New mate-rials, increased insulation, and new construction methods help reduceheat loss in homes. Home owners weather strip and caulk aroundwindows and doors to keep the cold air out and the warm air in. Duringheating months, home owners want their homes as airtight as possible.While it is good to make your home energy efficient, your homeneeds to breathe. Fresh air must enter your home. All fuel-burningappliances need fresh air for proper combustion and ventilation.Exhaust fans, fireplaces, clothes dryers, and fuel burning appliancesdraw air from the house to operate. You must provide adequate freshair for these appliances. This will insure proper venting of ventedfuel-burning appliances.WARNING: This heater shall not be installed in aconfined space or unusually tight construction un-less provisions are provided for adequate combus-tion and ventilation air. Read the following instruc-tions to insure proper fresh air for this and otherfuel-burning appliances in your home.PROVIDING ADEQUATE VENTILATIONThe following are excerpts from National Fuel Gas Code, ANSIZ223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.All spaces in homes fall into one of the three following ventilationclassifications:1. Unusually Tight Construction2. Unconfined Space3. Confined SpaceThe information on pages 4 through 6 will help you classify yourspace and provide adequate ventilation.Unusually Tight ConstructionThe air that leaks around doors and windows may provide enoughfresh air for combustion and ventilation. However, in buildings ofunusually tight construction, you must provide additional fresh air.OPTIONAL REMOTE CONTROL ACCESSORIESLOCAL CODESUNPACKINGPRODUCT FEATURESAIR FOR COMBUSTION AND VENTILATIONProviding Adequate VentilationOPTIONAL REMOTECONTROL ACCESSORIESPRODUCT FEATURESOPERATIONThis heater is clean burning.
