Burn-in Period
During the fi rst few times of operation of this
appliance there will be some odor due to the
curing of the paint and burning off of lubricants
used in the manufacturing process. We recom-
mend that you open windows and ventilate the
house during the initial burns. The paint emits
non-toxic odors during this process.
Depending on your use, the burn-in period may
take a few hours or a few days.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE BURN-IN PERIOD. THE ODOR
AND HAZE EMITTED DURING THE BURN-IN
PERIOD CAN BE QUITE NOTICEABLE AND MAY
SET OFF A SMOKE DETECTOR.
If an optional blower is installed, Do not turn it
on during the Burn-In period.
