Readthe following instructions to in-sure proper fresh air for this andother fuel-burning appliances inyour home.Todayʼs homes are built more energy efficientthan ever. New materials, increased insulation, andnew construction methods help reduce heat lossin homes.

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 out-side 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 lines,and at other openings.If your home meets all of these threecriteria, you must provide additionalfresh air.
