INTRODUCTION WARNING: This product contains and/or generates chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. Models CD32M series, CD36M-A series and CD42M-A series are heat circulating gravity direct-vent fireplaces with sealed combustion chamber. These fireplaces use millivolt gas control valve and millivolt ignition system. These fireplaces are convertible with the standard setup as natural gas. Conversion may be performed by the O.E.M.
SELECTING LOCATION Continued • Do not locate appliance close to where gasoline or other flammable liquids may be stored. The appliance must be kept clear and free from combustible materials. • Do not use this appliance if any part has been under water.
