to shut off,shut off the manual gas valvebefore shutting off electrical supply.  \nWARNING-Do not use this furnace if any part hasbeen under water.Immediately call a qualified ser-vice technician to inspect the furnace and replaceany part of the control system and any gas controlthat has been under water.  \nCAUTION-Before attempting to perform any serviceor maintenance,turn electrical power off to unit atunit disconnect switch.  \n## I-IMPORTANT DIRECTIONS\n\n1-Keep furnace area clear and free of combustiblematerials,gasoline and other flammable vaporsand liquids.  \nIf installed in an insulated area,furnace must bekept free of insulating material.Insulating materialmay be combustible.  \nInspect unit venting system to make sure it is inplace,physically sound and without holes,corro-sion or blockage.  \nInspect return air duct to ensure duct is sealed tothe furnace and terminates outside the spacecontaining appliance.  \nInspect physical support of unit to guarantee thatit is sound without sagging,cracks,or gapsaround base and it maintains seal between baseand support.  \n2-Do not obstruct air flow to unit.Unit must receivean unobstructed flow of combustion and ventilat-ing air.  \n3-Do not store chlorine or fluorine products near unitor introduce these products into the combustionair.These products can cause furnace corrosion.  \n## 1I-LIGHTING INFORMATION AND OPERATION\n\nFOR YOUR SAFETY READ BEFORE LIGHTINGWARNING-If you do not follow these instructions ex-actly,a fire or explosion may result causing proper-ty damage,personal injury or loss of life.  \nBEFORE LIGHTING smell all around the appliance areafor gas.Be sure to smell next to the floor because somegas is heavier than air and will settle on the floor.  \nUse only your hand to push in or turn the gas controlknob.Never use tools.If the knob will not push in or turnby hand,do not try to repair it,cail a qualified servicetechnician.Force or attempted repair may result in a fireor explosion.  \nThis unit is equipped with an automatic gas valve usinga standing(constant)pilot flame or and intermittentpilot(“E”and“X”series units).Standing pilot unitsrequire manual lighting of pilot flame.Intermittent pilotmodels have a pilot ignitor.Do NOT try to manuallylight the pilot on an“E”or“×”series unit.  \n## A-Placing Furnace In Operation\n\nStanding Pilot Lighting Information  \nRefer to lighting instructions sticker on blower accesspanel and figure 2 for gas valve identification.  \n1-STOPI Read the pilot safety information in pre-vious section.  \n2-Set thermostat to lowest setting.See figure 3.  \n3-Turn off all electrical power to appliance.  \n4-Remove buner access panel.  \n5-Push in gas valve knob slightly and turn clockwiseto OFF.See figure 5.  \nNOTE-Knob
