 to determinethe maximum Btu/Hr the space can support.(volume of space) x 20 (Maximum Btu/Hr the space can support)Example: 2,560 cu. ft. (volume of space) x 20 51,200 (maximum Btu/Hr the space can support)3.

Direct-vent draws combustion air from the outdoorsand vents to the outdoors.Example:40,000 Btu/HrGas water heater33,000 Btu/HrVent-free heater 73,000 Btu/HrTotal 4. Compare the maximum Btu/Hr the space cansupport 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 spacecan support)73,000 Btu/Hr (actual amount ofBtu/Hr used)The space in the example is a confined space becausethe actual Btu/Hr used is more than the maximumBtu/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 unconfinedspace, remove door to adjoining room or addventilation grills between rooms. See VentilationAir From Inside Building.B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, page 8.C. Install a lower Btu/Hr heater, if lower Btu/Hr sizemakes room unconfined.If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space isan unconfined space. You will need no additionalfresh air ventilation.WARNING: If the area inwhich the heater may be operated is smaller than that definedas an unconfined space or if thebuilding is of unusually tightconstruction, provide adequatecombustion and ventilation airby one of the methods describedin the National Fuel Gas Code,ANSI Z223.1/NFPA 54 Section 5.3or applicable local codes.VENTILATION AIRVentilation Air From Inside BuildingThis fresh air would come from an adjoining unconfined space. When ventilating to an adjoiningunconfined space, you must provide two permanentopenings: one within 12" of the ceiling and onewithin 12" of the floor on the wall connecting thetwo spaces (see options 1 and 2, Figure 2). Youcan also remove door into adjoining room (seeoption 3, Figure 2). Follow the National Fuel GasCode, ANSI Z223.1/NFPA 54, Section 5.3, Air forCombustion and Ventilation for required size ofventilation grills or ducts.12"VentilationGrills IntoAdjoiningRoom,Option 1Ventilation GrillsInto Adjoining Room,Option 2OrRemoveDoor intoAdjoiningRoom,Option312"Figure 2 - Ventilation Air from InsideBuildingAvailable from Allparts Equipment and Accessories - 1-877-475-5660 - www.allpartsinc.com
