New materials, increasedinsulation, and new construction methodshelp reduce heat loss in homes. Home ownersweather strip and caulk around windows anddoors to keep the cold air out and the warm airin. During heating months, home ownerswant their homes as airtight as possible.While it is good to make your home energyefficient, your home needs to breathe. Freshair must enter your home. All fuel-burningappliances need fresh air for proper com-bustion and ventilation.Exhaust fans, fireplaces, clothes dryers, andfuel burning appliances draw air from the houseto operate. You must provide adequate fresh airfor these appliances. This will insure properventing of vented fuel-burning appliances.PROVIDING ADEQUATEVENTILATIONThe following are excerpts from NationalFuel Gas Code, NFPA 54/ANS Z223.1, Sec-tion 5.3, Air for Combustion and Ventilation.All spaces in homes fall into one of the threefollowing ventilation classifications:1. Unusually Tight Construction2. Unconfined Space3. Confined SpaceThe information on pages 5 through 7 willhelp you classify your space and provideadequate ventilation.Unusually Tight ConstructionThe air that leaks around doors and win-dows may provide enough fresh air forcombustion and ventilation. However, inbuildings of unusually tight construction,you must provide additional fresh air.Confined and Unconfined SpaceThe National Fuel Gas Code ANS Z223.1defines a confined space as a space whosevolume is less than 50 cubic feet per 1,000Btu per hour (4.8 m3 per kw) of the aggre-gate input rating of all appliances installedin that space and an unconfined space as aspace whose volume is not less than 50cubic feet per 1,000 Btu per hour (4.8 m 3 perkw) of the aggregate input rating of allappliances installed in that space. Roomscommunicating directly with the space inwhich the appliances are installed*, throughopenings not furnished with doors, are con-sidered a part of the unconfined space.This heater shall not be installed in a con-fined space or unusually tight constructionunless provisions are provided for adequatecombustion and ventilation air.* Adjoining rooms are communicating onlyif there are doorless passageways or ventila-tion grills between them.ContinuedWARNING: This heater shallnot be installed in a confined spaceor unusually tight constructionunless provisions are providedfor adequate combustion and ven-tilation air. Read the following in-structions to insure proper freshair for this and other fuel-burningappliances in your home.Unusually tight construction is de-fined as construction where:a. walls and ceilings exposed to theoutside atmosphere have a con-tinuous water vapor retarder witha rating of one perm (6 x 10-11 kgper pa-sec-m2 ) or less with open-ings gasketed or sealedandb. weather stripping has beenadded on openable windows anddoorsandc. caulking or sealants are appliedto areas such as joints aroundwindow and door frames, be-tween sole plates and floors, be-tween wall-ceiling joints, be-tween wall panels, at penetra-tions for plumbing, electrical, andgas lines, and at other openings.If your home meets all of the threecriteria above, you must provide ad-ditional fresh air. SeeVentilation AirFrom Outdoors, page 7.If your home does not meet all of thethree criteria above, proceed toDeter-mining Fresh-Air Flow for Heater Lo-cation, page 6.
