Newmaterials, increased insulation, and new construction methods helpreduce heat loss in homes. Home owners weather strip and caulkaround windows and doors to keep the cold air out and the warm airin. During heating months, home owners want their homes as airtightas 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.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.Unusually tight construction is defined as constructionwhere:a. walls and ceilings exposed to the outside atmospherehave a continuous water vapor retarder with a ratingof one perm (6x10 -11 kg per pa-sec-m2 ) or less withopenings gasketed or sealedandb. weather stripping has been added on openable win-dows and doorsandWARNING: This heater shall not be installed in aconfined space or unusually tight construction unlessprovisions are provided for adequate combustion andventilation air. Read the following instructions to in-sure proper fresh air for this and other fuel-burningappliances in your home.LOCAL CODESInstall and use heater with care. Follow all local codes. In the absenceof local codes, use the latest edition of The National Fuel Gas Code,ANSI Z223.1/NFPA 54*.*Available from:American National Standards Institute, Inc.1430 BroadwayNew York, NY 10018National Fire Protection Association, Inc.Batterymarch ParkQuincy, MA 02269Note: Where listed vented decorative logs are required, thermo-stat operation is not permitted.OPERATIONThis heater is clean burning.

State and local codesin some areas prohibit the use of vent-free heaters. This heater mayalso be operated as a vented decorative (ANSI Z21.60) product byopening the flue damper (non-thermostat operation only).SAFETY PILOTThis heater has a pilot with an Oxygen Depletion Sensing (ODS)safety shutoff system. The ODS/pilot is a required feature for vent-free room heaters. The ODS/pilot shuts off the heater if there is notenough fresh air.PIEZO IGNITION SYSTEMThis heater has a piezo ignitor. This system requires no matches,batteries, or other sources to light heater.PRODUCT FEATURESUNPACKING1.
