During manufacturing, fabricating, and shipping, various components of this appliance are treated with certain oils, fi lms, 

or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as they burn off the 

fi rst time the appliance is used. Operate the appliance 2 to 3 hours at the highest setting to burn off all the oils, fi lms, etc.

fi replace. Always operate this appliance with the fi replace screens in place.
