INITIAL STARTUP
During manufacturing, fabricating and shipping, various components of this appliance are treated with certain
oils, films or bonding agents. These chemicals are not harmful, but may produce annoying smoke and smells as
they are burned off during the initial operation of the appliance. The initial break-in operation should last 2-3 hours
with the burner at the highest setting. The appliance must not be used with glassed doors in the closed position.
This can result reduced combustion and overheating.
