Heat is generated byboth realistic flames and glowing embers. Whenused without the blower, the fireplace insert re-quires no electricity making it ideal for emergencybackup heat.SAFETY DEvICEThis fireplace insert has a pilot with an OxygenDepletion Sensing (ODS) safety shutoff system.The ODS/pilot is a required feature for vent-freeroom heaters. The ODS system shuts off the fire-place insert if there is not enough fresh air.PIEzO IGNITION SYSTEMThis fireplace insert has a piezo ignitor. This sys-tem requires no matches, batteries or other sourcesto light fireplace insert.BLOWER ASSEMBLYThis fireplace insert is equipped with a blowerassembly. The blower operates thermostaticallyand has a variable control. The blower circulatesheated air from the fireplace insert into the room.Use of blower is optional.AiR FOR cOMBUSTiONAND VENTilATiONWARNING: This heater shallnot be installed in a confinedspace or unusually tight construc-tion unless provisions are provid-ed for adequate combustion andventilation air. Read the followinginstructions to insure proper freshair for this and other fuel-burningappliances in your home.Today’s homes are built more energy efficientthan ever. New materials, increased insulation andnew construction methods help reduce heat lossin homes. Home owners weather strip and caulkaround windows and doors to keep the cold air outand the warm air in. During heating months, homeowners want their homes as airtight as possible.While it is good to make your home energy effi-cient, your home needs to breathe. Fresh air mustenter your home. All fuel-burning appliances needfresh air for proper combustion and ventilation.Exhaust fans, fireplaces, clothes dryers and fuelburning appliances draw air from the house tooperate. You must provide adequate fresh air forthese appliances. This will insure proper ventingof vented fuel-burning appliances.PROVIDING ADEQUATEvENTILATIONThe following are excerpts from National FuelGas Code ANSI Z223.1/NFPA 54, Section 5.3, Airfor Combustion and Ventilation.All spaces in homes fall into one of the three fol-lowing ventilation classifications:1. 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 as con-struction 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 linesand at other openings.If your home meets all of the three criteriaabove, you must provide additional freshair. See Ventilation Air From Outdoors,page 8.If your home does not meet all of the threecriteria above, proceed to DeterminingFresh-Air Flow for Heater Location, page 7.
