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 5 through 7 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 (6 x 10-11 kg per pa-sec-m2 ) or less withopenings gasketed or sealedandb. weather stripping has been added on openable win-dows and doorsandc. caulking or sealants are applied to areas such asjoints around window and door frames, between soleplates and floors, between wall-ceiling joints, betweenwall panels, at penetrations for plumbing, electrical,and gas lines, and at other openings.If your home meets all of the three criteria above,you must provide additional fresh air. SeeVentilationAir From Outdoors, page 7.If your home does not meet all of the three criteria above,proceed toDetermining Fresh-Air Flow For Heater Loca-tion, page 6.Confined and Unconfined SpaceThe National Fuel Gas Code, ANSI Z223.1/NFPA 54 defines aconfined space as a space whose volume is less than 50 cubic feetper 1,000 Btu per hour (4.8 m3 per kw) of the aggregate input ratingof all appliances installed in that space and an unconfined space asa space whose volume is not less than 50 cubic feet per 1,000 Btu perhour (4.8 m3 per kw) of the aggregate input rating of all appliancesinstalled in that space. Rooms communicating directly with thespace in which the appliances are installed*, through openings notfurnished with doors, are considered a part of the unconfined space.* Adjoining rooms are communicating only if there are doorlesspassageways or ventilation grills between them.PRODUCT FEATURESOPERATIONThis heater is clean burning. It requires no outside venting. There isno heat loss out a vent or up a chimney. Heat is generated by bothrealistic flames and glowing coals. This heater is designed for vent-free operation with flue damper closed. It has been tested andapproved to ANSI Z21.11.2 standard for unvented heaters. State andlocal codes in some areas prohibit the use of vent-free heaters. Thisheater may also be operated as a vented decorative (ANSI Z21.60)product by opening the flue damper (Non-Thermostat Models Only).SAFETY DEVICEThis 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 FEATURESAIR FOR COMBUSTION AND VENTILATIONProviding Adequate Ventilation
