WARNINGFIRE OR EXPLOSION HAZARDFailure to follow safety warnings exactly could result in serious injury, death or property damage.— Donotstoreorusegasolineorotherflam-
mable vapors and liquids in the vicinity of this or any other appliance.
— WHAT TO DO IF YOU SMELL GAS• Donottrytolightanyappliance.• Donottouchanyelectricalswitch;do
not use any phone in your building.• Leavethebuildingimmediately.• Immediately call your gas supplier
from a neighbor’s phone. Follow the gas supplier’s instructions.
• Ifyoucannotreachyourgassupplier,callthefiredepartment.
— Installation and service must be per-formed by a qualified installer, serviceagency or the gas supplier.
WARNINGIf not installed, operated and maintained in accordance with the manufacturer's instructions, this product could expose you to substances in fuel or from fuel combustion which can cause death or serious illness.
INSTALLER: Leave this manual with the appliance.
CONSUMER: Retain this manual for future reference. Thisisanunventedgas-firedheater.Ituses
air (oxygen) from the room in which it is in-stalled. Provisions for adequate combustion and ventilation air must be provided. Refer to page 11.
WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERSWater vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30ml) of water for every 1,000 BTU's (.3KW's) of gas input per hour. Refer to page 8.
This appliance may be installed in an aftermarket permanently located, manufactured (mobile) home, where not prohibited by local codes.This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible for use with other gases.

• Donotplaceclothingorotherflammablematerialonorneartheappliance.
• Avoid the use of scented air fresheners (plug in type airfresheners, etc. ) while the burner is in operation. Air fresheners produce a residue in the air similar to candles and may produce a soot like substance.
• Avoid the use of scented or decorative candles while theburner is in operation. Candles produce a residue in the air that creates a soot like substance. Burning candles while the log setisoperatingmagnifiestheproblem.Itshouldbenotedthatcandles, in general, produce soot. The amount of time burned and the quantity of candles burned will determine the amount of soot produced and deposited.
• Installation and repair should be done by a QUALIFIED SERVICE PERSON. This appliance should be inspected before use and at least annually by a professional service person. More frequent cleaning may be required due to excessive lint from carpeting, bedding materials, etc. It is imperative that control compartments, burners and circulating air passageways of the appliance be kept clean.
• DONOTuse this room heater if any part has been under water. Immediatelycallaqualifiedservicetechniciantoinspecttheroom heater and to replace any part of the control system and any gas control which has been under water.
• Youmustoperateheaterwithfireplacescreeninplace.• Donotplacetrash,logsorotherarticlesonthelogsetduring
operation.• During manufacturing, fabricating and shipping, various
componentsofthisappliancearetreatedwithcertainoils,filmsor bonding agents. These bonding agents are not harmful but may produce annoying smoke and smells as they are burned off during initial operation of the appliance. This is a normal temporary occurrence. A window should be opened during the initial bake out period.
• Correctinstallationoftheceramicfiberlogs,properlocationofthe heater and annual cleaning are necessary to avoid potential problems with sooting. Sooting, resulting from improper installation or operation, can settle on surfaces outside the fireplace.Seeinstructionsforproperinstallation.
• WARNING: Do not allow fans to blow directly into the fireplace.Avoidanydraftsthatalterburnerflamepatterns.
• WARNING: Do not use a blower insert, heat exchanger insert or other accessory not approved for use with this heater.
• WARNING!Thisfireplaceneedsfreshairforventilationtorun properly. This fireplace has an ODS (oxygen depletionsensor) which will shut down the heater if adequate fresh air is not available. See troubleshooting section in the instructions.
• WARNING: DO NOT operate this appliance unless all components including logs, burners, and controls are in good working condition. Never operate this appliance if any log or twig is broken, or out of their intended position. Refer to the Log set placement instructions for correct log and twig positioning. Replacement components are available through your local dealer as indicated in the How to Order Repair Parts section of the appliance manual.
• Keepapplianceareaclearandfreefromcombustiblematerials,gasolineandotherflammablevaporsandliquids.
• WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
WARNINGWhen used without adequate combustion and ventilation air, heater may give off CARBON MONOXIDE, an odorless, poison-ous gas.
Do not install heater until all necessary provisions are made for combustion and ventilation air. Consult the writ-ten instructions provided with the heater for information concerning combustion and ventilation air. In the absence of instructions, refer to the National Fuel Gas Code, ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation, or applicable local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYS-TEM designed to turn off the heater if not enough fresh air is available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYSTEM!
If heater shuts off, do not relight until you provide fresh air.If heater keeps shutting off, have it serviced. Keep burner and control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Earlysignsofcarbonmonoxidepoisoningresembletheflu,with headache, dizziness and/or nausea. If you have thesesigns, heater may not be working properly. Get fresh air at once! Have heater serviced. Some people — pregnant women, persons with heart or lung disease,anemia,thoseundertheinfluenceofalcohol,thoseat high altitudes — are more affected by carbon monoxide than others.The pilot light safety system senses the depletion of oxygen at its location. If this heater is installed in a structure having a high vertical dimension, the possibility exists that the oxygen supply at the higher levels will be less than that at the heater. In this type of application, a fan to circulate the structure air will minimizethiseffect.Theuseofthisfanwillalsoimprovethecomfort level in the structure. When a fan is used to circulate air,itshouldbelocatedsothattheairflowisnotdirectedatthe burner.
