WARNING: Indicatesahazardoussituationwhich, ifnotavoided,couldresultindeathorseriousinjury.

CAUTION: Indicates a hazardous situationwhich, if not avoided,couldresultinminorormoderateinjury.

NOTICE:Addressespracticesnotrelatedtopersonalinjury.• An unvented room heater having an input rating of more than

6,000 Btu per hour shall not be installed in a bathroom• An unvented room heater having an input rating of more than 10,000

Btu per hour shall not be installed in a bedroom or bathroom.• Due to high temperatures, the appliance should be located out of

traffic and away from furniture and draperies.• Children and adults should be alerted to the hazard of high surface

temperature and should stay away to avoid burns or clothing ignition.

• Young children should be carefully supervised when they are in the same room with the appliance.

• Do not place clothing or other flammable material on or near the appliance.

• Avoid the use of scented air fresheners (plug in type air fresheners, 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 the burner is in operation. Candles produce a residue in the air that creates a soot like substance. Burning candles while the log set is operating magnifies the problem. It should be noted that candles, 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.

• DO NOT use this room heater if any part has been under water. Immediately call a qualified service technician to inspect the room heater and to replace any part of the control system and any gas control which has been under water.

• You must operate heater with fireplace screen in place. • Do not place trash, logs or other articles on the log set during

operation.• During manufacturing, fabricating and shipping, various

components of this appliance are treated with certain oils, films or 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.

• Correct installation of the ceramic fiber logs, proper location of the 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. See instructions for proper installation.

• WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner flame patterns.

• WARNING: Do not use a blower insert, heat exchanger insert or other accessory not approved for use with this heater.

• WARNING! This fireplace needs fresh air for ventilation to run properly. This fireplace has an ODS (oxygen depletion sensor) 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.

• Keep appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

• 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.

Early signs of carbon monoxide poisoning resemble the flu, with headache, dizziness and/or nausea. If you have these signs, 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, those under the influence of alcohol , those at 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 minimize this effect. The use of this fan will also improve the comfort level in the structure. When a fan is used to circulate air, it should be located so that the air flow is not directed at the burner.

You must secure the gas appliance to the fireplace floor. If not, the entire unit may move when you adjust the controls. Movement of unit may cause shifting of the optional decorative glass. Burner movement could cause a gas leak.Special care is required if you are installing the unit into a sunken fireplace. You must raise the fireplace floor to allow access to gas controls. This will insure adequate air flow and guard against sooting. Raise the fireplace floor using noncombustible materials.

VFIU24 LIGHTING INSTRUCTIONS

FOR YOUR SAFETY READ BEFORE LIGHTING

WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

LIGHTING INSTRUCTIONS

A. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS• Do not try to light any appliance.• Do not touch any electrical switch.• Do not use any phone in your building.• Immediately call your gas supplier from a neigh-

bor's phone. Follow the gas supplier's instructions.• If you can not reach your gas supplier, call the fire

department.

B. Use only your hand to push in or turn the gas control knob. Never use tools. If the knob will not push in or turn by hand, don't try to repair it, call a qualified ser-vice technician. Force or attempted repair may result in a fire or explosion.

C. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

1. STOP!Readthesafetyinformationaboveonthispage.2. Openbottomlouverassembly,(ifapplicable).3. Pressthe"I/O"(ON/OFF)buttononthevalvetofaceto"O"
